Multiple copies
About MOPY printing
Mopy printing enables you to print multiple, collated copies of a document. Documents are processed once and printed multiple times. This optimizes processing time, minimizes printing time, and reduces network traffic. Mopy printing begins as soon as pages are available you don't have to wait for the entire document to be processed. As a document is processed, the printer stores the document image on its internal hard disk. Additional copies are printed at maximum speed because the document image is replayed to produce the number of copies specified (in the print job or on the printer's control panel). Mopy printing is useful for complex jobs that slow down the printer when the first copy is created or take a long time to transmit over a network. Note The printer's internal hard disk has over 700MB of free disk space enough to hold a document over 5,000 pages long. If you're printing multiple copies of a document over 5,000 pages long, try a test printing to make sure there is enough disk space to store the entire document. If necessary, you can break up a large print job into smaller sub-jobs.
Chapter 2: Using Enhanced Features 7
The front panel of the D640 printer includes settings you can use to make multiple-page, collated copies. These settings include:
l l l
Copies. This setting specifies the number of copies for each page of a document. Copies are created on a page-by-page basis. Mopies. This setting is compatible with the multiple copy (mopy) feature in the HP Laserjet 5Si Mopier printer driver. It creates multiple collated copies on a document-by-document basis. Auto-collate. Used in combination with the Copies setting, autocollate enables you to print multiple-page, collated copies. This setting is useful if your printer driver doesn't support mopy functions (for example, the HP Laserjet 4Si printer driver). Copies (no collate) Mopies

This feature is useful if you're simulating a multi-part form on the printer and you want more than one copy of the form.
Working with printer drivers
Application and printer driver settings influence the multiple-copies settings on the printer. To make sure you get the desired results, Hewlett-Packard recommends you test the multiple-copy features on the printer with your specific application and printer driver. Some things to remember about multiple, collated copies include:
l l
Settings in the printer driver and application override settings on the printer's control panel. Commands in a print job override settings on the printer's control panel.
The table on page 10 shows some examples of how the D640 printer's auto-collate setting works with your application/printer driver.

General rule: If you're using the printer's auto-collate feature, leave collate Off in the Laserjet 4Si driver (or D640 NT driver) and On in the Laserjet 5Si Mopier driver. Otherwise, leave collate Off.
Note
If you're not sure you're getting printer-efficient, multiple copies, check the printer's control panel when the job is printing. You should see a Mopies indicator.

Chapter 2: Using Enhanced Features 13
TIFF emulation
About TIFF emulation
TIFF emulation enables the printer to recognize and print bi-level monochrome TIFF documents. Previously, TIFF images had to be part of a larger PCL or PostScript (PS) document to be printed. You can set TIFF emulation as the default printer protocol, or you can use Auto emulation to automatically select between PCL, PS, and TIFF protocols. TIFF emulation does not support color or grayscale TIFF files. For more information about TIFF emulation, see "Working with TIFF images" on page 29.
Setting TIFF emulation
CAUTION Setting TIFF emulation as the default printer protocol, should be done only in a controlled environment where TIFF is the only type of file printed. Hewlett-Packard highly recommends using Auto emulation instead. If the printer is set to TIFF and a PS or PCL job is sent, you get pages and pages of blank paper or unrecognizable print characters because the printer is expecting TIFF data, not PCL or PS. To set TIFF emulation as the default printer protocol: Step 1 Locate the control panel on the front of the printer and press Menu. A list of menus appears with Printing highlighted. Step 2 Press to open the Printing menu.
A list of Printing settings appears. Step 3 Scroll though the list of settings until emulation is highlighted.

If you don't press Save, the change remains active until the printer is reset or a new configuration is loaded. TIFF documents are typically designed to take up the entire page. To prevent clipping of the image when you print, make sure Clip = Off is set in the Configuration menu or in your print job.

Working with TIFF images
About TIFF images
The D640 printer supports TIFF emulation which enables your printer to recognize and print bi-level, monochrome TIFF images. Previously, TIFF images had to be part of a larger PCL or PostScript (PS) document to be printed. TIFF support for the D640 printer conforms to the specifications described in TIFF Revision 6.0 published by Aldus Corporation, June 1992. The information in this chapter assumes you are familiar with TIFF Revision 6.0 .
Chapter 3: Technical Reference 29
The D640 printer supports relevant parts of Baseline TIFF and selected elements of Extended TIFF. There are no private fields or values required by the printer. Note The TIFF standard does not contain any elements to indicate the termination of data. Therefore, termination of a TIFF file must be indicated by PJL universal escape sequences or the printer's I/O timeout configuration.
Printing TIFF images
TIFF images can be printed using the following methods:
l l
setting the printer's control panel to recognize TIFF files (Emulation = TIFF or Auto). Auto is the recommended setting if you print files using more than one protocol (such as PCL or PS). using commands in a print job
Using the control panel
On the printer's control panel, you can explicitly select TIFF emulation. For details, see "TIFF emulation" on page 14. When TIFF emulation is set, the following data items are valid:
l l
A new TIFF file, starting with a 4-byte sequence $49492A00 or $4D4D002A PJL commands
Any other type of data is treated as an error. On the printer's control panel, you can also use the Auto emulation setting to implicitly recognize TIFF files. If Auto emulation is set, the printer recognizes either of the following sequences as valid TIFF file headers and enters TIFF emulation mode automatically, if this sequence is at the start of the print job.
l
$49492A00 or $4D4D002A
30 Chapter 3: Technical Reference
Using commands in a print job
In addition to control panel settings, TIFF protocol can be selected by the PJL command:
@PJL ENTER LANGUAGE = TIFF
The following is a sample print job for a TIFF file:
%-12345X@PJL JOB NAME="Sample.tif" %-12345X@PJL SET CLIP=OFF %-12345X@PJL ENTER LANGUAGE=TIFF < tif file goes here > %-12345X@PJL @PJL EOJ NAME="Sample.tif" %-12345X
General rules
The following are some general rules to describe how the D640 printer processes TIFF data.
l
l l
Each TIFF file is a self-contained unit, made up of one or more sub-files. Each sub-file describes a single rectangular image. The image may be a complete page, or it may be a part of a page. During TIFF emulation, the printer cannot switch into any other protocol, except at the boundaries of individual TIFF files. If a TIFF image contains multiple sub-files, the images contained in the sub-files are placed on separate pages in the order the sub-files appear in the TIFF data stream. If TIFF is the selected protocol: · Images are placed with respect to the physical page, with zero margins. · If a sub-file doesn't have positioning information, the image is placed at the edge of the page. · If a sub-file has positioning information, the commands are interpreted as absolute displacements from the edge of the physical page.
Chapter 3: Technical Reference 31
· The Clip setting for the document determines if the image is printed to the edge of the page.
This can be a common situation. TIFF documents are often created to take up the entire page. To prevent clipping of the image when you print, make sure Clip = Off is set in the Configuration menu. For best results, try This can be a common situation. TIFF documents are often created to take up the entire page. To prevent clipping of the image when you print, make sure Clip = Off is set in the Configuration menu. For best results, try
Clip = On
Clip = Off
l
TIFF was designed as a file structure for random-access devices. When used as a printer protocol, HP recommends the following ordering restrictions apply to allow sequential processing of the data. These include: · Offset values should be greater than the file position of the offset. For example, If an offset resides at file position A within the TIFF data, its value should be greater than A. · Within a file, all tag fields pertinent to the image should precede the image data. · The ordering of components within each sub-file should be: - Image file directory - Data values identified by directory entry offsets - Image data.
See page 33 for some example TIFF structures.
32 Chapter 3: Technical Reference
Preferred structure of a TIFF file: In Example 1 and Example 2, all the image file directories
occur early in the file. This is a good structure for TIFF files sent to the D640 printer.
Example 1 Example 2
Image file header
II or MM 0x2A00 or 0x002A Pointer to first image file in directory Image File Directory 0 Number of entries Entry # 1 Entry # 2 Entry #3 ... Pointer to Image Data Size of Image Data ... Entry #n Pointer to next IFD Image File Directory Image File Directory Image Data Image Data Image Data

Forward pointers are best
Forward pointers are best
Alternative structure for a TIFF file: In the structure below, the image file directories appear
after the image data. This file may not be printable because of the backward pointer. With this structure, the D640 printer can handle only small TIFF files (one small image).
Image file header
II or MM 0x2A00 or 0x002A Pointer to first image file in directory Image Data Image Data Image Data
Backward pointers might not work. (They are not recommended.)
Image File Directory 0 Number of entries Entry # 1 Entry # 2 Entry #3 ... Pointer to Image Data Size of Image Data ... Entry #n Pointer to next IFD Image File Directory Image File Directory
Chapter 3: Technical Reference 33
Errors
Errors in the TIFF file header or in directory offset values are considered major errors. The remainder of the TIFF file is ignored and the print job is abandoned. For other errors, the processing of the current sub-file continues, but no image is printed. Subsequent sub-files are processed normally. The following are the main categories of errors:
l l l l l l
Absence of mandatory TIFF fields (directory entries) Duplicate occurrences of tags in one directory Wrong type for a significant TIFF field Wrong number of values for a significant TIFF field Value out of range for a significant TIFF field Offset values less than the file position of the offset (for a significant TIFF field)
If a TIFF field is not significant for the printer, its Type, Number, and Value are not checked for correctness. The TIFF specifications (described in TIFF Revision 6.0) require TIFF fields to appear in ascending tag order. The D640 printer does not enforce this requirement. Note You can use the error report setting on the D640 printer to print a report of TIFF errors within a print job. See the D640 User Manual for more information.
TIFF structure and fields
This section includes a full list of baseline and extended TIFF fields with comments on their interpretation by the D640 printer. The following conventions are used to describe the TIFF fields.
l l l
Fields marked with * are significant for the processing of image data by the printer. Fields marked with ** have no default value. These fields are mandatory. If any of these fields are missing from the TIFF data, an error occurs. The first line of the TIFF definition lists the name of the field. The second line provides the tag number in hex, the type of values, and the number values for the field. For example:
Name Tag,Type,N
l
Comments about the field are listed to the right of the field name.

The number of pixels per ResolutionUnit in the horizontal (ImageWidth) direction. If the resolution specified is not the same as the currently selected printer resolution (200, 300, or 600 dpi), the image data may be scaled in the horizontal direction by the ratio of printer resolution to specified resolution. For Group 3 and Group 4 compression modes (compression = 2, 3, or 4), scaling is performed for all ratios, whether scaling up (expanding the data) or scaling down (reducing the data). For uncompressed data (compression =1) or PackBits compression (compression = 32773), scaling down is not performed, and scaling up is confined to ratios 2, 3, 4, 6 and 8. Other ratios are treated as the nearest lower ratio. Ratios less than 2 are treated as 1 (no scaling).

TIFF Images as part of PCL
Introducing PCL compression method 10
The PCL Compression Method command (*b#M) determines how raster data is interpreted for the Transfer Raster Data by Row/ Block command (*b#W). The selected compression method stays in effect until explicitly changed by another PCL Compression Method command (*b#M) or until it is reset by an End Raster Data command (*rC). 42 Chapter 3: Technical Reference
See table below for a list of compression methods. List of compression methods
0 1 2 3 4 5 6 7 8 10
Uncompressed (row-based) Run-length encoding (row-based) TIFF rev 4.0 "PackBits" encoding (row-based) Delta row encoding (row-based) Unencoded (block-based) Adaptive encoding (block-based) CCITT G3 one-dimensional encoding (block-based) CCITT G3 two-dimensional encoding (block-based) CCITT G4 encoding (block-based) Tagged Image File Format (TIFF) rev 6.0 (block-based)
PCL Compression Method 10 is useful when you have a monochrome graphic you want to include as an illustration on a page with PCL text. The actual format of accepted data is described in "Working with TIFF images" on page 29. To include an illustration, transfer the entire TIFF file as a block, including the header. For example, if the TIFF file is 23,476 bytes in size, the raster transfer command would be *b23476W. The TIFF file can be little-endian (from a PC) or big-endian (from HP-UX). Note Only the first image from the TIFF data is printed, any others will be ignored. The image is rendered as the TIFF file describes it, and then the image is clipped (not scaled) to the boundaries specified by the PCL commands for raster width and height. Further, the image will be treated just as any other PCL raster image when used with the Transparency Modes.
Chapter 3: Technical Reference 43
Transparency mode with TIFF

setting the printer's control panel (Copies, Mopies, and Auto-collate) using commands in a print job
For more information on setting the printer's control panel to create multiple copies, see "Printing multiple copies" on page 11. To specify multiple copies in a print job, use the following commands:
Commands for multiple copies
PJL SET COPIES = n Where n is the number of copies specified for each page of a document. Copies are created on a page-by-page basis. Each page is printed n times. See illustration below. Where m is the number of collated copies (mopies) specified for the document. Copies are created on a document-by-document basis. A completed document is printed m times. See illustration below.

This combination of copies and mopies is useful if you're simulating a multi-part form on the printer and you want multiple copies of the form.
File system conventions
The D640 printer now includes the following file system conventions.
Long filenames
The file system for the D640 printer supports a long filename convention similar (but not identical) to long filenames in MS Windows. Long filenames can include any combination of the following:
l l l l
name stems longer than 8 characters (for example, longername.ext) extensions longer than 3 characters (for example, name.grp1) names containing more than one extension or dot "." (for example, name.rev21.tif) names containing special characters (for example, name:new.user or ?name.+)
Chapter 3: Technical Reference 49
Before you create files with long names, consider the following:
l
HP strongly recommends that characters used in filenames be confined to the ASCII printing set excluding characters used as punctuation symbols or wildcards. The following printing characters are excluded in DOS and MS Windows: Operating system
DOS Windows 95 or NT
Excluded Characters . " / \ [ ] : ; | = , ? * + < > " / \ : | ? * < >
The D640 filing system does not enforce these restrictions. However, you may encounter problems when protocol commands refer to filenames with excluded characters.
l l l l l
Files and directories with long filenames have an additional abbreviated name which is DOS-compatible (8.3 characters). In any context, files and directories may be specified by either the long name or the abbreviated name. The limit on a file or directory name (including all extensions) is 100 characters. There is an absolute upper limit of 255 characters on a complete pathname (including drive specifier). Other practical constraints, such as the size of fields on the printer's control panel and in directory listings, should also be considered. In terms of storage space and file access speed, long filenames are significantly less efficient than standard names.
Lowercase in filenames
The D640 printer supports filenames that include both lowercase and uppercase letters. Filenames are no longer converted to uppercase. As with MS Windows, case is not significant for matching names. Two strings which differ only in case are considered to be the same name. (For example, name.ext and NaME.Ext). This rule applies to both standard and long filenames.

Default drive
The default drive is now the printer's internal hard disk, C: (HDD), instead of the printer's floppy disk, A: (FDD). However, this default should not be assumed. A drive specifier should always be included to indicate the internal hard drive. Otherwise, this might lead to incompatibility between printer protocol sent across the network and printer protocol executed from disk.
Documentation updates and corrections
To clarify procedures and examples, this section includes a number of updates and revisions to the D640 Technical Reference Guide (part number C5620-90002).
Commands to read/write to hard disk
You can read, write, and delete files on the printer's hard disk with PJL commands. Reading from mass storage is different for each emulation/personality. Note Currently, there are no security features built into the hard disk filing system. HP does not recommend storing sensitive files on the internal hard disk.
l l l
Files may contain fonts, macros, symbol-sets, user-defined patterns, or ordinary print data. File names can contain up to 100 characters. See "File system conventions" on page 49 for a detailed description. Some file extensions have special meaning on the printer. These include:
.HPG .CRT .PCL .PS .SFS .SFT HP GL2 file Cartridge definition file PCL file PostScript file PCL Softfont in Intellifont form PCL Softfont in True Type form
Chapter 3: Technical Reference 51
Initialize
This command initializes a floppy diskette for use with the D640. Diskettes must already be formatted on the PC in IBM-PC compatible format.
@PJL FSINIT VOLUME = "volume name"
If a password has been set, it must have been given prior to issuing this command.
Make directory on disk
This command creates a new directory on the floppy diskette.
@PJL FSMKDIR NAME="pathname"
where is a fully-qualified pathname. For example:
@PJL FSMKDIR NAME= "C:\PCL5\USER\ACME"
l l
Note
Only one subdirectory can be created at a time, starting at the highest level in the tree. Creating a directory doesn't make it your "current working directory".
Other commands to read/write to hard disk include: FSDOWNLOAD and FSDELETE. For more information on these commands, see "Store a PCL print file on the internal hard disk" and "Delete a file from disk" in the D640 Technical Reference Guide.
Using a disk file in a PCL job
The Alphanumeric ID command reads a file stored on the hard disk or floppy disk. With this command, the D640 reads the file into memory and treats this information as if it was part of the original print job. The result is similar to an "include" statement in a high-level programming language. The D640 does not do any special processing of the file, see "Recommended Contents of Binary Data" in the D640 Technical Reference Guide .
52 Chapter 3: Technical Reference
The format of the Alphanumeric ID command is as follows:
ESC & n # W [ file identification data ]
#
The number of bytes of data that follow the capital W. A value must be supplied.
[file identification data] Byte Content
1 2 ... # Operation Byte (UB) File Identifier Name (ASCxx)
Operation Byte (UB)--The Operation Byte is an unsigned byte, which may have a value 0 through 5. The LaserJet family of printers uses this byte to indicate whether the file contents are treated as a font or as a macro. The D640 does not use this byte, but requires the value to be within the range specified. (The values 0 to 5 are control codes , , , , and .) File Identifier Name (ASCxx)--The File Identifier Name is ASCII data. The D640 requires the full pathname of the file, including the volume name. Files and directories can contain the letters A..Z, a..z, and the numerals 0..9. For example: C:\PCL5\USER\MyFile.pcl. Do not use quotation marks around the filename. Volume
