Printer configurations
The HP LaserJet 1160 printer is only available in the base configuration.
The HP LaserJet 1320 Series printer is available in several configurations. The letters that
follow the printer name indicate the differences between the configurations. Each letter
refers to a specific feature. Use the information in this section to determine which features
your model has.
Table 1-1. Feature designations for HP LaserJet 1320 Series printers
Printer Model Description
HP LaserJet 1160 This is the base model. It includes an IEEE-1284B parallel port and a
universal serial bus (USB) port.
HP LaserJet 1320 This is the base model. It includes an IEEE-1284B parallel port and a
universal serial bus (USB) port.
HP LaserJet 1320n The printer includes the same features as HP LaserJet 1320 with an
internal HP Jetdirect network port instead of the IEEE-1284B parallel port
HP LaserJet 1320tn This printer includes the same features as HP LaserJet 1320n and adds a
250-sheet input tray.
HP LaserJet 1320nw This printer includes the same features as HP LaserJet 1320t and adds
integrated 802.11b/g wireless connectivity.
