6-42 Configurationbb ______________________________________
Selecting PostScript or Emulation Modes
The printer’s front panel allows you to select modes (Adobe
PostScript or an emulation) through the Interface menu, SETUP:I/F.
For details on selecting the interface, see “Selecting Menu Options”
earlier in this chapter. Then see “Interface Control” in this chapter
for listings of modes available for each interface port.
The main ways to configure a printer interface are for
• PostScript only files • HP–GL only files
• HP PCL 5 only files • A mix—PostScript and HP PCL 5 files
Each port can be individually configured. For example, you can
configure the parallel port for PostScript and the serial port for HP-GL.
If you plan to send a combination of PostScript and HP PCL 5 files,
you may want to set at least one of the printer interfaces to an
automatic switching mode. This Automatic Interface Switching
(AIS) technology works by examining the incoming data stream to
determine if it is a PostScript or HP PCL 5 file and then by activating
the appropriate emulation.
Automatic switching is designed to work with mainstream
application packages. Occasionally, some applications do not use the
customary codes at the beginning of a file, and the file may not work
as expected. If this happens, use the front panel to set the printer to
the appropriate emulation.
Note: If you are printing in either PCL 5 or HP-GL 7475A mode,
see appendix A, “HP PCL and HP–GL Supported
Commands,” for details on PCL syntax and commands.
