Special Printer Requirements
This appendix describes requirements specific to individual printers.
This appendix describes the following special printer requirements:
l "HP Printers with Flash Memory" (page 69)
l "Lexmark Printers" (page 69)
l "Printers with Automatic Emulation Switching" (page 70)
HP Printers with Flash Memory
If an HP printer has only flash memory, the storing command in the flash memory is the same as if the document was stored
on a hard drive (with this type of printer, the default is the hard drive). If the HP printer has both flash memory and a hard
drive, you can use either one or the other storing command, according to your needs.
Lexmark Printers
Set a Port for Binary Mode on the Optra+/Optra S
On the Optra +/ Optra S printers, you can set binary mode by changing a printer device parameter in order to accept binary
data. Specifically, you can set the /Filtering parameter to /None. This means that <CTRL+D> and other values will be passed
to the PostScript interpreter as data instead of commands. The device parameter resides in non-volatile RAM, so you only
need to send the file once. The following are samples of PostScript files that cause the printer to switch the port from ASCII to
binary mode.
To set a parallel or INA port for binary data:
1. To switch to binary mode, enter the following (ASCII off):
%!PS
true 0 startjob
currentsystemparams /CurInputDevice get
<< /Filtering /None >> setdevparams
2. To switch to ASCII mode, enter the following (Binary off):
%!PS
true 0 startjob
currentsystemparams /CurInputDevice get
<< /Filtering /InterpreterBased >> setdevparams
Note that these files are port specific. Thus if you send the files to the printer using its parallel port, only the parallel port is
affected.
