Apple LaserWriter 12/640 PS - Manual (Page 97)

What to do next
The printer is now set up on your network.
You don’t need any special software to use the printer. On most UNIX
systems, you use either the
lpr or lp command to print documents over a
TCP/IP network to the printer.
Your printer administrator will generally set up two print queues for the
printer—one to print text files (which must have a carriage return appended
to the end of each line) and the other to print all other files, including
PostScript and PCL files. The names of the print queues typically reflect
which sort of document they’re for.
Examples for lpr
lpr -PGarysLW_text plain.txt
lpr -PGarysLW_raw postscript.file
Examples for lp
lp -d GarysLW_text plain.txt
lp -d GarysLW_text postscript.file
The way you print and choose printing options can differ from one
application program to another. To find out more about printing from your
application programs, read the documentation that came with the programs.
