Umm, Im not sure what you mean here. You mean the command line options that are available to me or the command line option that I use when I type the lp command?
Well, the command line options available to me are just the standard CUPS command line options on a Debian unstable box (shouldnt be any different then on any other box).
The comand line option that I use when typing the lp command is just -dojs where -d specifies the destination of the spool to use and ojs is the name of the spool I created with the CUPS web interface. So the full command line is
lp -dojs somefile.ps
Thanks for your help by the way, I havnt had much success in getting help anywhere else, even on the CUPS forums.
