Go grepping for print_command through your profile's prefs.js.  You 
could write a script and use that for your print command.

Untested, untried, but most likely do-able.

grep print_command prefs.js
user_pref("print.printer_CUPS/Okidata.print_command", "lpr 
{MOZ_PRINTER_NAME:+'-P'}${MOZ_PRINTER_NAME}");
user_pref("print.printer_PostScript/default.print_command", "lp");
