These three files (printcap, magic_ljet4_filter, and runlatex) are used, together with utilities mentioned in the "printcap" file, to allow PC users on a Novell LAN to submit LaTeX jobs for printing, without having access to LaTeX itself. The idea is to avoid maintaining more than one LaTeX setup, if LaTeX is only occasionally used by some people on the LAN. The scripts are new even to us, and have not been extensively tested. No guaranties, no promises. Good luck!
