I have a " .ps" file generated from an application on Solaris 2.4. When I sent the file to printer by issuing "lp" command, it just treat the .ps file as an ASCII file and printed the contents of the file! The system admin told me the HP printer has been set to support postscript file. Does anyone can help me to find does the HP printer indeed support Postscript file? and if so, howw do I print PostScript file in Solaris 2.4?
