[Lilux-help] postscript printing problems with suse 9.1

greetings, i installed my printer (hp laserjet 1200 on a router with print server) with yast ( "Geraete-URI: Gefilterte Weiterleitungswarteschlange nach HP auf LPD-Server 192.168.0.1) and printed a test page using text and a picture, and it worked perfectly. also printing from openoffice works like a charm. but when i try to print a .ps file, instead of the document, i get a printed error message: "the postscript interpreter in your printer is 2014.116. this printout requires at least version 2015 or greater." it goes on recommending to change the output to basic level 2. does anyone know this error message, or how to configure the printing system to use level 2? best regards, kymon
