How can I achieve the following behavior?

  1. CUPS Server communicate with hardware printer by using the "PostScript3" language and the LPD/LPR protocol to manage and transmit printing jobs.

  2. CUPS server must be configured to accept following file formats: PS, TXT, PDF, JPEG and PNG. This means only these files get printed and others should be blocked.

  3. I want to connect actual hardware printer using IPP from the linux machine.

CUPS has no knowledge of the file formats being printed. It receives data in PostScript or text format and sends it along to a printer. It is impossible to restrict based on file format at that level. – Patches Jun 24 '11 at 15:07
Any reason to prefer PostScript3 over Postscript2, which was developed in 1991? (my point being that most printers purchased since Y2k use version 3 anyway, which was created in '97) 3 is a little ambiguous (LAN printing?). And also, @Patches, CUPS actually converts images before sending them off (see the Filters Section) – new123456 Jun 24 '11 at 15:41
but my question is that,Can i set language=PostScript3 in any cups confige file. – yogesh Jul 6 '11 at 9:08
