HELP! My printer won't stop!!

["Vegard Lundby Rekaa" <vegardlr@student.matnat.uio.no>]

I used the lpr command to print an image, which gave me great problems.
The printer writes text on every 4th page saying:
%!PS-Adobe-3.0
          %%Creator: The X Print Server's PostScript DDX (xprint.mozdev.org)

I tried deleting the printer with 'localhost:631' and 'apt-get --purge
remove cupsys', yet every time I start my PC the printer start again.

Help! What can I do?

Best regards, with hopeful wishes from Vegard!
