Printing problems

Hi, I am having a problem setting up printing on my daughter's computer, which is running Debian/lenny. She got an HP Deskjet 3050 wireless printer, and CUPS sees it just fine, however, when I try to print a test page from cups, it says Unsupported format 'application/postscript'! However, whenever I try to print a test page from within Trinity, using kcontrol -> Printers, I get the following message: A print error occured. Error message received from system: cupsdoprint -P 'HP_DJ_3050' -J KDE Print Test' -H '127.0.0.1:631' -U 'user' -o 'multiple-document-handling=separate=documents-uncollated-copies orientation-requested=3' '/opt/trinity/share/apps/kdeprint/testprint.ps' " execution failed with message: successful-ok Any idea whats going on here and how to fix it? My other problem is that I don't have physical access to the box, only over secure connection. Thanks, --b
