strange cups problems

[Duke42]

cups-1.1.18-r4, ghostscript-7.05.6, gimp-print-cups-4.3.8-r1

Now, I don't get this:

I have cups, ghostscript and gimp-print-cups installed and the test page comes out just fine. But when I try to print something (ps or txt) I get a space half of page big between each line!
Plus: cups thinks the page is ready then - I mean: it doesn't try to print 60+ pages.

Has anybody seen this? perhaps a clue?

Also: it seems that the test page is a ps file. Why won't cups print other ps files as well?

byw, Duke42.
