HP DesignJet 1050 prints too short

[Noam]

hi all,

Got CUPS (1.1.23-10sarge1) and trying to print out an A0 (841x1189) on an HP DesignJet 1050. I've created a test page in the size of A0 but when I print it the print is about 910mm instead of 1189mm.

Can anyone explain this strange thing? The width of the print is correct as well as the rotation of the print on the paper. I use a roll of paper.

I would be happy to get any tips about this subject.
