Hey folks,

okay, here's the situation - I have a Centos 4.2 system with cups printing installed printing via postcript (with appropriate PPD file) to a HP LaserJet 1320N printer (via jetdirect socket 9100).

Everything seems to work right - except for an unusual 'font'??? problem. Many letters seem to be just slightly garbled. At first I thought this was a mechanical problem at the printer (for weeks), but just this morning I took a closer look and realized everything was too regular for it to be a mechanical failure (ink smearing or something).

Anyway the problem is that the bottom non-empty scanline of _very_ many letters/digits/symbols gets transposed over ontop of the topmost non-empty scanline of the same character.

This results in the following conversion (rough ascii art - note there's a lot more scanlines involved due to far higher resolution, which means this is far more invisible).

| AA | | AA AA | | AAAA | | AAAA | | AA AA | => | AA AA | | AAAAAAAA | | AAAAAAAA | | AA AA | | AA AA | | AA AA | | AA AA |

Any idea how to fix this? What could be the problem? How to figure out what could be causing it? It's a very good printer which has no other faults, and it's printing the above characters very crisply... (not that it matter seeing as they are bad...).

Cheers, MaZe.
