inverted image colors

[John M]

All printouts have inverted images... black is white and white is black. Text or certain line art seems to be unaffected. But any kind of bitmap image gets inverted. For example the hp printer test page prints correctly except for the little HP logo image which gets inverted.

Solution: use IJS driver instead of CUPS driver. Then everything prints correctly.

My now WORKING setup using the IJS driver:

openSUSE 11.4 RC1 x86_64
Laserjet p1102w

> rpm -qa "*hplip*"
hplip-3.11.1-5.1.x86_64
hplip-hpijs-3.11.1-5.1.x86_64

[Daniel Morris (danielm-iee)]

This affects openSUSE 11.4 final too, which includes hplip-3.11.1-6.1.i586. I had the same problem with two systems, one an update from 11.3 that migrated the cups/hplip setup and a clean install on a netbook, both when trying to use an HP DeskJet 5150. Using hpijs drivers instead worked. The problem was shown from the hp-toolbox "print test page", whilst the colour wheels were fine, the blue in the HP logo at the foot of the page looked like a negative. Both machines were 32 bit.

I also noted that the second page of a two page (text) document was completely garbled with the default hplip driver. It appeared to be repeating each successive line of text at an offset, like:-

1
21
321
4321
54321 (ie line 5 is over-printed on 4, 4 over-printed on 3, 3 over-printed on 2, 2 over-printed on 1)

Within a few lines the image was unreadable!

[Johannes Meixner (jsmeix)]

The "second page repeating successive line of text" bug
is likely a separated issue which is described as
"Various printout failures with CUPS default RIPCache 8m" at
http://en.opensuse.org/Portal:Printing
I.e.:
Add in /etc/cups/cupsd.conf a line like
  RIPCache 128m
or even up to
  RIPCache 1024m
(the latter if you have at least 2GB main memory in your computer)
and then restart the cupsd should avoid issues because
of the changed banding API in Ghostscript.
