Subject: Re: [newbie] Printer Problems M9.0 and Lexmark Z53


No, the colours are all there, printer works fine in M8.2, not M9.0

but I have found out something.

the ghostscript drivers for M8.2 are a different version to M9.0
for instance
M8.2 uses one ghostscript driver, LEXMARK Z52,CUPS+GIMP-print v4.2.0
M9.0 LEXMARK
Z53,CUPS+GIMP-print v4.2.2

so what, I here you say,

well hithertoo I have done testpages for all 3 ghostscript drivers which
appeared ok, the colour wheel was good and the colours were vivid enought
with everything just so, until you take a closer look at the colour wheel
pie chart lettering, I guess I must of been hasty to say the test page
looks fine, because upon closer inspection, whilst:-

yellow is in pie chart position against Y , that's ok
one shade of red " C , I take to mean crimson
yet another shade of red " G , which surely ought to
mean green
green is in pie chart position against R, which surely ought to mean
red blue is in pie chart position against M, which I take to mean
mauve purple is in pie chart position against B, which I take to mean
blue


I would have guessed Y yellow, C cyan, G green, R red, M magenta, B blue.

I stand corrected,

but the fact of the matter is that

yellow is in segment for Y yellow
blue - " - M magenta
red _ " _ C cyan
mauve _ " _ B blue
red _ " _ G green
green _ " _ R red


which means the red and the blue primary colours are cross wired
somewhere, either in the driver in which case it is in all three
ghostscript drivers, and across two ghostscript versions, or
as seems more likely it's in the spooling control mechanism.

Now kde have added to their programme,
kde CC - system - printing manager - settings , besides their old tabs
of general, HP-GL/2,and driver settings , two new tabs for :-

Image : here a little picture is displayed and 4 colour settings
brightness, 100

hue(colour rotation) 0

Saturation 100

Gamma 1000

these are all the default

there are also some contols for image position and image size


I'm guessing, but my money is on this software being screwed.

It's not really a new programme it's been around before and
at one time was part of qtcups or kups, which are no longer
completely available and I believe the intergration into kde
in this programme has a glitch in it which has the effect of cross
wired blue and red . That's my current theory. It seems
like a sound one at the moment, but I don't entirely rule
out driver error.
