Lightbulb CUPS - margins and rastr


There are two printing problems in this thread:

1. This seems to be a common problem with CUPS: printers do not correctly center print-out on page.
2. Character of image rendering.

I searched the linuxprinting,org for help in vain.

CUPS v.1.1.19
printer HP Desk-jet 9650 (non-postscript, afaik)
Driver: Foomatic+hpijs
PPD for HP 9600 was downloaded from the
PPD for HP 9650 doesn't seem to exist.

Installation and configuration went well, after reading the manuals and howtos.

oowriter is now "PPD aware". The quality of print is great.
The only problem is that the print is so badly off-centered that I can't use the printer at all.
Too bad. and alignmargins downloaded from did not help.
I tried to mess up manually the ppd files, but original files are restored as soon as I re-load the oowriter. This made me slightly mad.

Does anyone have an idea?
2. Another question is about the character of rendering of images on page (this question might be interesting only for Ink-Jet users).
Images and backgrounds can be rendered in two ways:

a. ink spread evenly, or
b. ink organized in fine dots and lines like on most laser postscript printers.

In case "b" your prints look (nearly) as cool as if they were printed on one of those coolest machines usually used in press and professional publishing. In case "a" they look normal, like you print them on a cheaper (doesn't mean bad) machine.

I partly got effect "b" by using a generic PCL driver suggested by CUPS. The problem was that the printing was terrific slow. Is there a way to adjust an existing good PPD in /usr/share/cups/model/ so that it changes the character of rendering? I hope my last question is clear.

Just guessing, but try gzipping your modified PPD file (say it was hpijs-modded.ppd) and placing it in /usr/share/cups/model. Then run
lpadmin -pName_of_printer -P hpijs-modded.ppd.gz
No idea about the character rendering question.
