Of the two printer files (*.ppd files) in my
/etc/cups/ppd/, one works
and the other doesn't. Doing a "diff" on the two files, I see no
significant difference between them, just things like page size, media
type, and variables related to color.
The one that works is owned by root. The one that doesn't is owned by
lp. Could that be the reason?
Are you sure the one owned by root is the one that works? Mine (10.1)
is owner and group lp.
Also, I'd like to change the name of the working
printer. As far as
I've been able to find, there's no GUI for doing this. Can I just
rename (i.e. mv) the ppd file?
You are using SUSE aren't you? You can use Yast>Hardware>Printer,
KDE Printer Manager, or http://localhost:631/admin
in a browser. And
you shouldn't change the name of the ppd file, as it matches info sent
by your printer to CUPS. The name of your queue is up to you.
And... I'd like to change the *DefaultPageSize:
from A4 to Letter. Can
I just hand-edit the ppd file to do this? And then I'd have to likewise
change *DefaultPageRegion and *DefaultImageableArea and
You might want to give http://linuxprinting.org
a check, and download
the ppd for your printer there. You might miss something. You can also
edit this via any of the GUIs above.
And say I get a nicely working printer and want to
change just a few
minor parameters, like print quality. Could I just copy the working ppd
file and thereby create another printer?
No, I believe this is best done by the particular print dialog box. The
ppd defines what the printer CAN do, you can select what you WANT it to
do per print job via the print dialog box, such as kprinter
Finally (for now anyway), is it permissible to put
comments into a ppd
file, i.e., lines which begin with "*%"?
I wouldn't mess around with the actual ppd file. If you only have one
printer, you should only have one ppd file in /etc/cups/ppd.
