How do I specify the
IP address of my SMB
server?
It can be specified in the “Add Printer” dialogue of
the configuration tool, if you don’t use the CUPS
printing system. Unfortunately, CUPS currently
doesn’t allow you to specify the IP address of SMB
printers, so you will have to be able to browse the
resource with SAMBA in order to be able to print.
Some documents
come out as white
pages when printing.
Some versions of CUPS, especially those shipped
with Mandrake Linux before the 8.1 release, have
some known bugs when processing PostScript
output from some applications. Try upgrading to the
latest version of CUPS (at least 1.1.14). Some RPM
packages for the most popular distributions are
provided as a convenience with this Linux Printing
Package.
I have CUPS and some
options (such as N-
up) seem to be always
enabled even though I
don’t choose them in
LLPR.
There may be some local options defined in your ~/
.lpoptions file, which are manipulated by the
lpoptions command. These options are always used
if not overridden by LLPR settings. To get rid of all
options for a printer, run the following command,
replacing “printer” with the name of the queue:
lpoptions -x printer
I configured a printer
to print to a file, but I
get “Permission
denied” errors.
Most printing systems will not run as the super-user
but as a special user (usually “lp”). Therefore, make
sure that the file you have chosen to print to is
accessible to the user owning the spooler daemon.
On my PCL (or GDI)
printer, I sometimes
get error messages
printing instead of my
document.
Unfortunately, some Unix applications may generate
non-compliant PostScript output that may not be
supported by Ghostscript, or even the printer itself
in PostScript mode. You can try to capture the
output to a file and view the results with Ghostscript
(gv or ghostview will allow you to do so
interactively) and see if you get error messages.
However, since the application is probably at fault,
contact your software vendor to inform them of the
issue.
Some color images
come out all black.
This is a known bug in Ghostscript (until GNU
Ghostscript version 7.05) when the base color space
of the document is indexed color space and it is
converted through CIE color space. Because
Postscript uses CIE color space for Color Matching
System, you should upgrade Ghostscript on your
system to at least GNU Ghostscript version 7.06 or
later. You can find recent Ghostscript versions at
www.ghostscript.com.
