Solving Problems

7.18

Some pages come out 
all white (nothing is 
printed), and I am 
using CUPS.

If the data being sent is in Encapsulated PostScript 
(EPS) format, some earlier versions of CUPS (1.1.10 
and before) have a bug preventing them from being 
processed correctly. When going through LLPR to 
print, the Printer Package will work around this 
issue by converting the data to regular PostScript. 
However, if your application bypasses LLPR and 
feeds EPS data to CUPS, the document may not 
print correctly.

I can’t print to an SMB 
(Windows) printer.

To be able to configure and use SMB-shared printers 
(such as printers shared on a Windows printer), you 
need to have a correct installation of the SAMBA 
package that enables that feature. The “smbclient” 
command should be available and usable on your 
system.

My application seems 
to be frozen while 
LLPR is running.

Most Unix applications will expect a command like 
the regular “lpr” command to be non-interactive 
and thus return immediately. Since LLPR is waiting 
for user input before passing the job on to the print 
spooler, very often the application will wait for the 
process to return, and thus will appear to be frozen 
(its windows won’t refresh). This is normal and the 
application should resume functioning correctly 
after the user exits LLPR.

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
