Common Linux Problems
ProblemPossible Cause and Solution
I can’t change settings in 
the configuration tool.You need to have administrator privileges to be able to change 
global settings.
I am using the KDE 
desktop but the 
configuration tool and 
LLPR won’t start.You may not have the GTK libraries installed. These usually 
come with most Linux distributions, but you may have to 
install them manually. Refer to your distribution’s installation 
manual for more details about installing additional packages.
I just installed this 
package but can’t find 
entries in the KDE/Gnome 
menus.Some versions of the KDE or GNOME desktop environments 
may require that you restart your session for the changes to 
take effect.
I get a “Some options are 
not selected” error 
message while editing the 
printer settings.Some printers have conflicting settings, meaning that some 
settings for two options can’t be selected at the same time. 
When you change a setting and the Printer Package detects 
such a conflict, the conflicting option is changed to a “No 
Choice” value. You have to choose an option that does not 
conflict before being able to submit the changes.
I can’t make a printer the 
system default.In some conditions, it may not be possible to change the 
default queue. This happens with some variants of LPRng, 
especially on recent RedHat systems that use the “printconf” 
database of queues.
When using printconf, the 
/etc./printcap file is 
automatically refreshed from the database of printers 
managed by the system (usually through the “printtool” 
command), and the queues in 
/etc./printcap.local are 
appended to the resulting file. The default queue in LPRng is 
defined as the first queue in 
/etc./printcap, therefore it is 
not possible for the Linux Printer Package to change the 
default when some queues have otherwise been defined using 
printtool.
LPD systems identify the default queue as the one named “lp”. 
Thus, if there is already a queue by this name, and if it 
doesn’t have any alias, then you won’t be able to change the 
default. To work around this, you can either delete the queue 
or rename it by manually editing the 
/etc./printcap file.
The N-up setting does not 
work correctly for some of 
my documents.The N-up feature is achieved through post-processing of the 
PostScript data that is being sent to the printing system. 
However, such post-processing can only be adequately 
achieved if the PostScript data conforms to the Adobe 
Document Structing Conventions. Problems may arise when 
using N-up and other features relying on post-processing if 
the document being printed isn’t compliant.

I am using BSD lpr 
(Slackware, Debian, older 
distributions) and some 
options chosen in LLPR 
don’t seem to take effect.Legacy BSD lpr systems have a hard limitation on the length 
of the option string that can be passed to the printing system. 
As such, if you selected a number of different options, you 
may exceed the length of the options and some of your 
choices won’t be passed to the programs responsible for 
implementing them. Try to select less options that deviate 
from the defaults, to save on memory usage.
I am trying to print a 
document in Landscape 
mode, but it prints rotated 
and cropped.Most Unix applications that offer a Landscape orientation 
option in their printing options will generate correct PostScript 
code that should be printed as is. In that case, you need to 
make sure that you leave the LLPR option to its default 
Portrait setting, to avoid unwanted rotations of the page that 
would result in a cropped output.
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 the 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 SPL) 
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 at fault probably, contact your 
software vendor to inform them of the issue.
Some color images come 
out all black.This is a known bug of Ghostscript (until GNU Ghostscript 
version 7.05) when the base color space of the document is 
an 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 the recent Ghostscript at www.ghostscript.com.

the installation type. 
The window provides two options for software installation:
•Easy Install (recommended method): This option loads 
the PPD file and the Adobe Acrobat Reader programme. 
•Custom Install: This option allows you to choose which 
components will be installed, the PS Level 3 PPDs and the 
Adobe Acrobat Reader programme for opening the User’s 
Guide.
