Common Linux Problems

Problem

Possible Cause and Solution

I can’t change settings in 

the configuration tool.

You need to have administrator privileges to be able to affect 

global settings.

I am using the KDE 

desktop but the 

configuration tool and LLPR 

won’t start.

Maybe you do 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, and 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. Since the default queue in LPRng is defined as the first 

queue in /etc/printcap, 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, 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 Structuting Conventions. Problems may arise when 

using N-up and other features relying on post-processing if 

the document being printed isn’t compliant.
