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,

therefore it is not possible for the Samsung 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.
