“Limit Check

Problem

Possible 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, and 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 an 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 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 that rely 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 have
exceeded the length of the options and some of

your choices won’t be passed to the programs
responsible for implementing them.Try to select
fewer 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 set to its default
Portrait setting, to avoid unwanted rotations of the
page that would result in 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.
