PROBLEM SOLVING
Problem
I am using BSD lpr
(Slackware, Debian, older
distributions) and some
options chosen in SLPR
don’t seem to take effect.
Possible Cause and Solution
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, the length
of the options may be exceeded 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 SLPR 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 (noting 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 SLPR to print, the Printer Package will
work around this issue by converting the data to regular
PostScript. However, if your application by passes SLPR and
feeds EPS data to CUPS, the document may not print correctly.
I can’t print to a SMB
(Windows) printer.
To be able to configure and use SMB-shared printers (such as
printers shared on a Windows machine), 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 SLPR is
running.
Most Unix applications will expect a command like the regular
“lpr” command to be non-interactive and thus return
immediately. Since SLPR 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 SLPR.
