Problem
I am trying to print a document in
Landscape mode, but it prints
rotated and cropped.
Some pages come out all white
(nothing is printed), and I am using
CUPS.
I can't print to an SMB (Windows)
printer.
My application seems to be frozen
while LLPR is running.
How do I specify the IP address of
my SMB server?
Some documents come out as
white pages when printing.
I have CUPS and some options
(such as N-up) seem to be always
enabled even though I don't
choose them in LLPR.
I configured a printer to print to a
file, but I get "Permission denied"
errors.

Possible Cause and Solution
Most Unix applications that offer a Landscape orientation option in their print-
ing 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.
If the data being sent is in Encapsulated PostScript (EPS) format, some earli-
er 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.
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.
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.
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 versions of CUPS, especially those shipped with Mandrake Linux
before the 8.1 release, have some known bugs when processing 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.
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
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.
