Maybe, it is not much typical but the user really need not have a printer and he
should not be bothered by warnings about it each time he starts OOo. I think
that it is  enough to print error messages if he tries to print and he does not
have the printer tools tools installed.

Actually, OOo prints the following messages on start up if the printing stuff is
not installed:
sh: line 1: /usr/sbin/lpc: No such file or directory
sh: line 1: lpc: command not found
sh: line 1: lpstat: command not found

In addition it prints the following message if the user tries to print with the
Generic Printer:
sh: line 1: lpr: command not found


I will attach a patch which removes the messages on start up.

In fact, it would be better to do show an error dialog if the user tries to
print and the printing stuff is not available. The messages printed to stderr
are not visible if OOo is started from a menu or an icon on a desktop.
