lpr gui dialog box popping up from command line printing.

[dochawk]

I have a script that loops to merge and print files; I run it from an xterm. It used to work before I switched to a mac.

On a new install, though (amd64), it's popping up an LPR GUI dialog box on every single iteration of lpr.
This is merely annoying when there are three or five jobs, but I'm looking at 70 this week.

The command is

lpr -o sides=two-sided-long-edge printme.pdf

(where the script already generated printme.pdf)

The output is,

**** Unable to open the initial device, quitting.
Package `cupsys-common' is not available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

Re: lpr gui dialog box popping up from command line printing.

I've fond the answer, after much googling.

I think it's the samsung unified printer that does it, but the standard installation moves lpr to lpr.orig, and lpr itself is actually a link to that lpr_gui program--with the result that it is impossible to print with lpr in a console, and batch use of lpr is unworkable.

I manually undid thes links to get it working as expected.
