Hello John, hello Frank,
thank you for this great ideas. I will try it next time (friday).
I understood the first facility, but maybe you can explain the second one a
little bit more.
1. If I set the printer variable, it accesses the given queue on a local cups
server?
2. If this is so, can the users access the other queues, or only this one?
3. This was a good cause for thought. If you can set the default printer like
this, won't it be possible to install a printer with a script. So that you
don't had any printers before, but in the script are the commands to install
a printer temporary for only one user depending on the terminal name?
Bye
Alex
