I am told I am not authorized to change the Media Size (from letter to A4). In fact it is worse if I run as root, since I cannot leave the program - I have to kill it from another console. > Doesn't launching hp-setup from a root terminal work? As far as I can see, hp-setup only allows me to install a second printer, not to modify an existing one. I should perhaps have made clear that the CUPS web interface does allow me to change the media size; my remarks were only addressed at system-config-printer. Incidentally, I was trying to discover where the page size (letter or A4) is stored on the computer. I couldn't find any mention of it in /etc/cups, /var/spool/cups or /var/run/cups . -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
