Setting up a USB laserjet samsung ml1710 on a dell desktop under FC5. I used the sstem-config-software graphical interface. At the end, the test
page printed fine. All seemed to go as per instructions in reference text.
However if I try to print a file (as root or as user) I get a bash permission
denied reply. Checkind permissions in /usr/bin/lpr or lp, it appears permissions
are set at rwx for all. I find /dev/ttyS0 as -I think- location of printer.
Any suggestions? I have an earlier request in, but that one followed a quite different set-up path, and did not print the test page. The printer seems linked, given the test page- why permission denied on lp and lpr?
Thanks- Marshall Blann
