After a overnight apt-upgrade our printer has ceased to function. The parallel port inkjet printer itself has been checked and found to be OK.
We've tried removing/re-installing the printer via the KDE Printer Wizard with some peculiar results.
ie. In the Backend Selection page we selected "Local Printer" but the Local Port selection fails to detect a valid port.
We've tried manual entry of the URI using both parallel:/dev/lp0 and ipp://localhost:631/printers but both are rejected as not corresponding to a detected port.
If we ignore this error and insert one of the above in the URI we can select our printer and are prompted to select from a list of drivers. But some drivers are reported as missing or we don't have the required permissions although we are root. Selecting a driver, that past experience has shown we can use, allows completion of the printer installation. But the printer still does not print.
Doing lsmod reveals that both lp and parport modules are loaded. Also cupsd appears to be running.
ps My apologies if this mail has appeared several times on the list. I think my ISP has been having problems and has been sending mail back as unsent. Furthermore mail I have sent to the list in not appearing in my inbox. Hopefully this has now been resolved.
