AFPL Ghostscript v. 8.52 or above. Download the latest version of AFPL Ghostscript from http://sourceforge.net/
projects/ghostscript/ and install it to solve this problem.
I cannot scan via Gimp
Front-end. Check if Gimp Front-end has Xsane:Device dialog. on the Acquire menu. If not, you should install Xsane plug-in
for Gimp on the your computer. You can find Xsane plug-in package for Gimp on Linux distribution CD or Gimp
home page. For the detailed information, refer to the Help for Linux distribution CD or Gimp Front-end
application.
If you wish to use another kind of scan application, refer to application’s Help.
“Cannot open port device
file” error message
appears when printing a
document. Avoid changing print job parameters (e.q., via LPR GUI) while a print job is in progress. Known versions of CUPS
server break the print job whenever print options are changed and then try to restart the job from the beginning.
Since Unified Linux Driver locks the port while printing, the abrupt termination of the driver keeps the port locked
and unavailable for subsequent print jobs. If this situation occurs, try to release the port by selecting Release port
in the Port configuration window.
