Our local school just purchased a Canon GX7050 printer/scanner.
All clients are running a custom blend of Rocky Linux 8 with KDE from EPEL.
The printer works perfectly so far.
The scanner refuses to work with Simple Scan. Apparently it needs its own
scangearmp2 utility which can be downloaded on Canon’s website.
scangearmp2 from the command line (apparently there’s no corresponding
.desktop file included) the utility can’t seem to find the scanner on the network.
I tested it again by completely disabling FirewallD, and now the scanner is found. So for the moment I added the printer/scanner’s IP address to FirewallD’s
Canon has absolutely no documentation for either its drivers or utilities under Linux. Here’s my question: how do I know which TCP and/or UDP ports I have to open for the
scangearmp2 utility to work correctly?
