Hi, I am an absolute beginner with LinuxLite but I have already learned that if I Enable the FirewallD, I then cannot get the default 'Document Scanner' software to see my network connected scanner (part of an Epson WP-4545 MFU). This connection works fine if the firewall is Disabled, but I would like to know how to set the firewall to allow the scanner to work with it Enabled, please.
I have found the guidance on configuring the firewall in the Help Guide, so I know I should set the Configuration to 'Permanent' and the Zone to 'Home', but I have no idea what 'service(s)' the 'Document Scanner' uses. I guessed that it would be 'sane', but when I checked that 'service' for the 'Home' zone and reloaded the firewall it made no difference when I tested the scanner connection; - Document Scanner reports "No scanners detected; Please check your scanner is connected and powered on" (even though it is). Clearly this problem is caused by my inability to configure the firewall to all the scanner through...
Advice please?
Also, I tried to install the Epson 'ImageScan! for Linux' scanner driver for this WP4545 machine (there is a driver dated 2019). So far it does not work, and reports "Could not send command to scanner. Check the scanner status", even with the Firewall disabled so that 'Document Scanner' *can* connect to the scanner. The installation instructions say that SANE must be preinstalled; - is SANE installed by default in the Linux Lite distribution?
