Hello there,
I am trying to run OMV as an OS on a Raspberry Pi, mainly for printer sharing and light file storage.
I tried to use OMV's web interface to add this printer, then I remembered its driver was not included in the default CUPS configuration. Since it was previously installed on the Mac, I found the .ppd file, logged in CUPS web interface, and tried to upload the found PPD, but it ended up in an error "Broken pipe". What is the proper way to add a PPD file from the Web interface, if there's any?
