So, I'm even more confused. I've upgraded again cups-filters (to 1.27.0-2) in
order to do a comparison check, and tried to print, and it did work (with the
Brother PPD, unchanged).
This looks strange, there is no change in the pdftops filter which could
have changed something before the last release.
Or try running the command
driverless
This doesn't return anything. My printer is on the network but I don't think
it advertises itself using Bonjour/zeroconf, so I'm unsure if it'd be enough
for that to find it.
driverless printing is a rather new property in network printers. It
started some years ago with AirPrint to make iPhones be able to print
when connecting to the local network via the WLAN of the router.
Generally printers advertised to print from phones support at least one
form of driverless printing, AirPrint in most cases. Typically the
network printers launched in the last 5 years do driverless but your
printer can be older.
"driverless" lists all IPP printers which support driverless printing.
