Driverless sounds like a nice concept, but doesn't seem to work for
me. I
deleted the proprietary printer driver for my brother laser hl-
l2395dw,
then on KDE try adding a printer. It does detect the printer in the
"discovered printers" section I see a hll2395dw "driverless"
option.
But
if I choose that, I'm prompted to fill in an ip address and some
other info
(port?). So I don't think this is actually working. Choosing
instead
Brother's proprietary driver works and connects via dnssd without
asking me
for other info.
See my earlier remark about Avahi. If Avahi is working, it shouldn't be
necessary for you to specify an IP address, but I've found that very
occasionally I need to give it a kick after a reboot or software
update, using the 'avahi-browse' command noted previously. Here's a
screenshot of the Add Printer dialogue in KDE/Plasma. The selected line
is the one that uses Avahi.
