FWIW, other printers are handled using some other IPC protocol. Same
information sent back and forth, but a different socket and protocol. My
Brother MFC8880 uses IPP and... I forget the name of the other protocol.

Many HP printers can also be handled witout hplip. If you absolutely want
something from HP, the M506dn looks like a fine printer that ought to work
reliably for many years without peculiar host software.
