# Container-friendly CUPS configuration for the Brother HL-4150CDN print server.

# Based on the CUPS 2.4 default cupsd.conf, adjusted so that the daemon
# listens on every interface and allows clients on the local network to use
# and administer the shared printer.
# Log general information in error_log - change "warn" to "debug"
# for troubleshooting...

# Do not register the CUPS "_cups" Bonjour sub-type.

# macOS decides between the driverless AirPrint driver and its generic
# PostScript driver in its Add Printer browser (PMBrowser.framework): it offers
# AirPrint only for a service carrying the "_universal" sub-type, and it treats
# a service as *shared* as soon as it also carries "_cups"
# (-[DNSSDPrinter isShared]; -[DNSSDPrinter airprintMatch] then returns
# nothing). CUPS registers "_cups,_print,_universal" by default, which is why
# the queue is offered as "Generic PostScript Printer" only. Keep "_print" for
# clients that look for it.
