What cups-browsed is doing is as soon as avahi-daemon reports an IPP
printer check whether it is a CUPS queue or a network printer and in the
case of a network printer do a get-printer-attributes IPP request. This
does not wake up my printers out of sleep mode. The printers tested here are

- HP Officejet Pro 8500 A910
- HP LaserJet P3005
- HP Color LaserJet CM3530 MFP

Also the printers get polled only once, not repeatedly, either when
cups-browsed starts or when the printer is turned on.
