 == How to find out whether my printer is capable of driverless printing?
 
-* look for AirPrint among device specification
-* https://www.pwg.org/printers/[Officially certified printers for IPP Everywhere]
-* check xref:_how_to_setup_cups_temporary_queues_with_network_printer[manual] for enabling CUPS temporary queues - if your printer is seen in the end in CUPS commands that way, your printer is capable of driverless printing
+Network printers have the prerequisites - enablement of IPP port on the printer is the minimum, mDNS is required for automatic printer discovery by `libcups`.
+
+* [command]`ipptool` command which sends IPP Get-Printer-Attributes request to the network printer passes:
