1. I have an AirPrint-enabled printer on the network (an HP ENVY 4502)
and a CUPS server too. The cups service on the server is stopped. A
client computer has had the lpd, socket, usb, snmp and dnssd backends
disabled using 'dpkg-reconfigure cups'. ippfind gives
ipp://envy4500.local:631/ipp/print
A script on the client has run the commands ippfind, driverless and
lpinfo -v 50 times on the run. The success rate for ippfind and
driverless is 100%; lpinfo -v averages at 96%-98%.
2. cups was now started on the server. ippfind gives
ipp://desktop.local:631/printers/Colour
ipp://desktop.local:631/printers/LaserJet-300
ipp://desktop.local:631/printers/DotMatrix
ipp://desktop.local:631/printers/DotMatrixT
ipp://desktop.local:631/printers/qqq
ipp://desktop.local:631/printers/rawq
ipp://envy4500.local:631/ipp/print
The success rate for ippfind when the script is run is 75%. For
driverless it varies from 24% to 64%. For lpinfo -v it is 66% but
it has been seen to be as low as 8%.
The success rate for ippfind can be increased to a consistent 100%
by using 'ippfind -T 5' but there is nothing similar which can done
for driverless as it stands.
