In regard to: [cups] backend: open device failed for Laserjet 3010, Harald...:

Are all the printers running recent firmware?  Are the two 3010 printers
configured the same as the other printers that are working?  Correct
network settings and access control settings (if appropriate)?

Does nmap show the same set of open ports on the 3010s as on the working
printers?  There are probably better option sets to use with nmap, but
last time I needed to look at a printer, I used

 	sudo nmap -O -sV -sU -sS printerFQDN

As a debugging point, does it make a difference if you use the hpcups
or PostScript PPD but use the 'socket' backend and port 9100 on the printer?
