Just got myself a new MacBook Air running Lion, but I can't print to any printers in the office via ethernet. I can see the relevant queues and they also show up in 'Nearby Printers' (Bonjour) but no matter whatever method I try to connect to them, I get messages like: "The printer is not responding. Unable to verify the printer on your network. Unable to connect to xxx.xxx.xxx.xxx due to an error. Would you still like to create the queue?" I've tried pointing the /etc/cups/client.conf file to our print server, which is how our linux desktops are set up. The strange thing is printing to any office printer works just fine on my old MacBook Pro, also running Lion. I took the printers.conf from the linux CUPS server and added in a Canon printer that I have at home). I've copied over the entire /etc/cups directory and restarted CUPS to no avail. The only difference I can think of is that My MacBook Pro is on a slightly different subnet, but nevertheless I've checked that the subnet the Air is on has permission to print. The Air is completely up to date, according to Software Update. No firewall is running. I've had it find an IP address via DHCP and also configured it with a static IP on the same subnet as my Pro. All the office printers are configured with a Static IP and work great for everyone else (who are mostly using Linux desktops and Windows laptops). The ones I most care about are a Xerox Phaser 6360DN and Xerox Phaser 6280DN, especially the latter as it is the nearest to me! I've also tried: - Adding printers indvidually using HP Jetdirect Socket, LPD & Internet Printing Protocols - Alternate drivers for Generic PS Printer and latest versions of drivers from Xerox site - Removing and replacing printer from printer list in Sys Prefs (including numerous 'Reset Printing System' attempts) Suggestions most welcome!
