I have been printing to a Brother DCP 150-C from my Mac, with the printer plugged into my linkstation. Following upgrade to os 10.7, it no longer works. Previously, when I printed to printer 'lp' I had the option of printing as 'Guest' this option has disappeared and it now asks for an identity. I have tried both Guest and blank password, and user 'admin' and password 'password', and my Mac username and password in these fields, none of which have had any success.
The job appears in a print queue, but with the printer paused, and when I resume printer it says 'unable to connect to printer'. Driver version is 4.1.0, though as the printer and this driver were working together before I don't think this is the problem. I have upgraded my firmware to 1.56 already, and tried all the obvious rebooting everything and uninstalling/reinstalling the printer.
Everything else seems to be working normally as it was before the upgrade.
