No response from my HP LaserJet 2420d

I've just tried to connect my new HP LaserJet 2420d to my iMac (one of the new Intel ones) and have installed the appropriate software. However, when I click on print (from any application). It goes through all the motions on screen, but nothing comes out of the printer. It doesn't even wake up. When I go to the Printer Queue window, it shows me that there are no jobs pending and that the job I just submitted is now in the 'Completed' list. Incidentally, although I can see the printer in my 'printer setup' window and attached to the USB port in the system profiler, when I open the 'hp printer selector' application, no printer is shown. I have also tried downloading the latest hp driver from the hp website to no avail. Any suggestions?
 
Incidentally, I've tried installing the driver suggested in one of the other threads (hpijs/ESP) and although it installs nicely, it doesn't seem to make any difference.
 
Did the printer show up when you did ADD in Printer Setup?
Did you connect (or not) the printer as recommended in the manual when installing the software?
Does the printer show up in System Profiler?
Did you repair permissions (Disk Utility) after installing HP software, then restart before trying? (HP installers are infamous)
 
Thanks gshali! The answer to the first three questions was yes, but repairing the permissions worked a treat! Printer seems to be fine now. What does this 'repair' actually do then?

cheers

Repairing permissions is primarily to fix ownership/access rights in the underlying unix system folders and files. To install some files, the installer has to use root/superuser permissions - but then those need to be set to allow everyone (like the special CUPS print system user) permission to access/execute.

Short version - it's a unix thing.
