Printer Setup, Software & Drivers

My printer has been printing without problem from various devices in my home network without problem and suddenly stopped.

In the print queue, "Printing - unable to get printer status" is displayed.

I initially went through all of the usual - rebooted the computer, printer, and router. In system preferences, the printer (before printing) has a green dot in front of it.

I went to the ip address of my printer in my browser and pulled up the web page. It is clearly connected - it has all of the info, supply levels, ip addresses, network names, etc. If I try and print a test page (e.g the configuration report from the printers webpage), the printer displays an error 49 then reboots.

If I try to print a testpage from the print queue, it displays ready to print, printing, connected to printer, then unable to get printer status" and just sits there. The printer icon now will have a yellow dot in system preferences instead of a green dot.

Looking both on the printer's screen and on the printer's web page, all of the info is correct (e.g. same wifi network, etc).

And it was printing a few days ago.

-- so the next thing I did was reset the mac printing system deleting the printer. I downloaded the current HP software and "easy installed" the printer and scanner. No complications.

For the test scan - it worked and scanned the document so clearly the computer and the scanner are connected via the network.

For the test print - same problem - hangs at unable to get printer status.

Any ideas?
