I have two HP M1536dnf AIO printers.
Both have been playing up with freezing after printing over the network from a number of Mac OS X 10.7 an 10.8 computers. This can be resolved usually by power cycling the printer.
Now the older one turns on and goes into a blank display screen (backlight is still on) and all status lights are stuck on. The printer is unresponsive and uncontactable over the network.
How can I reset this printer and restore function?
Will this happen to the newer printer too?
