HP 1020 stops working after switching off and on. [ubuntu]

I installed HP1020 as per the instructions. It works perfectly.

But when I switch it OFF and ON (Power supply) while computer with UBUNTU is on, it stops working. It shows in CUPS Printer list but it does not print.

I removed the printer from printer list. Restarted the computer. Re-plugged the USB cable. And made fresh install in CUPS.

Now the printer is working.

$ usb_printerid /dev/usb/lp0
GET_DEVICE_ID string:
MFG:Hewlett-Packard;MDL:HP LaserJet 1020;CMD:ACL;CLS:PRINTER;DES:HP LaserJet 1020;FWVER:20050309;

I switched OFF the printer and switched ON. But this time the printer is still working. Earlier couple of times switching it OFF and ON stopped it from working.

I thing I had notices when printer is not working that /dev/USB folder goes missing.

I will post $ usb_printerid /dev/usb/lp0 output when my printer stops wotking again...

HI

I had to switch off the printer for cleaning and when I switched it on. It stopped working.

Here is the output
$ usb_printerid /dev/usb/lp0

Error: Input/output error: GET_DEVICE_ID on '/dev/usb/lp0'
