Laserjet 1020 not printing on ubuntu12.10

Hi,
Host OS : Ubunu 12.10
Printer : Hp laserjet 1020
Hplip version : 3.13.6
plugin version : 3.13.6

I install the hplip software a few days ago , and it worked well.
Today, i printer some documents as usual, and the papers is not enough, so i just put some more papers in the printer and
power cycle the printer, then the problems come.
The printer never printing again, not print test page too.
And restart the Ubuntu/PC did not help.
When i try to print some page, the Hp manager shows "Task started " "Task completed"....and from the cupsys html page,
i can see the printer is idle, and in good statues, it report no error, and everything seems ok,
but the printer never have a real action. i don't know what happened, what i have done is just powering cycle the printer.

Anyone can help me with this issue ?

By the way, the printer work again after remove the hplip and plugin and re-install it. but i think it is dangerous, sometime, someone power cycle the printer, then it will not work again.

Thanks & Regards.
