Hp laserjet 1020 ( usb device not recognized )!?

I'm not sure, but I think I understand that you're connecting using a USB hub? If so, try connecting it directly to a USB port. Many times an unpowered USB hub does not supply enough power to run a laser printer. Unhook the printer. Go to Printers and Faxes - delete the printer. Hook up directly to a USB port. Let the computer re-install the printer.

Let me know

I have solved this problem, it seems that the cable I used isn't sufficient enough, it was cheap A-B USB cable for printer. I used then the quality cable from my external 3,5" hardrive. I uninstalled all USB related things in device manager, then restarted my computer (just for the case, remove the laptop battery for a while when you are using laptop), then turn on computer, install the laserjet software and then if the message on screen says "connect the printer", do so. Then you should get a messages about correct installing your laserjet and problem is solved :). Good luck, I spent nearly one dat solving this :)

if i delete priter drivers and reinstall is not taking showing error please check cable message showing please check cable now cable is working if i connect other system the same cable is working please give me solution
