It sounds like you have tried all the right things and are on the right track.

(You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure)

here are a couple of simple suggestions to try for a quick fix

Try this...
Rollback or update your driver
Click on Start, open Printers and Faxes then push the F1 key on your key board.
This will open the Help and Support Center.
Now type in drivers in the search bar, this should bring up most of the information you need to update your printer drivers.

Not getting anywhere...
Try this... Unplug the printer and any other additional device connected to your PC.
Check that you have the original installation CD for the printer, then
Uninstall all the printer software

Restart your PC and DO NOT plug the printer back in yet.
Install the printers software from the CD.
It should get to a stage in the installation and ask you to plug the printer in, do this now. after that just follow the instructions on the screen and you should be up and printing again.
You may need to restart your computer after installation is complete, its OK to leave the CD in the player (unless you are instructed to remove it) and leave the printer plugged in at this stage.

There are a lot of variables, other options and other ways of doing this, so if you have the patience keep reading up on it and trying different things.
good luck

Hi, when I try to print to a networked GK420t, it prints the first page then feeds two and a half labels and then flashes a red light. At which stage it completely loses network - pings time out.


The problem that you are facing can be resolved by doing a reset on the printer and then setup the printer on the network again. This will resolve the issue.
