GK420d prints everything as text

Attempting to send epl appears to 'break' the printer. I have two printers that were both cheerfully printing ZPL using a windows generic text driver, that now will only print whatever is sent to it as text - this includes reset commands sent from the set up utility and an attempt to update the firmware resulted in the machine printing out the contents of the binary. A factory reset from the line feed button also has no effect. Does anybody have any ideas as I now have two machines that are effectively 'bricked'. A snippet of the epl that I sent to the machine is :

Q822,24

Please use ! U1 getvar

Please use ! U1 getvar "device.languages" to check what the printer language setting is on the printer. Most likely, it was accidentally set to line print mode. If it is line print mode, we need to use ! U1 setvar "device.languages" "epl" to set it back to EPL if we want to print EPL.

Hi Steven,If from the Zebra

Hi Steven,

If from the Zebra Setup Utility, from the 'Open Communication With Printer' window I enter ! U1 getvar "device.languages" in the top  text area, when I click Send To Printer, the machine just prints the string ! U1 getvar "device.languages". Likewise for ! U1 setvar.

Then you could use Zebra Setup Utility -> Configure Printer Settings to set the printer language.

Hi Steven,there is no option

Hi Steven,

there is no option to change the printer language that I can see. There is a ZPL Mode which is set to ZPL II.

Any suggestions as to how I

Any suggestions as to how I take the machine out of line mode, if commands such as ! U1 getvar "device.languages" are interpreted as text and just printed rather than effecting a change ?
