The biggest problem is not using the correct printer driver and not setting the page size correctly.
Printer drivers can be obtained from either Zebra or Seagull Scientific. The Zebra ones are fine for standard paper sizes but you should consider the Seagull one for unusual sizes or use with XP. If your printout goes across the page instead of down then again use the Seagull ones. If you upgrade from the Zebra driver to the Seagull driver then check the printer properties afterwards. If this does not have a banner that says 'Drivers by Seagull' then it has pulled the original Zebra driver back in (and Windows is being over-helpful), resulting in you wasting your time.
If you get blank sheets of paper out of the printer when you try to print, even though the Windows test page printed, then the chances are that you are using the wrong paper size in the printer settings. The default paper size is 2 inches by 4 inches. TPN use a paper size of 101.6mm by 203.2mm (4 inches by 8 inches). Set the paper size in Stock and click on the Advanced button and set the values in this section to the same values.
Most problems that we get calls about occur immediately after the change of a label roll and are due to not performing an 'autosense' procedure (as per the manual. You did read it?) Typical effects are spurious characters on the labels or printing the wrong page length. You may even push some printers into Line Mode instead of Page Mode.
Before you start doing a lot of work try changing the printer cable. It may be faulty!
If connecting the printer via USB you should carefully read the instructions in the manual BEFORE attaching the printer. Failure to do so will result in the need for complicated solutions and you will need to contact your supplier to resolve this.
Zebra GK420D - We recommend that you do not use the driver supplied with the printer but use the ZPL driver obtainable from
www.seagullscientific.com - set the paper to portrait and set the orientation to 180 degrees.
