The Zebra GK240d direct thermal label printer is probably the UK’s best selling label printer. The incredibly simple clamshell design allows the quick change of labels: plus a slot at the rear of the printer allows the use of fanfold tags or labels. There is no printer ribbon: no ink or any other consumable other than the labels.

This model has USB and serial connectivity and is supplied with the basic Zebra Designer labelling software and Windows drivers so printing from most Windows applications is very easy. As this model is extensively used for printing shipping and courier labels: it has become the label printer of choice for printing Royal Mail DMO labels. In fact this model is recommended by Royal Mail. The GK420d can take a range of labels including the standard 150mm x 100mm courier labels and labels supplied by Royal Mail and Parcelforce.

Despite its low cost the Zebra GK2420d label printer is surprisingly robust: our own warehouse uses several and they have performed day in day out with nothing more than an occasional clean of the printhead. The label print speed is excellent and the clarity of print on barcodes is excellent ensuring that the tracking of stock and parcels is never a problem.

Hi I have question related to Zebra GK420D 203dpi Label Printer could i use Z-Select 2000D DT Label/ 32mmx25mm rolls on him?

If the labels are on the 25mm cores then they will be fine in the GK420D
Best Regards

Hi Does this printer print label size 4 x 6 Inch?

Hi. Yes this printer will take a 4 wide labe so a 4 x 6 will be fine.
Best Regards


Does this printer work Mac OS 10.6 and can it be networked. Thanks

Zebra do not supply the drivers for their products to work with Mac they only provide windows drivers. This particular printer does not have a network card onboard however you can buy a networked version of the GK420D.

Hi, does this particular model have ZPL emulation?

The GK420D has both ZPL and EPL emulation. This can be found within the brochure which can be downloaded from the download tab on the product page.

What is the biggest size labels i can order for the above printer? Regards James

The maximum print width for this printer is 104mm the maximum length this printer will print is 990mm (using continuous media) attached is a list of Direct Thermal Labels that will fit this printer.

Is this printer compatible for wireless network so more than one computer can print to this printer?

This printer does not have wireless capabilities you would need to look at the GX range of Zebra printers which have a wireless option available.

I need to print directly to the printer from a PC application I am writing. I can directly control the RS232 port so does the printer support direct access using say Epson print codes?

Hi, there is a programming manual available here.
This should give you what you need. If not let us know and we can put in touch with Zebra tech support.
