Zebra Gk420d Label Printer Software

[Amit Bolds]

Didyou know that the Zebra GK420d thermal label printer is one of the most popular desktop thermal label printers ever produced? It is recognised as the top selling desktop label printer in the world!

At Lemon Labels we love the Zebra GK420d it's our favourite label printer for many reasons, not least of all because of it's ease of use, simply drop in a roll of thermal labels, close the lid, hit the feed key and the printer will find the start of the next label and show a green status light, ready to print.

So we know the Zebra GK420d is one of the best label printers available, but the next question we are regularly asked is "what size labels can I use with my Zebra GK420d?" and the answer, is almost any! Well... within a few size constraints:

From the table above you can see the Zebra GK420d is a pretty versatile printer when it comes to label sizes, in short as long as the roll size is not greater than 127mm outer diameter, and not wider than 108mm you can probably fit it in a Zebra GK420d label printer!

Although, with that said, even though the options are huge for label sizes, there are a few popular label sizes that are used in the Zebra GK420d, below we've listed a few of the most popular Zebra GK420d label sizes:

4 x 6" Thermal Labels are probably the most popular labels used in the Zebra GK420d label printer in the UK, they are widely used as courier address labels, as they are a great size to fit on parcels, packages and envelopes but yet still having enough space for the address details, and the couriers tracking details and barcoding for traceability. 4 x 6" Thermal Labels are often also known as 6 x 4" thermal labels, 100 x 150mm thermal labels or 101.6 x 152.4mm thermal labels in metric measurements.

4 x 4" Thermal labels are also very popular for use in the Zebra GK420d and some of the couriers prefer this smaller format for their address labels, sometimes referred to as 101.6 x 101.6mm thermal labels in metric measurements.

2 x 1" Thermal labels are our third most popular label size for use in the Zebra GK420d label printer, these labels are often used for barcode labelling and price labelling for shops, stores, and warehouses to identify products easily using a barcoding system, or to apply SKU labels, commonly referred to as 50 x 25mm thermal labels in metric measurements.

Alongside size, label material is the most important consideration when purchasing labels for use in your Zebra GK420d printer, this model of printer is a direct thermal only printer, meaning that it only works with labels that has a special heat sensitive coating, in contrast to thermal transfer label printers that use a separate ink ribbon to apply the printed image to the label.

Firstly, our most popular material is a thermal eco paper this is widely used for courier labels as it strikes a great balance between quality and print definition against cost for short life labels, thermal eco paper labels are the most popular option for courier labels.

Secondly, we offer a top coated thermal paper, this material is very similar to our thermal eco paper but has a protective top coating over the top making the printed label more robust, less easily marked by knocks and abrasions, and resistant to the presence of small amounts of oils, grease and water, although remember top coated thermal paper labels are still made from paper and as such are still not a waterproof option.

Thirdly, at Lemon Labels we offer our weatherproof direct thermal polypropylene labels for the Zebra GK420d, this material is great, it's made from a tough polypropylene material that is scratch resistant and water resistant, it is ideal for use in environments where the labels may get wet, we see these labels being used successfully in places like garden centres to label plant pots, whether the labels get rained on or just watered as part of plant care they will be absolutely fine and the barcodes will still scan when your customer gets to the checkout!

We have had this problem with the Zebra GK420t printers. Updating the firmware did not help. We found that the printers are very sensitive to broadcast traffic. We solved the problem by putting the printers on a VLAN to separate them from the main network. If your network is small look for a malfunctioning pc or server that is sending out a lot of broadcasts.

We have over a dozen Zebra GK420d label printers that constantly fall off our network for no apparent reason. They have been functioning perfectly until now and nothing has changed on our network that would cause this to happen.

We have introduced a D-Link USB print server today which is preventing the problem happening on the two that are using it - more of these or a VLAN as you suggest may be the way forward to get us through the Christmas period but we would like to get this fixed without having to resort to a workaround.

The only way we managed to solve this was to put a small unmanaged switch such as a Netgear GS105 or a print server such as a DLink DPR-1061 between the printer and main network switch. We tested both successfully but used the print servers for our setup in the end.

Turned out to be a print-server that had a job queue for the IP address I used. I spent two weeks troubleshooting. With a pile of blank labels on the floor caused by the print server attempting to finish the queued jobs.
