Shipping labels 102 - paper size, label format and printer choices

Fulfillment Wednesday today will tell you how to setup your printer, and what label size and format you should choose when printing electronic shipping labels (i.e. online labels) with thermal printers and desktop printers.

Label paper sizes & Printer Type

In general there are* 2 different paper sizes* for shipping labels:

Paper SizePrinter TypeCourier
4" x 6" Thermal printerUPS, DHL, FedEx, USPS, Royal Mail
8" x 11.5" (~A4)Laser or inkjet printerAll couriers

Basically 4x6 paper size is used when printing labels with thermal printers. Unlike normal desktop printers using normal A4 papers, thermal printers are using heat-sensitive sticker paper which is faster in printing and allows you to stick the label on the package directly. And do note that some couriers (e.g. tnt, Hong Kong post) do NOT support 4x6 label size, i.e. you have to print it on a 8x11.5 A4 paper. And of course, an A4 paper can cover a label with size of 4" x 6".

Label Format

In terms of choose the label format, I recommend PDF for a few reasons. Reasons:

  1. Most couriers only provide PDF format. Period.
  2. PDF requires minimal settings before printing
  3. PDF can be printed via all printer types

Of course if you want to include a label into your invoice / packing slip, then PNG could be the idea. I will suggest you to say goodbye to EPL, ZPL and ZPLII as I dont see any new couriers are returning these format to users.

Printer choices - Laser, inkjet or thermal printer

If you're just shipping a low volume, simply use a laser or injet printer. For injet printer, just watch out the label quality and try to scan the barcode (using some mobile apps) before shipping. When you have certain high volume and make sure the courier you are using support 4x6 label size, then you should seriously consider a thermal printer.
