Direct Label Printing With ZPL

October 01, 2024October 01, 2024

As part of the new printer management functionality, we have set up an area under Settings > Printing called Direct ZPL Printing that will allow you to work directly with ZPL-language printers.

 

 

Manage Printers Setting

The purpose of this area is to connect from the browser directly to your printer.

Note - This will only work for printers that support ZPL language such as Zebra or GoDex. Dymo printers do NOT support ZPL.

Below are the functions on the Manage Printers tab:

 

Download Print Proxy

  • This is a very small piece of software that will run in the background. It must be on in order for us to communicate directly to the printer.
  • By default it will run automatically any time the computer is powered on, but if you find this isn’t happening, check the documentation for your operating system on how to set it to run automatically.

 

Add Printer

  • Select from a list of available printers or enter the IP Address and Port.
  • A printer must be assigned to a specific Location.
  • You can name your printer if you’d like it to be different than the default name.
  • ZPL uses units of “Dots Per Inch” or DPI, and right now the only supported DPI density is 203 DPI.
  • You can offset the top and left margins by a specified number of dots. This can be a positive or negative number.
  • You can also increase or decrease the darkness of the print (note - this may vary by printer).

 

Manage Printers

  • You can manage any existing printers by clicking on the 3 dots to the right of the printer name.
  • You can edit a printer which will allow you to change anything you configured when you added the printer.
  • You can “Set as Default” which will auto-select the printer whenever you are printing from the same location as the printer. Only one printer per location can be set as the default. You can also “Remove Default” for any printer that is currently set as the default.
  • You can delete a printer, but please be careful as this will remove the printer for all users and will have to be re-configured if you want to use it in the future.

 

How to Bypass the Browser and Print Directly to the Printer using ZPL

  • If you have at least one printer configured for your location, then when you open the barcode printing modal, you will see the status if your print proxy (online or offline) and you will be able to select a printer and view the connection status (ready to print or offline).
  • In order to bypass the browser and print directly to the printer using ZPL, the print proxy must be Online, and you must select a printer that has a status of “ready to print”.
  • If the print proxy and/or the printer is offline, then the labels will be printed through your browser.
