# Printing
Inventory, location, and other screens now include an option to print barcodes as shown below.
In addition, a QR code and full label is rendered in the print modal as a preview.
### Printer requirements
Not all printers will work with ION's v1 implementation. We require printers to do be able to do 2 things:
1. Connect to the internet(wifi or ethernet)
2. Work with middleware named [**Zebra Browser Print**](https://www.zebra.com/us/en/support-downloads/software/printer-software/browser-print.html)**. This has to be downloaded** on each users computer to enable printing. ION communicates with this desktop application, which then in turn communicates with the printers.
#### Printers that work with ION
The Zebra brand Printers generally work with Zebra Browser Print and therefore ION. You should order one of those printers to print barcodes with ION.
## Troubleshooting
If you get an error message that looks like this:
If means you have the "Use Print Server" button checked, but you don't have an API key set in your organizational settings. Please check that you meant to enable the print server feature, and either fill in the API key or uncheck the box.
