If labels aren't printing, or they're printing out of position, work through the checks below in order. Most printing problems come down to the Hub, the printer's network connection, or the printer's label calibration.

Check Your DataNinja Hub

A red power indicator light (a green light on Hubs sold or provided after 2023) should be visible on the side of the Hub opposite the USB ports. If you don't see the light, check the power connections. Next, make sure the Ethernet cable is connected and that the Ethernet connection to the internet is working.

Check Your Printer's Connection

From any screen, click the gear icon, then select "Printers" from the Tools column. Open the printer that's having trouble and click the small box next to its IP address.

You should then see a screen that looks like this:

If the printer status is Ready, your printer is connected to your network and DataNinja has the correct information. If you see a red error message instead, the printer usually isn't closed properly or is out of labels or ribbon.

If a page like the one above never loads when you click the box next to the IP address, either your printer isn't connected to the network, or its IP address is different from the one saved in DataNinja.

Printer IP Address in DataNinja is Incorrect

If the printer has a different IP address, go back to the Printers page (from any screen, click the gear icon, then select "Printers" from the Tools column). In the top right of the page, click "Discover Printers". Wait 60 seconds for the Hub to find all printers, then try printing again.

Re-Calibrate the Printer

If the printer is printing labels out of position, or printing on every other label, hold down the "X" and "Pause" buttons for two seconds to recalibrate the label feed.

Still Not Working?

If your Hub is powered on and online, and the printer connection check above shows Ready, you shouldn't have any trouble printing. Use the blue chat bubble on this page to reach our Support team, and a team member will help.
