Quick Answer: To swap labels on your JPS 2000, physically move the label rolls between printers, set both printers to 1x1 in the printers settings, then update each printer to its correct label size and run calibration.
Follow the steps below for full details.
Physically swap your label sizes from one printer to the other (e.g., move 2x8 labels into 1x1 printer or vice versa).
Log in to the Jolt web app and navigate to settings > printers.
Click on the kebab menu (three vertical dots) and select printer settings.
Select one of your printers (e.g., 50N221345387).
Click on the label size tab and change label size to 1x1.
Click save. You will be asked to run a calibration. Click not now.
Repeat from step 2 for the other printer.
At this point both printers should be set to 1x1 and labels should be swapped.
Find the serial number on the physical printer (behind the label roll).
Go to Jolt web app settings > printers.
Select the printer that matches the serial number of the physical printer.
Click on the labels tab.
Change the label size to match the labels physically loaded into the printer (e.g., if your printer has 2x8 labels loaded, select 2.2x8).
Repeat from step 9 for the other printer.
Both printers should have their new label size and correct labels loaded.
Run calibration to ensure your printer is configured for the new label size. You can do this from the Jolt web app (under printer settings) by tapping run calibration.
