Why This Happens
Who this is for. This is for stores that print labels through Zebra Browser Print, the free Zebra app on the computer your label printer is plugged into. If your store uses network label printing on a Mac or an Elo register, see Setting Up Network Label Printing instead.
Back Office can only see your printer through Browser Print. If the app isn't open, your printer won't show up, even if it's plugged in and switched on.
Chrome also needs permission to talk to the app. Chrome blocks websites from reaching apps on your computer unless you allow it. If that permission is off, Back Office can't find Browser Print.
Check 1: Make Sure Browser Print Is Open
Step 1
Open Zebra Browser Print on the computer your label printer is plugged into.
On a Mac: Open your "Applications" folder, find "Zebra Browser Print," and double-click it. It may look like nothing happens, but it's running. You'll see a small Zebra icon in the menu bar at the top of the screen.
On Windows: Open the Start menu, search for "Zebra Browser Print," and click it. You'll see a small Zebra logo in the system tray, at the bottom right of the screen.
If double-clicking doesn't seem to work, right-click the app and choose "Open."
Step 2
Go back to the "Shelf label print queue" page in Chrome and refresh it.
Step 3
Select your labels and click "Print" again. Check whether your printer now shows up under "Select Printer." If it does, you're done. If it still says "No printers available," go on to Check 2.
Check 2: Let Chrome Reach Apps on Your Computer
Step 4
In Chrome, click the small icon at the left end of the address bar, just before "app.scotchpos.com."
Step 5
Turn on "Apps on device."
Step 6
Chrome shows a message asking you to reload the page. Click "Reload," or refresh the page yourself.
Step 7
Select your labels and click "Print." Your printer should now show up under "Select Printer."
Note: If you ever click "Block" when Chrome asks to let the site reach devices on your computer, Chrome remembers it. Turning on "Apps on device" in Step 5 undoes that.
Troubleshooting
Still "No printers available" after both checks: Make sure the printer is switched on and its USB cable is plugged into this computer. Then close Browser Print, open it again, and refresh the page.
Browser Print opens, but there's no Zebra icon: Close it completely and open it again. On a Mac, check the menu bar at the top. On Windows, click the small arrow in the system tray to see hidden icons.
You don't have Zebra Browser Print: Download it from Zebra's website and install it on the computer your printer is plugged into. See Setting Up Your Zebra ZD411 Label Printer.
"Apps on device" isn't in the menu: Update Chrome to the latest version, then try again.
You're using a different browser: Label printing only works in Google Chrome. Open Back Office in Chrome and try again.
The printer showed up before but disappeared: Browser Print may have closed, for example after the computer restarted. Open it again (see Check 1).
