This is the walkthrough for the Vinty dealer app on Android. If you print from Chrome on your phone instead, see Printing labels — Chrome on Android (the same one-time setup applies).
Your phone must be on the same Wi-Fi network as the label printer.
One-time setup: Mopria Print Service
Android's built-in print service only knows a short list of standard paper sizes (Letter, 4×6, and so on) and hides everything else. Out of the box it offers only 4×6 for the Rollo, even though the printer itself supports 2×1. The fix is the free Mopria Print Service, which lets you add the size yourself. You only do this once.
-
Install Mopria Print Service from the Play Store: play.google.com/store/apps/details?id=org.mopria.printplugin
-
Open the Mopria app. Your Rollo appears under Wi-Fi. (If it doesn't, wait a few seconds, or tap + and enter the printer's IP address — hold the Wi-Fi button on the Rollo to print it out.)
-
Tap the ⓘ next to Rollo X1040.
-
Under Media Ready, tap Custom Media Size. Enter Width 2, Height 1, Units inches, and tap Save.
-
Go to your phone's Settings → Connected devices → Printing (on Samsung: Settings → Connected devices → More connection settings → Printing). Make sure Mopria Print Service is on. If Default Print Service or Samsung Print Service Plugin is also on, turn those off so the Rollo only shows up once.
-
Force-close the Vinty app and open it again.
Printing
- Open the Inventory tab and tick the items you want to tag. Or open an item and tap Print label.
- Tap Print N labels. Set the copies for each item if you need more than one.
- In the Android print dialog, choose Rollo X1040 as the printer.
- Under Paper size, pick Custom (2×1 in), and set Orientation to Landscape. The app asks for this size, but if the dialog comes up as 4×6 / Portrait, set it here.
- Tap the print button.
Your label format comes from Settings (gear) → Default label size in the app, or the store default if you haven't picked one.
Troubleshooting
Paper size only offers 4×6. Mopria isn't the active print service, or the custom size wasn't saved. Re-check steps 4 and 5 above, then force-close and reopen Vinty.
The Rollo isn't listed. It's on a different Wi-Fi network than your phone, or it's asleep — press the Rollo's button to wake it.
Only part of the label prints. The label size in the app's Settings doesn't match the roll in the printer.
