Print to the built-in printer of a Sunmi device with BizPrint

This page shows you how to print BizPrint orders on the printer that is built into a Sunmi device, such as a Sunmi POS terminal or handheld. It is for merchants who use a Sunmi device as their BizPrint station with the BizPrint Android app.

The app prints to the built-in printer directly. You do not pair it, plug it in or enter an address, and the app reads the paper width for you.

Before you start

Section titled “Before you start”

Add the built-in printer

Section titled “Add the built-in printer”
  1. Open the BizPrint app on the Sunmi device.
  2. Tap Add printer under Printers on the main screen. If you are in the setup assistant, tap Add printer on the Add a printer step instead. The Add printer screen opens and starts looking for printers.
  3. Tap Built-in printer. Its second line says This device.
  4. Type a name in Printer name, for example “Counter”. BizPrint shows this name in the BizPrint dashboard and in your printer location, so choose one your staff will recognize.
  5. Tap Continue. The app shows Checking the printer, then Printing a test page.
  6. Look at the printer for the test page. The test page is not an order.
  7. Tap Yes under Did it print? if the test page printed. The printer page opens.

If you tap No, the app shows The test page didn’t print. Tap Try again to print it again. If it still does not print, see Fix built-in printer errors.

A device has one built-in printer, so you add it once. After that, it is listed under Already on this phone on the Add printer screen.

For more about the Add printer screen, see Add a printer to the BizPrint Android app.

Check the paper width and cut

Section titled “Check the paper width and cut”

The app reads the paper width from the device when you add the printer:

  • On 80 mm paper, Paper is set to 80 mm roll and Cut after job to Partial cut.
  • On 58 mm paper, or when the device does not report a width, Paper is set to 58 mm roll and Cut after job to No cut.

To check or change these:

  1. Tap the printer under Printers on the main screen of the app. The printer page opens.
  2. Tap Paper under Paper and output.
  3. Choose 58 mm roll or 80 mm roll to match your paper.
  4. Tap Advanced.
  5. Tap Cut after job.
  6. Choose Partial cut, Full cut or No cut. Choose No cut if your device has no paper cutter.
  7. Tap the back arrow to return to the printer page.
  8. Tap Test print to check the change.

For the other settings, such as margins and fonts, see Change paper, cut and layout settings for a printer in the BizPrint Android app.

Set up the printer location in WooCommerce

Section titled “Set up the printer location in WooCommerce”

If you use the BizPrint plugin for WooCommerce, choose the built-in printer in a printer location. See Set up a WooCommerce printer location for an Android station with BizPrint. These tips help on a Sunmi device:

  • The printer is listed in the location’s Printers box with your station name and the name you typed in the app.
  • Receipt templates such as Customer Receipt and Order Receipt fit receipt paper well.
  • Either output format works. Choose HTML to print your logo and the template’s layout. Choose Plain Text for fast text printouts in the printer’s own fonts.
  • With Plain Text, type the number of characters that fit on one line of your paper in Plain text format symbols width. The test page from Test print has a line of numbers and a tip that helps you count them.
  • The app prints on the paper set in Paper in the app. The location’s Layout Size and margins are used only when Page size from job in the printer’s Advanced page is set to Use the job page size when sent.

Check before you send a test order

Section titled “Check before you send a test order”

A Test print from a WooCommerce printer location prints a real order again. Before you send one, do these checks so you do not print an order twice:

  1. Look at the paper at the Sunmi device for the order’s printout.
  2. Check that the printer has paper and is not in the middle of a real order.
  3. Check the print job status of the latest print jobs in the BizPrint dashboard. See View print jobs and their status in the BizPrint dashboard.
  4. Wait for the station to finish anything it is still printing, whatever status the job shows.

Then follow Send a test print from a BizPrint printer location in WooCommerce.

The Test print button on the printer page in the app, and Print test page in the setup assistant, print the app’s own test page, not an order. You can use them at any time.

Fix built-in printer errors

Section titled “Fix built-in printer errors”

Symptom: A job or test shows This device has no built-in printer.

Cause: The app cannot find the printer service of a Sunmi built-in printer on this device. This also means Built-in printer is not listed on the Add printer screen.

Fix: Check that you are using a Sunmi device with a built-in printer. On a device without a built-in printer, add a network, Bluetooth or USB printer instead. See Add a printer to the BizPrint Android app.

Symptom: A job or test shows This device’s printer service did not respond.

Cause: The device’s printer service did not answer the app.

Fix: Restart the Sunmi device, open the BizPrint app, and tap Test print on the printer page.

Symptom: A job or test shows The built-in printer stopped responding.

Cause: The printer stopped while it was printing, for example because the paper ran out or the cover was opened.

Fix: Check that the printer has paper and the cover is closed. Then tap Test print on the printer page. If it still fails, restart the device. Before you print a real order again, do the checks in Check before you send a test order.
