Need to support APIs to access POS peripheral devices through background tasks
Use case to be achieved-
In an app that collects status information of assets, the user should be able to scan barcode of an asset (background task), and enter other information in the app (foreground task) while the barcode data is being retrieved (background task) and sent to the app (data transfer from background task to foreground task)11 votes
You should update all the constants for the paper sizes for example constant for CR80 or business card and POS receipt paper wasn't stated but you wrote other sizes are being reserved .
Am even stock now , I would be glad if you can update it now.
