Three ways to connect
The printer must understand ESC/POS and provide at least one of these connections.
Network
Connect using an IP address and TCP port. Receipt printers commonly use port 9100, but check your model.
USB
Direct connection using a cable or OTG adapter. Android asks for permission to access the USB device.
Bluetooth
Pair the printer in Android settings first, then select it in PosPrinterDriver.
Four ways to send jobs
Another Android app
Use ACTION_SEND or share content and, where supported, specify printer 1 to 5.
Open guideA website
Open an explicit link that Android passes to the installed app.
Open guideA server
Register the device with its linkcode and place the job in the remote queue.
Open guideShare menu
Send text, an image or a PDF from compatible Android apps.
