1.Built-in / one machine printing development documents¶
Connection method: Bluetooth (Bluetooth device name: BluetoothPrinter), USB. The third-party APP can print by connecting to the built-in printer. The functions included in the iMin printer: thermal printers with two printing specifications of 58 and 80mm, cutters (some machines), cash drawers (some machines)
The printing function interface of iMin is basically multiplexed, and the model applicable to the document will be slightly different according to the model: D series (D1w, D4), M series (M1, M2, etc.), S series (S1 etc.) Development
The printer is compatible with the ESC & POS command, but it is slightly different from the standard ESC & POS command. Developers can refer to the built-in printer development document to understand the printer’s working mode and interface calling method, and understand the escpos instruction set supported by iMin through the instruction document Built-in printer development documentation
iMin provides printing demo and source code, and supports common printing functions, such as: printing QR code, printing barcode, printing pictures, printing texts in various languages, printing forms, etc. The demo supports both Bluetooth and USB connection methods. Developers need to adapt different SDK files to different iMin devices when developing printing functions.
PS：The demo only supports iMin built-in printers, external Bluetooth serial network USB printers are not suitable for this demo.
iMin printer plugin is an app that provides printing services for iMin POS devices. Users can search for iMinprinterplugin through the iMin App Store. After downloading and installing, you can print PDF content through the printing service function.

2.Print Service F&Q¶
Print paper specifications
Note: The iMin printer supports 58mm and 80mm printing paper. This document uses 58mm printing paper as an example to explain the printer’s support parameters. The specifications of 80mm printing paper are similar
A piece of 58 printing paper has a width of 58mm and an effective printing width of 48mm. The effective printing width is 384 pixels.
The depth of M2 paper chute is 40mm, and it can hold up to 40mm diameter paper.
The depth of D1w / D4 / S1 paper slot is 80mm, and it can hold up to 80mm paper.
What is the printer resolution?
The printer resolution is 205DPI, the calculation formula is as follows
