@kduma-autoid/capacitor-sunmi-printer

Adapter for printing on internal printers of Sunmi POS devices

Install

npm install @kduma-autoid/capacitor-sunmi-printer
npx cap sync

Configuration

You can disable auto binding of the service by setting bindOnLoad to false in the plugin configuration in capacitor.config.ts.

/// <reference types="@kduma-autoid/capacitor-sunmi-printer" />
import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: "com.company.app",
  ...
  plugins: {
    SunmiPrinter: {
      bindOnLoad: true
    }
  }
}
export default config;

Example Usage

You can interact with the printer in two ways:

You can build the prints procedurally using method calls. It's ideal for smaller printouts and in new projects.
Or you can print by sending commands from a subset of ESC/POS print language - it's ideal for larger documents, legacy applications or when receiving whole printouts from a remote server.

Example 1 - Printing using built-in methods

SunmiPrinter.enterPrinterBuffer();

SunmiPrinter.setFontSize({ size: 35 });
SunmiPrinter.setBold({ enable: true });
SunmiPrinter.setAlignment({ alignment: AlignmentModeEnum.LEFT });
SunmiPrinter.printText({ text: "This is an\n" });

SunmiPrinter.setFontSize({ size: 65 });
SunmiPrinter.setBold({ enable: false });
SunmiPrinter.setAlignment({ alignment: AlignmentModeEnum.CENTER });
SunmiPrinter.setAntiWhitePrintStyle({ enable: true });
SunmiPrinter.printText({ text: "EXAMPLE\n" });

SunmiPrinter.setFontSize({ size: 30 });
SunmiPrinter.setAlignment({ alignment: AlignmentModeEnum.RIGHT });
SunmiPrinter.setAntiWhitePrintStyle({ enable: false });
SunmiPrinter.printText({ text: "of a SunmiPrinter plugin\n" });

SunmiPrinter.setAlignment({ alignment: AlignmentModeEnum.CENTER });
SunmiPrinter.printBarCode({ content: "1234567890", symbology: BarcodeSymbologyEnum.CODE_128, height: 100, width: 2, text_position: BarcodeTextPositionEnum.BELOW });

SunmiPrinter.lineWrap({lines: 3});

SunmiPrinter.exitPrinterBuffer();

Example 2 - Printing already prepared ESC/POS commands

SunmiPrinter.enterPrinterBuffer();

const escpos = "\u001b@\u001ba\u0001\u001d!\u0011Hello\n\u001bE\u0001\u001d!\u0010SunmiPrinter\n\u001bE\u0000\u001d!\u0013EXAMPLE\n\u001d!\u0000\u001bE\u0001plugin\n\n\n\n\u001bE\u0000";
SunmiPrinter.sendRAWData({data: escpos});

SunmiPrinter.exitPrinterBuffer();

API

bindService()

bindService() => Promise<void>

bind print service

unBindService()

unBindService() => Promise<void>

unbind print service

getServiceStatus()

getServiceStatus() => Promise<{ status: ServiceStatusEnum; }>

Get the print service current status

Returns: Promise<{ status: ServiceStatusEnum; }>

printerInit()

printerInit() => Promise<void>

Printer initialization

Note: reset the printer's logical program, such as typography, bold, etc., without emptying the cached data, then the unfinished print tasks will continue after resetting.

printerSelfChecking()

printerSelfChecking() => Promise<void>

Printer self-checking

getPrinterSerialNo()

getPrinterSerialNo() => Promise<{ serial_number: string; }>

Get the printer’s serial no.

Returns: Promise<{ serial_number: string; }>

getPrinterModel()

getPrinterModel() => Promise<{ model: string; }>

Get the interface of printer model

Returns: Promise<{ model: string; }>

getPrinterVersion()

getPrinterVersion() => Promise<{ version: string; }>

Get the printer’s firmware version no.

Returns: Promise<{ version: string; }>

getDeviceName()

getDeviceName() => Promise<{ name: string; }>

Device name

Returns: Promise<{ name: string; }>

updatePrinterState()

updatePrinterState() => Promise<{ status: PrinterStatusEnum; code: number; }>

Get the printer’s latest status

1 → Printer is under normal operation 2 → Printer is under preparation 3 → Communication is abnormal 4 → Out of paper 5 → Overheated 6 → Cover is open 7 → Cutter error 8 → Cutter recovered 9 → Black mark not detected 505 → Printer not detected 507 → Printer firmware update failed

Note 1: these return values are applicable to all SUNMI devices, but some status can’t be obtained due to hardware configuration. For example, cover open detection is not applicable to handheld devices.

Note 2: V1 devices currently can’t support this interface; you can also get it asynchronously by registering broadcast apart from getting status proactively

Returns: Promise<{ status: PrinterStatusEnum; code: number; }>

getServiceVersion()

getServiceVersion() => Promise<{ version: string; }>

Get the printing service version no.

Returns: Promise<{ version: string; }>

getPrintedLength()

getPrintedLength() => Promise<{ length: number; }>

Get the print length of the printhead

Note: currently you can get the printed length since powering on the device.

Due to the hardware differences between desktop devices and handheld devices, the returns of printing results may vary. In other words, you can get the printed length through ICallback callback interface for handheld devices, and get the printed length directly through the return values for desktop devices.

Returns: Promise<{ length: number; }>

getPrinterPaper()

getPrinterPaper() => Promise<{ paper: number; }>

Get the printer’s current paper specification

Note 1: by default, 58mm paper specification is adopted for handheld printers, and 80mm paper specification for desktop printers but you can add a fixator and set the printer to use a 58mm paper roll by configuration, and the interface will return the current paper specification set for the printer.

Note 2: currently, desktop device T1 model with versions above v2.4.0 supports this interface; T2 and S2 models with versions above v1.0.5 support this interface; for other device models with versions above v4.1.2, they all support this interface for getting paper specification.

printTextWithFont(...)

printTextWithFont(options: { text: string; typeface: string; size: number; }) => Promise<void>

Print text with designated font and size.

text → text to be printed; automatic linefeed will be implemented when the text width exceeds one line, and the forced newline character "\n" shall be added at the end of one line when the text width is less than one line or exceeds one line but not meeting one line before being printed, or it will be cached. Typeface → the custom font name. Currently only vector fonts are supported, and the font needs to be preset in the app assets directory. fontSize → font size; only available for this method.

Note: the font setting of this interface is available for the printing service with versions above v4.14.0.

| Param | Type | | ------------- | -------------------------------------------------------------- | | options | { text: string; typeface: string; size: number; } |

labelLocate()

labelLocate() => Promise<void>

Locate the next label

You can only implement the location output operation specific to the label by calling the label interfaces, while the label content needs to be customized by yourself according to your own needs, like the operation of thermal printing.

Please note that the height of printing content shall be within the label paper, or the printing content may exceed the label paper, which can result in printing to the next label or inaccurate location of the next label.

If you use a label paper with 30mm height, you can print the content with 240 pixels (30mm x 8 pixels), and the printer defaults to 32 pixels of line spacing, which allows you to print about 8 lines of text or a 384x240 image.

After printing the content, you can choose to implement labelLocate and print the content circularly according to your own needs.

If you don’t need to print any more, you can implement labelOutput(), which can output the label to the paper cutting position, facilitating you to add other APIs according to needs to design your own label content.

Note: You need to locate the label position every time before sending the printing content

labelOutput()

labelOutput() => Promise<void>

Output the label to the paper cutting position
