# @kduma-autoid/capacitor-sunmi-printer

Adapter for printing on internal printers of Sunmi POS devices

## Install

```bash
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`. 

```typescript
/// <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:

1. You can build the prints procedurally using method calls. It's ideal for smaller printouts and in new projects.
2. 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
```typescript
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.cutPaper(); // or SunmiPrinter.lineWrap({lines: 3});

SunmiPrinter.exitPrinterBuffer();
```

### Example 2 - Printing already prepared ESC/POS commands
```typescript
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();
```

**Returns:** <code>Promise&lt;{ name: string; }&gt;</code>

--------------------


### updatePrinterState()

```typescript
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:** <code>Promise&lt;{ status: <a href="#printerstatusenum">PrinterStatusEnum</a>; code: number; }&gt;</code>

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:** <code>Promise&lt;{ length: number; }&gt;</code>

--------------------


### getPrinterPaper()

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

### setFontName(...)

```typescript
setFontName(options: { typeface: string; }) => Promise<void>
```

Set custom print font.

typeface → specify the custom font name you’re about to use. Currently only vector font supported, and the font needs to be preset in the app assets directory.

Note 1: this interface can expand the default font type in the printer for you to use a custom font. However, you have to adjust the line spacing and line width due to the inconsistent inner width of each font.

Note 2: this interface is available for the printing service with versions above v4.14.0.

| Param         | Type                               |

Note: global method may influence the subsequent printing, and you can cancel this setting using printer initialization. The font size adopts the printing method exceeding the standard international commands, and the adjustment of font size may affect the character width, which leads to the change to the number of each line’s characters. So typography of monospaced fonts can be confusing some time.

| Param         | Type                           |

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.

Note: if you need to change the style of print text, such as alignment mode, font size, bold, etc., please set it before calling printText method.

| Param         | Type                           |
| ------------- | ------------------------------ |
| **`options`** | <code>{ text: string; }</code> |

--------------------


### printTextWithFont(...)

```typescript
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`** | <code>{ text: string; typeface: string; size: number; }</code> |

--------------------


### printOriginalText(...)

```typescript
printOriginalText(options: { text: string; }) => Promise<void>
```

Print vector font.

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.

Note: the text is printed according to the vector text width, which means that each character is not monospaced.

| Param         | Type                           |
| ------------- | ------------------------------ |
| **`options`** | <code>{ text: string; }</code> |

--------------------


### printColumnsText(...)

```typescript
printColumnsText(options: { lines: { text: string; width: number; align: AlignmentModeEnum; }[]; }) => Promise<void>
```

Print a column of a table (Arabic characters are not supported)

colsTextArr → Array of column text strings.
colsWidthArr → Array of each column width, calculated in English characters, and each Chinese character is equal to two English characters, with each width &gt; 0.
colsAlign → Alignment mode of each column: 0: left; 1: center; 2: right.

Note: the array length of the above three parameters should be consistent. If the width of colsText[i] is larger than that of colsWidth[i], the text will be changed to another line, and Arabic characters are not supported.

| Param         | Type                                                                                                                   |
| ------------- | ---------------------------------------------------------------------------------------------------------------------- |
| **`options`** | <code>{ lines: { text: string; width: number; align: <a href="#alignmentmodeenum">AlignmentModeEnum</a>; }[]; }</code> |

### labelLocate()

```typescript
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

--------------------
