Current status of printer

Returns: Promise<{ printstats: string; }>

Sunmi_GetIsConnnected()

Sunmi_GetIsConnnected() => Promise<{ isConnnected: string; }>

Check if the printer is connected

Returns: Promise<{ isConnnected: string; }>

Sunmi_PrintBitmap(...)

Sunmi_PrintBitmap(options: QR_Image_Print) => Promise<{ value: string; }>

Print pictures and text in the specified orde After the picture is printed, the line feed output needs to be called, otherwise it will be saved in the cache In this example, the image will be printed because the print text content is added

Returns: Promise<{ value: string; }>

Sunmi_PrintText(...)

Sunmi_PrintText(options: Sunmi_PrintText) => Promise<{ value: string; }>

print text Set printer alignment ==> Sunmi_SetAlign 0 : Left, 1 : Center, 2 : Right

Returns: Promise<{ value: string; }>

Sunmi_PrintTextFont(...)

Sunmi_PrintTextFont(options: Sunmi_PrintText_Font) => Promise<{ value: string; }>

print text You can put the custom font in the 'assets' directory and Specify the font name parameters Set printer alignment ==> Sunmi_SetAlign 0 : Left, 1 : Center, 2 : Right

Returns: Promise<{ value: string; }>

Sunmi_PrintLine(...)

Sunmi_PrintLine(options: Sunmi_Print_Line) => Promise<{ value: string; }>

paper feed three lines Not disabled when line spacing is set to 0 max line 3

Returns: Promise<{ value: string; }>

Sunmi_SetAlign(...)

Sunmi_SetAlign(options: Sunmi_Text_Align) => Promise<{ value: string; }>

Set printer alignment 0 : Left, 1 : Center, 2 : Right

Returns: Promise<{ value: string; }>

Sunmi_FeedPaper()

Sunmi_FeedPaper() => Promise<{ value: string; }>

Due to the distance between the paper hatch and the print head, the paper needs to be fed out automatically But if the Api does not support it, it will be replaced by printing three lines

Returns: Promise<{ value: string; }>
