For Star Micronics bluetooth/LAN printers. It works only with Android.

How to use :

API

Printer discovery

// Create a new builder

  .then(list => {
    // all discovery devices
  })
  .catch(error => {
    // error
  })

  .then(status => {
      // status result
  })

Print receipt

Builder

You need use the Builder to create the commands pipeline.

To print a receipt you need create a builder with this code:

  const builder = new Builder({ width: 384 });

The width represent the paper width. With the instance of builder is possible now add commands.

  builder.text("Hello world", {});

In example a text command was added in pipeline. the second argument is a object that represent a style of text. Below follow all the possible values.

• size : int | size of text.
• font : string | font family: monospace, sans serife, serife or default.
• weight : string | weight of text: bold, bold italic, italic or normal.
• align : string | align of text: center, opposite or normal.

Example with default configuration of style.

  builder.text("Hello world", {
    size: 15,
    font: 'default',
    weight: 'normal',
    align: 'normal',
  });

Full example with 3 lines:

  const builder = new Builder({ width: 384 })
     .text("Hello world", {})
     .text("This is a example", {})
     .text("Say, good bye!", {})
     .cutPaper();

  builder.print(portName)
    .then(sucess => {
        // sucess
    })
    .catch(error => {
        // error
    })

Example with shared style:

  var myStyle = {
    size: 23,
    weight: 'bold',
    align: 'center'
  };

  const builder = new Builder({ width: 384 })
     .text("Title in center", myStyle)
     .text("I'm center too", myStyle)
     .text("all is center", myStyle)
     .cutPaper();
    
  builder.print(portName)
    .then(sucess => {
        // sucess
    })
    .catch(error => {
        // error
    })

Other functions

Image

Add a image to builder. The first input must be a base64 encoded image.

  builder.image('data:image/jpg;base64, ....');

The second param is optional, but you can change the width anda the align when pass a style.

  builder.image('data:image/jpg;base64, ....', {
    align: 'center'
  });

Style image options:

• width : int | size of image.
• align : string | align of image: center, left or right.

Cutpaper

Cut the paper.

  builder.cutPaper();

Open Cash Drawer

I'm not sure if this work with TSP100.

  builder.openCashDrawer();

print

Finally for print, just call print command. This function will return a promise.

builder.print(portName);
