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

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, default is 4.font
:string
| font:FONT_A
,FONT_B
,FONT_C
,FONT_D
,FONT_E
.weight
:string
| weight of text:bold
ornormal
.align

.
Example with default configuration of style.
builder.text("Hello world", {
size: 4,

});
Full example with 3 lines:
window.plugins.starPrinter.Builder({ width: 384 })
