For example, when we see this pdf document, we can see that the document describes an instruction, then we can write like this:

js
import printease from 'printease'
let cude = new printease.customDirective.CustomDirectiveLib()
// cude.setEncoding('GB18030')
cude.setCommand('^XA')
cude.setNewLine()
cude.setCommand('^FO50,50')
cude.setNewLine()
cude.setCommand('^A0,32,25')
cude.setNewLine()
cude.setCommand('^FDZEBRA^FS')
cude.setNewLine()
cude.setCommand('^FO50,150')
cude.setNewLine()
cude.setCommand('^A0,32,25')
cude.setNewLine()
cude.setCommand('^FDPROGRAMMING^FS')
cude.setNewLine()
cude.setCommand('^FO50,250')
cude.setNewLine()
cude.setCommand('^A0,32,25^FDLANGUAGE^FS')
cude.setNewLine()
cude.setCommand('^XZ')
cude.setNewLine()
console.log(cude.getBuffer())

That's it, you can do whatever you want with reference to this pdf Isn’t it convenient to customize instructions? After the buffer data is obtained, it can be transferred to the printer.

cude.setCommand('SIZE 60 mm, 40 mm')
cude.setNewLine()
cude.setCommand('GAP 0 mm, 0 mm')
cude.setNewLine()

You can pass this buffer data to the printer.

If you have custom bitmap data, please pass in an array, otherwise your bitmap data will be encoded, resulting in incorrect

For example, your bitmap data format BITMAP 10,20,10,15,30

js
import printease from 'printease'
let cude = new printease.customDirective.CustomDirectiveLib()
// cude.setEncoding('GB18030')
cude.setCommand('BITMAP')
cude.setCommand([10,20,10,15,30])
cude.setNewLine()
// ....... other commands
console.log(cude.getBuffer())
