Detailed Description

This class manages newlines and character encoding for the target printer, and can be interchanged for an image-bassed buffer (ImagePrintBuffer) if you can't get it operating properly on your machine.

(

)

Used by Escpos to check if a printer is set.

Implements Mike42\Escpos\PrintBuffers\PrintBuffer.

Mike42\Escpos\PrintBuffers\EscposPrintBuffer::setPrinter

(

Printer

$printer = null

Used by Escpos to hook up one-to-one link between buffers and printers.

Parameters

Printer | null

$printer

New printer

Implements Mike42\Escpos\PrintBuffers\PrintBuffer.
