directprint #
Directprint The plugin allows Flutter applications to raw print to Windows printers using the OpenPrinter/StartDocPrinter system functions, mainly for sending raw text and control codes to POS printers.
The plugin is intended for the Windows platform.
Getting Started #
The Directprint() class allows you to send codes directly to a Windows printer with the help of the "print" method.
Future<String?> print(String printer, String job, Uint8List data)
Call the "print" method with arguments:
String printer - Sistem printer name
String job - Specifying job name in print queue
Uint8List data - raw data bytes
The result of the call is a Future String with the following content:
"OK" - if the call ended without error
"ERROR:1" - Error: Opening Printer
"ERROR:2" - Error: Opening Document
"ERROR:3" - Error: Starting Page
"ERROR:4" - Error: Printing Count```
