Receipt on POS Printers Not Taking Full Width #1571

Open MuhammadUmair786 opened 8 months ago

MuhammadUmair786 commented 8 months ago

Describe the bug

  1. I have set up a custom page format using const PdfPageFormat(...), but the content does not extend to the full width.
  2. When "Fit to printable area" is selected, the content aligns center, and there is empty space at the top.

To Reproduce Code snippet to reproduce the behavior:

import 'package:pdf/pdf.dart';
import 'package:pdf/widgets.dart' as pw;
import 'package:printing/printing.dart';
import 'package:get/get.dart';

class PrintTest {
  final PdfPageFormat pageFormat;
  final double fontSize;

  PrintTest({required this.pageFormat, required this.fontSize});
}

const double defaultFontSize = 5;

Future<void> printImgTest3() async {
  List<String> toStringList = [
    "PdfPageFormat.a3",
    "PdfPageFormat.a4",
    "PdfPageFormat.a5",
    "PdfPageFormat.a6",
    "PdfPageFormat.legal",
    "PdfPageFormat.letter",
    "PdfPageFormat.roll57",
    "PdfPageFormat.roll80",
    "PdfPageFormat.undefined",
    "28 x 2",
  ];
  Get.generalDialog<PrintTest>(
    pageBuilder: (_, __, ___) {
      TextEditingController widthController = TextEditingController();
      TextEditingController heightController = TextEditingController();

      TextEditingController marginController = TextEditingController(text: '2');
      TextEditingController fontSizeController =
          TextEditingController(text: '$defaultFontSize');
      final GlobalKey<FormState> formKey = GlobalKey<FormState>();

      return Align(
        alignment: Alignment.center,
        child: Container(
          width: 400,
          margin: const EdgeInsets.all(20),
          padding: const EdgeInsets.all(20),
          child: Material(
