To Reproduce
Code snippet to reproduce the behavior:

  final Uint8List imageData = await rootBundle.load('assets/images/test.png').then((value) => value.buffer.asUint8List());

  final pageFormat = PdfPageFormat.letter.copyWith(
    marginLeft: 2 * PdfPageFormat.mm
  );

  pdf.addPage(
    pw.Page(
      pageFormat: pageFormat,
      build: (pw.Context context) {
        return pw.Stack(
          children: [
            pw.Positioned(
              left: 28 * PdfPageFormat.mm,
              top: 10 * PdfPageFormat.mm,
              child: pw.Image(pw.MemoryImage(Uint8List.fromList(imageData)),
                  width: 4 * PdfPageFormat.mm),
            ),
            pw.Positioned(
              left: 35 * PdfPageFormat.mm,
              top: 10 * PdfPageFormat.mm,
              child: pw.Image(pw.MemoryImage(Uint8List.fromList(imageData)),
                  width: 4 * PdfPageFormat.mm),
            ),
            pw.Positioned(
              left: 41 * PdfPageFormat.mm,
              top: 10 * PdfPageFormat.mm,
              child: pw.Image(pw.MemoryImage(Uint8List.fromList(imageData)),
                  width: 4 * PdfPageFormat.mm),
            )
          ],
        );
      },
    ),
  );
  // Print preview
  final result = await Printing.layoutPdf(
    onLayout: (PdfPageFormat format) async => pdf.save(),

  );

Expected behavior
Print preview should show the image you should be printing
