1final profile = await CapabilityProfile.load(); 2final printer = NetworkPrinter(paper, profile); 3final PosPrintColumn column1 = PosPrintColumn( 4 text: 'Item 1', 5 width: 2, 6 styles: PosStyles(align: PosAlign.left));
1printer.printQrCode('YourQRCodeText');
1printer.printReceipt();
Now, imagine you want to add a bonus feature to your Flutter application – say, a feature allowing users to print receipts via their Bluetooth printers. Or, perhaps your Flutter app requires users to print QR codes from a WiFi printer. The beauty of esc pos utils is that it caters to all such needs, providing a comprehensive, goof-proof solution to address your printing requirements.
ESC/POS, or Epson Standard Code for Printers, is a command system created by Epson to define the method for formatting print data from a computer or device to an Epson receipt printer—the coding comprised of simple yet powerful commands that optimized printer functionality and improved performance.
Given Flutter's growing popularity and excellent cross-platform support, many developers want to incorporate the 'esc pos' system into their apps. This makes serving functionalities like printing QR codes or receipts with a thermal printer simpler and more efficient.
