void drawBarcode(String str,int align)
void printText();
void printImageFile(String filePath,int align,bool isAutoFeed);
void printImage(Uint8List img ,int align,bool isAutoFeed);

void drawNewLine();
void drawOneLine([int? fontSize]);
void drawCustom(String str,int fontSize,int align);
void drawLeftRight(String left,String right,int fontSize);
void drawImage(String path);
void drawQrCode(String str, int align, [int? height]);
Example #
Uint8List bytes = await _getAssetImage('assets/images/logo.png');
Gcprinter.printImage(bytes, Gcprinter.alignCenter, false);
Gcprinter.drawText("1 x", Gcprinter.fontSmallBold, "test", Gcprinter.fontSmallBold, "65.00", Gcprinter.fontSmallBold);
Gcprinter.drawText("option1", Gcprinter.fontDefault, "", Gcprinter.fontDefault, "60.00", Gcprinter.fontDefault);
Gcprinter.drawText("option2", Gcprinter.fontDefault, "", Gcprinter.fontDefault, "5.00", Gcprinter.fontDefault);
Gcprinter.drawBarcode("test123", Gcprinter.alignCenter,Gcprinter.barcodeQrCode);
Gcprinter.drawText("",0,"test123",Gcprinter.fontDefault,"",0);
Gcprinter.printText(true);
Different implementations of the same example #
Uint8List bytes = await _getAssetImage('assets/images/logo.png');
Gcprinter.printImage(bytes, Gcprinter.alignCenter, false);
Gcprinter.drawText("1 x", Gcprinter.fontSmallBold, "test", Gcprinter.fontSmallBold, "65.00", Gcprinter.fontSmallBold);
Gcprinter.drawLeftRight("option1", Gcprinter.fontDefault, "60.00", Gcprinter.fontDefault);
Gcprinter.drawLeftRight("option2", Gcprinter.fontDefault, "5.00", Gcprinter.fontDefault);
Gcprinter.drawQrCode("test123", Gcprinter.alignCenter);
Gcprinter.drawCustom("test123",Gcprinter.fontDefault,Gcprinter.alignCenter);
Gcprinter.printText(true);
