All text aligned to right side
There is no space between each row

Using HOIN 80mm POS Printer

PosStyles rightStyles=PosStyles(align: PosAlign.right, fontType: PosFontType.fontA); bytes += generator.row( [ PosColumn( text: 'Qty', width: 3,), PosColumn( text: 'Item', width: 3,), PosColumn( text: 'Price', width: 3,styles:rightStyles ), PosColumn( text: 'Total', width: 3,styles:rightStyles), ], );
