Accuracy and printing
- A PDF generated at exact millimetre coordinates, then printed silently — never through a browser and never scaled.
- A calibration wizard prints a millimetre grid on plain A4; you match it against a real cheque up to the light and enter the offset.
- The offset is stored per printer — switch printers and the setting is already there.
- A restricted-zone guard refuses to draw over the magnetic code line or the bank header.
- Live preview: the scanned cheque with the exact PDF that will print, overlaid.
