Abstract
Alignment mark 5 is printed by printer 30 during the same operation in which bar code 3 is printed. Subsequent alignment is by the optical scanner 32 centering on mark 5. In a specific application a factor relating to the vertical position of scanner 32 to printer 30 is obtained by scanning mark 5 shortly after it is printed. This factor is used to position the scanner 32 to read for errors after a line of code 3 is printed.
