PRINTER WITH READ-AFTER-WRITE/PRINT QUALITY CHECKING Abstract of the Disclosure A printer for forms such as lottery entry tickets has a print forming device which places both alphanumeric characters and machine scannable characters on a form, responsive to input data. The print forming device or the form is moved during printing, so as to form successive characters. A scanner for reading the machine scannable characters previously printed by the print forming device is mounted such that the scanner views characters formed by the printer. The output data of the scanner is compared to data stored in memory representing the previously printed scannable characters. An error in the scanned code as compared to the stored data is interpreted as a printer failure, and the form is rejected. The device is useful for assessing quality of the previously printed scannable characters as well as the alphanumeric characters because the characters are printed with the same print elements and defective operation of a print element causes gaps in both forms of characters. The scannable characters can represent bar coded representations of the alphanumeric characters.
