Abstract
A dual-purpose printer for printing receipts and validating forms is provided. The printer comprises a receipt drive roller for driving paper through a receipt path, a dual-purpose roller capable of contacting the drive roller, and a validation idler roller adapted to be brought into and out of engagement with the dual-purpose roller. The receipt path is formed between the receipt drive roller and the dual-purpose roller. A validation path is formed between the validation idler roller and the dual-purpose roller. Rotation of the receipt drive roller in a first direction enables driving of paper through the receipt path. When the validation idler roller is in engagement with the dual-purpose roller, rotation of the dual-purpose roller in the first direction enables discharging of a form from the validation path.
