Abstract
A piggyback recorder for use in a printer terminal having a first recorder for printing a first set of data on a document, such as a receipt document. The piggyback recorder is detachably mounted piggyback onto the first recorder, thereby providing a second recorder to the terminal for printing a second set of data on the document. The piggyback recorder comprises a piggyback print member which is capable of printing the second set of data, a mounting member for mounting the piggyback print member directly onto a first print member of the first recorder, a piggyback platen, a second mounting member for mounting the piggyback platen directly onto a first platen of the piggyback recorder, and a solenoid for providing relative movement between the piggyback print member and the piggyback platen. After the piggyback recorder is mounted on the first recorder, the controller can energize the solenoid to cause the piggyback platen to impact the piggyback print member, thereby effecting the printing of the second set of data on the document when the document is located in a printing position between the piggyback print member and piggyback platen.
