Abstract
A tandem continuous paper printer includes: a first printer engine; a second printer engine; and a printer controller; and performing tandem printing by performing printing using the second printer engine on a paper that has been printed on by the first printer engine, the tandem continuous paper printer being arranged so that the first printer engine is made to print tandem check marks on the paper at check page intervals and the second printer engine is provided with a sensor detecting the tandem check marks.
Claims28
A tandem continuous paper printer comprising:
- a first printer engine;
- a second printer engine;
- and
- a printer controller, wherein tandem printing is performed by using the second printer engine on paper that has been printed on by the first printer engine,
- wherein the first printer engine, apart from performing printing of print data that make up a print job, performs printing of a tandem check mark on the paper at each page interval called “a check page interval S”,
- wherein the second printer engine has a sensor detecting the tandem check mark,
- wherein whether or not the tandem check mark printed by the first printer engine is recognized at the check page interval S is checked by using the sensor, when printing of the respective pages by the second printer engine is performed,
- wherein the second printer engine continues with the printing of the print data, if the tandem check mark is recognized by the sensor and
- wherein the printing of the print data is stopped, if the tandem check mark is not recognized by the sensor.
A tandem continuous paper printer comprising:
- a first printer engine;
- a second printer engine;
- and
- a printer controller, wherein tandem printing is performed by using the second printer engine on a paper that has been printed on by the first printer engine,
- wherein the first printer engine, apart from performing printing of print data that make up a print job, performs printing of a tandem check mark on the paper at each check page interval S,
- wherein the second printer engine has a sensor detecting the tandem check mark, and
- wherein, in performing the printing of each page, the second printer engine checks, by the sensor, whether or not the tandem check mark printed by the first printer engine exists at each check page interval S, and
- wherein if the tandem check mark is detected, the second printer engine continues with the printing of the print data while if the tandem check mark is not detected, the printing is stopped.
