Abstract
A method, printer system and printer apparatus for simultaneously printing a first print medium and a second print medium, wherein, on the first print medium first information is printed that is one of: identical information to the second information and information that includes at least some information different from the second information that is printed on the second print medium.
Claims42
A receipt printer for simultaneously printing on a first medium and a second medium, comprising:
- A) a first printing unit;
- and
- B) a second printing unit;
- wherein the first and second printing units are opposed to one another and are coupled to a printer controller that controls simultaneously printing, by the first and second printing units, on the first medium and the second medium, respectively.
A printing system for simultaneously printing on a first print surface and on a second print surface, comprising:
- A) a receipt printer, coupled to a receipt producing apparatus, for simultaneously printing a receipt on said first and second print surfaces;
- and
- B) the receipt producing apparatus, coupled to the receipt printer, for sending instructions to the receipt printer for printing the receipt on said first and second print surfaces.
A method of simultaneously printing on a first print medium and on a second print medium, wherein at least some of first information printed on the first print medium is at least the same as second information printed on the second print medium.
A system for simultaneously printing first information on a first medium and second information on a second medium, wherein the second information is identical to or different from the first information, the system comprising:
- at least one print medium feed unit having at least one print medium disposed thereon, coupled to a printer controller and arranged to load the at least one print medium within a path for printing by at least one printing unit that is arranged to print on the first print medium and the second print medium;
- and
- a printer having:
- the at least one printing unit disposed therein;
- and
- the printer controller coupled to an input device, the at least one printer unit, the at least one print medium feed unit, and two feed controllers for controlling print medium feed,
- wherein the printer is arranged for printing, simultaneously, first information on the first print medium and second information on the second print medium.
A dual side printing apparatus for simultaneously printing first information on a first medium and second information on a second medium, wherein the second information is identical to or different from the first information, the apparatus comprising:
- at least one print medium feed unit having at least one print medium disposed thereon, coupled to a printer controller and arranged to load the at least one print medium within a path for printing by at least one printing unit that is arranged to print on the first print medium and the second print medium;
- and
- a printer comprising:
- the at least one printing unit disposed therein;
- and
- the printer controller coupled to an input device, the at least one printer unit, the at least one print medium feed unit, and two feed controllers for controlling print medium feed,
- wherein the printer is arranged for printing, simultaneously, first information on the first print medium and second information on the second print medium.
A printer for simultaneously printing in a first printzone and a second printzone, with the first and second printzones being on opposing sides of a print media feed path, comprising:
- A) a first printing unit dedicated to the first printzone and
- B) a second printing unit dedicated to the second printzone;
- wherein the first and second printing units are coupled to a printer controller that controls printing.
A printer for printing in a first printzone and a second printzone, with the first and second printzones being on opposing sides of a print media feed path, comprising a printing unit, coupled to a print controller, for printing in the first printzone and the second printzone.
