Abstract
An apparatus and method for printing postal indicia and similar images. The apparatus includes two print stations and an ink jet printhead transportable between the stations. The printhead forms images on a transfer roller located at each of the stations and the image is then transferred from the roller to a substrate. At the second station the transfer roller is incorporated in a detachable roller and is used to print remotely located substrates.
Claims13
A method for printing an image on a substrate, said method comprising the steps of:
- a) providing a first station for temporary attachment of a transportable transfer roller;
- b) providing an image forming mechanism responsive to signals representative of images to be printed proximate to said first station to form corresponding reversed images on a transfer roller attached to said first station;
- c) attaching said transfer roller to said first station;
- d) rotating said transportable transfer roller synchronously with operation of said image forming mechanism as said mechanism forms a reverse of said image on said transfer roller;
- e) detaching said transfer roller from said first station
- f) transporting said transportable transfer roller to said substrate;
- and
- g) applying said transportable transfer roller to said substrate to print said image.

An apparatus for printing an image on a substrate, comprising:
- a) a transportable transfer roller;
- b) a first station for temporary attachment of said transportable transfer roller;
- c) a second station, said second station including a fixed transfer roller;
- d) an image forming mechanism responsive to signals representative of images to be printed to form corresponding reversed images on said transfer roller attached to said first station, said image forming mechanism being positioned proximate to said first station;
- e) means for transporting said image forming mechanism between said first and second stations;
- and
- f) drive means for rotating said transportable transfer roller synchronously with operation of said image forming mechanism to form a reverse of said image when said transportable transfer roller is attached to said first station.
