Abstract

A camera device includes a replaceable print roll. The print roll includes an ink reservoir section storing respective types of ink. A validation apparatus is configured to validate the replaceable print roll. A printer is configured to print an image on print media upon validation of the print roll. The printer includes an ink supply unit defining a channel from which ink supply passages extend. The printer is configured to receive the ink within the ink supply passages. An ink ejection printhead is located in the channel and includes sets of ink inlets with each set being configured to receive a respective type of ink from the ink supply passages. A roller assembly is arranged to transport the print media in register with the printhead during printing of the image.
