Abstract

A body is provided for a portable computational device. The body includes a housing bearing a control panel to control the operation of the portable computational device. The body defines a print media exit slot, and a bay located opposite the exit slot. A print engine is mounted relative to the housing and is configured to receive a print roll cartridge so that the print roll cartridge is received within the bay. The print roll cartridge stores ink and print media. The print engine includes an elongate printhead arranged to print the ink onto the print media. A feed arrangement is configured to feed the print media from the print roll cartridge, in register with the printhead during printing, and out through the exit slot.

Claims

1. A body for a portable computational device, the body comprising:

a housing bearing a control panel to control the operation of the portable computational device, and defining a print media exit slot and a bay located opposite the exit slot;

a print engine mounted relative to the housing and configured to receive a print roll cartridge so that the print roll cartridge is received within the bay, the print roll cartridge storing ink and print media, and the print engine comprising an elongate printhead arranged to print the ink onto the print media;

a feed arrangement configured to feed the print media from the print roll cartridge, in register with the printhead during printing, and out through the exit slot; and

the print roll cartridge comprising a former, the former defining ink reservoirs for storing respective types of ink and bearing a wound length of the print media upon which the stored ink can be printed, wherein the print roll cartridge defines another print media exit slot and another feed arrangement arranged to feed a print media through the other exit slot;

wherein the print engine has a printhead assembly, the printhead assembly including;

an ink feed arrangement defining ink feed galleries which can be connected in fluid communication with respective ink reservoirs; and

the printhead arranged relative to the ink feed arrangement to print ink fed from the ink feed galleries onto the print media fed through the other exit slot.

2. A body as claimed in claim 1, wherein the printhead assembly has a capping arrangement configured to cap the printhead.

3. A body as claimed in claim 2, wherein the ink feed arrangement includes:

a casing; and

a spine which can be received within the casing to define the ink feed galleries.

4. A body as claimed in claim 1, in which the print engine includes a retainer pivotally mounted relative to the housing and configured to retain the print roll cartridge within the bay.

5. A body for a portable computational device, the body comprising:

a housing bearing a control panel to control the operation of the portable computational device, and defining a print media exit slot and a bay located opposite the exit slot;

a print engine mounted relative to the housing and configured to receive a print roll cartridge so that the print roll cartridge is received within the bay, the print roll cartridge storing ink and print media, and the print engine comprising an elongate printhead arranged to print the ink onto the print media;

a feed arrangement configured to feed the print media from the print roll cartridge, in register with the printhead during printing, and out through the exit slot;

the print roll cartridge comprising a former, the former defining ink reservoirs for storing respective types of ink and bearing a wound length of the print media upon which the stored ink can be printed, the print roll cartridge defining another print media exit slot and another feed arrangement arranged to feed the print media through the other exit slot; and

a motor assembly which can be coupled to the former and the other feed arrangement to feed the print media through the other exit slot;

wherein the print engine has a printhead assembly, the printhead assembly including;

an ink feed arrangement defining ink feed galleries which can be connected in fluid communication with respective ink reservoirs; and

the printhead arranged relative to the ink feed arrangement to print in fed from the ink feed galleries onto the printed media fed through the other exit slot.

6. A body as claimed in claim 5, wherein the other feed arrangement has three rotational rollers arranged to pinch the print media at two separate locations.
