Abstract

A keyboard for a computer system is provided. The keyboard comprises a housing having an upper surface defining an opening for a plurality of keys, a printer assembly positioned on a print media transport path within the housing, a print media entry slot defined in a first side of the housing, a print media ejection slot defined in a second side of the housing opposite the first side, a printer controller circuit positioned within the housing; and a serial bus for communicating with the computer system. The serial bus is operatively connected to the printer controller circuit. In use, print commands are received by the printer controller circuit from the computer system via the serial bus.

Claims

1. A keyboard for a computer system, said keyboard comprising:

a housing having an upper surface defining an opening for a plurality of keys;

a printer assembly positioned on a print media transport path within the housing;

a print media entry slot defined in a first side of the housing;

a print media ejection slot defined in a second side of the housing opposite the first side;

a printer controller circuit positioned within the housing;

a serial bus for communicating with the computer system, said serial bus being operatively connected to the printer controller circuit;

a belt-and-roller transport assembly disposed to transport print media along the transport path; and

a planar member biased against the belt-and-roller transport assembly to maintain planarity of print media in use;

wherein print commands are received by the printer controller circuit from the computer system via the serial bus.

2. The keyboard of claim 1, wherein the keys are arranged to engage key switches of the keyboard circuit board.

3. The keyboard of claim 1, wherein the planar member and the belt-and-roller transport assembly are located beneath the keyboard circuit board.

4. The keyboard of claim 1, wherein the printer assembly comprises a pagewidth ink jet printhead.

5. The keyboard of claim 4, wherein the printer assembly includes a plurality of galleries each in fluid communication with the printhead and dedicated to store a different color ink.
