Abstract

A printing and display device for use with an external computer. The printing and display device includes a flat panel display for displaying images from the external computer; a printer including a printhead for printing onto paper; a display data connection for selectively connecting to the external computer to receive display data used to provide the images displayed; a print data connection for selective connection to the external computer to receive print data from the external computer; and a rear cover molding enclosing therein the flat panel display. The rear cover molding includes an aperture for receiving therein an external ink cartridge.

Claims

1. A printing and display device for use with an external computer, the printing and display device comprising:

a flat panel display for displaying images from the external computer;

a printer including a printhead for printing onto paper;

a video socket adapted to engage with a video plug and video cable from the external computer to receive a video signal used to provide the images displayed;

a print data connection for selective connection to the external computer to receive print instructions from the external computer;

a rear cover molding enclosing therein the flat panel display; and

an ink delivery bus provided within the rear cover molding, wherein,

the rear cover molding includes an aperture for receiving therein an external ink cartridge,

the aperture facilitates coupling of the external ink cartridge with the ink delivery bus, and

the ink delivery bus includes one or more fluid ports for engaging with the external ink cartridge, each of the one or more fluid port including a hollow needle adapted to penetrate a seal of the external ink cartridge.

2. A printing and display device as claimed in claim 1, wherein the ink delivery bus further includes an electrical contact, the electrical contact for connecting with an integrated circuit provided on the external ink cartridge to facilitate communication between the printing and display device and the external ink cartridge.

3. A printing and display device as claimed in claim 1, wherein the printer includes at least two printheads, the printheads being disposed on either side of a path through which print media is fed for printing.

4. A printing and display device as claimed in claim 1, wherein the print data connection includes a wireless receiver for receiving the print data and/or the display data.

5. A printing and display device as claimed in claim 1, wherein the print data connection is a Universal Synchronous Bus (USB) connection.

6. A printing and display device as claimed in claim 1, further including a paper feed mechanism for feeding the paper to the printhead for printing.

7. A printing and display device as claimed in claim 6, wherein the paper feed mechanism is configured to position the paper substantially parallel with respect to a plane defined by the flat panel display.

8. A printing and display device as claimed in claim 7, wherein the paper feed mechanism includes a paper separator for feeding a single sheet of paper to the printhead from a stack of sheets of paper.

9. A printing and display device as claimed in claim 1, wherein the printer is a process color printer.

10. A printing and display device as claimed in claim 1, wherein the printer is an inkjet printer.

11. A printing and display device as claimed in claim 1, wherein the printer is a page-width printer spanning the length of a lower edge of the flat panel display.

12. A printing and display device as claimed in claim 1, wherein the flat panel display measures at least 14 inches on the diagonal.

13. A printing and display device as claimed in claim 1, further including a curved paper guide disposed adjacent a lower edge of the flat panel display and downstream from the printhead, the curved paper guide adapted to urged media exiting from the printhead horizontally and towards a front of the flat panel display.

14. A printing and display device as claimed in claim 1, wherein the flat panel display is of one of the following types:

a. Liquid Crystal Display (LCD);

b. Organic Light Emitting Diode (OLED)

c. Field Emission Display (FED)

d. Plasma Display Panel (PDP).

15. A printing and display device as claimed in claim 1, wherein the printhead is configured to receive halftoned print data to be printed onto the print media.

16. A printing and display device as claimed in claim 1, further including a halftoning unit for generating halftoned image data and supplying the halftoned image data to the printhead for printing.
