Abstract

The present invention embraces printers such as hand-held printers and mobile/portable printer. One exemplary embodiment includes “print as you glide” (PAYG) devices. Such printers may comprise a modular print engine that is removable from the printer and may allow a user to easily access and load the ribbon in the mobile print engine. The modular print engine may comprise a modular print head and an encoder that may determine the movement of the print head relative to a stationary media. When a printer is pressed against the media, the print head's burn line may be resting on the media. When the printer is stationary relative to the media, the encoder may not trigger the printing. Once PAYG is being slid or glided across the media, the encoder may start to rotate and then send a signal to a processor, causing the printer to start printing.

First claim

The invention claimed is:

1. A device, comprising:
a modular print engine comprising a modular print head and a media encoder;
a printed circuit board (PCB) comprising a processor; and
a main body comprising the modular print engine and the printed circuit board;
wherein the main body comprises a cover portion to allow the modular print engine to be removed from the main body and to allow a user to load a new ribbon in the modular print engine;
wherein the main body comprises a handle portion to allow the user to hold the device and to facilitate movement between the modular print engine and a media; and
wherein, in response to the modular print engine and the media being in contact and the movement between the modular print engine and the media, the modular print engine prints on the media.

2. The device according to claim 1 , wherein, in response to the device pressing against the media, a burn line of the modular print head presses a ribbon against the media.

3. The device according to claim 1 , wherein, in response to the device starting to slide across to the media, the media encoder sends a signal to the processor with an instruction to start a print operation.

4. The device according to claim 3 , wherein, the media encoder generates the signal based on a rotation in the media encoder caused by the device sliding across the media.

5. The device according to claim 4 , wherein the modular print engine comprises a rotating arm with a spring mechanism, associated with the media encoder.

6. The device according to claim 1 , wherein the cover portion of the main body further allows the modular print engine to be secured within the main body.

7. The device according to claim 1 , wherein, based on a direction of rotation of the media encoder, the modular print engine either stops printing, or continues printing.

8. The device according to claim 1 , comprising a fine needle opening located at one end of the device, wherein, when an adapter plug is inserted in the fine needle opening, silicon rubber of the adapter plug conforms to a shape of the adapter plug and creates a seamless water proofing seal between the adapter plug and the device.

9. The device according to claim 1 , wherein, the main body comprises a battery.

10. The device according to claim 1 , wherein, the modular print head is removable from the modular print engine.

11. A printing system comprising:
a main body comprising:
a printing circuit board (PCB) positioned in an upper portion of the main body; and
a modular print engine positioned in a lower portion of the main body to allow a user to load a new ribbon in the modular print engine,

wherein the main body comprises a cover portion to allow the modular print engine to be removed from the main body;
wherein the main body comprises a handle portion to allow the user to hold the main body and to facilitate movement between the modular print engine and a media; and
wherein, in response to the modular print engine and the media being in contact and the movement between the modular print engine and the media, the modular print engine prints on the media.

12. The printing system of claim 11 , wherein in response to the printing system pressing against the media, a burn line of the modular print head presses a ribbon against the media.

13. The printing system of claim 11 , wherein the main body further comprises a media encoder, and the PCB further comprises a processor, and wherein in response to the printing system starting to slide across to the media, the media encoder sends a signal to the processor with an instruction to start a print operation.

14. The printing system of claim 13 , wherein the media encoder sends the signal based on a rotation in the media encoder caused by the printing system sliding across the media.

15. The printing system of claim 14 , wherein based on a direction of the rotation of the media encoder, the modular print engine either stops printing, or continues printing.

16. The printing system of claim 11 , wherein the modular print engine comprises a rotating arm with a spring mechanism, associated with a media encoder, wherein the media encoder is comprised within the main body.

17. The printing system of claim 11 , wherein the cover portion of the main body further allows the modular print engine to be secured within the main body.

18. The printing system of claim 11 , further comprising a fine needle opening located at one end of the printing system, wherein, when an adapter plug is inserted in the fine needle opening, silicon rubber of the adapter plug conforms to a shape of the adapter plug and creates a seamless water proofing seal between the adapter plug and the printing system.

19. The printing system of claim 11 , wherein the main body comprises a battery.

20. The printing system of claim 11 , wherein the PCB comprises a processor to control a printing operation of the modular print engine.
