Abstract

A mobile printer comprising a printer body and a printer door is provided. The printer body has a recessed area that is sized to receive a media roll. The media roll has a void interior portion that is sized to receive one or more batteries that provide power to the mobile printer. Further, the printer door is operatively coupled to the printer body. When in an open position, the printer door allows for placement of a media roll from a side of the mobile printer into the recessed area. When closed, however, the media roll is retained in place relative to the printer body and the media from the media roll is captured for printing.

Claims

1. A mobile printer comprising:

a printer body having a recessed area that defines an open space for receiving a media roll, the media roll having a void interior portion that is capable of receiving one or more batteries that power the mobile printer; and

a printer door having a printer door opening and being operatively coupled to the printer body such that the printer door;

when opened, allows for the media roll containing the one or more batteries to be placed into the open space from a side of the printer body, and

when closed, retains the media roll in place relative to the printer body, captures media from the media roll in place for printing, and permits access to the void interior portion of the media roll though the printer door opening.

2. The mobile printer of claim 1, wherein the mobile printer is a direct thermal type printer.

3. The mobile printer of claim 1, wherein the printer door is coupled to a platen roller that is spring loaded to firmly press the media against a print head.

4. The mobile printer of claim 3, wherein when the printer door is closed, the media from the media roll is captured between the platen roller and the print head that is located in the printer body.

5. The mobile printer of claim 1, further comprising an external battery accessory that is optionally coupled to the printer body to provide additional power to the mobile printer.

6. The mobile printer of claim 5, wherein the additional power provided by the external battery accessory allows for faster printing.

7. The mobile printer of claim 1, wherein a length of the media roll, when received into the open space, is parallel to a long axis of the printer body.

8. A pre-packaged cartridge for use in a mobile printer, the pre-packaged cartridge comprising:

a media roll comprising,

(1) an outer portion that comprises media on which the mobile printer prints, and

(2) an inner portion; and

one or more batteries that are used to supply power to the mobile printer, wherein the power supplied by the one or more batteries is sufficient for printing on the media of about one media roll, such that the pre-packaged cartridge, when loaded into the mobile printer, provides both the media and the power to the printer.

9. The pre-packaged cartridge of claim 8, wherein the one or more batteries are housed in a void area defined by the inner portion of the media roll.

10. The pre-packaged cartridge of claim 8, wherein the media roll is loaded into a recessed portion of a printer body from a top of the printer.

11. The pre-packaged cartridge of claim 8, wherein the pre-packaged cartridge is sent to a third party once one or more of the one or more batteries or the media are exhausted such that the one or more batteries are recharged and the media roll is rewound, and wherein once the one or more batteries are recharged and the media roll is rewound, the pre-packaged cartridge is sent to a user of the mobile printer.

12. The pre-packaged cartridge of claim 8, wherein an outer surface of the inner portion of the media roll has a shipping label that allows a user of the media roll to ship the media roll to a third party for battery recharging and media rewinding once one or more of the one or more batteries or the media are exhausted.

13. The pre-packaged cartridge of claim 8, wherein a length of the media roll is parallel to a long axis of a printer body into which the media roll is placed.

14. A side-loading mobile printer comprising:

a printer body having a long axis and a short axis;

a recessed area that is sized to receive a media roll having a length that is substantially parallel to the long axis of the printer body;

a battery spindle that houses one or more batteries that supply power to the mobile printer, the battery spindle extending from a side surface of the recessed area; and

a printer door that is operatively coupled to the printer body such that,

(1) when the printer door is open, the media roll is placed into the recessed area from a side of the printer body such that the battery spindle extends through a void interior portion of the media roll, wherein an interior surface of the media roll is sized and shaped such that there is only one way the media roll can be loaded into the recessed area of the printer body, and

(2) when the printer door is closed, the media roll is held in place relative to the printer body and media from the media roll is captured between a platen roller coupled to the printer door and a print head.

15. The mobile printer of claim 14, further comprising an external battery accessory that is removably coupled to the printer body to provide additional power to the printer, thus providing for faster printing.

16. The mobile printer of claim 14, wherein the mobile printer is a direct thermal type printer.

17. The mobile printer of claim 14, wherein features of the battery spindle and features of the media roll are arranged to prevent loading of the media roll in an incorrect orientation.

18. The mobile printer of claim 14, wherein the length of the media roll is subordinate to a long axis length of the printer body by 5% to 25%.

19. The mobile printer of claim 14, wherein the platen roller is spring loaded such that the media, when the printer door is closed, is firmly pressed against the print head, wherein the print head is housed within the printer body.
