Claims
- 1. A printhead cartridge, comprising:
a cartridge body having a generally box like shape with front, side, top and bottom wall members for holding a supply of fluid therein; a printhead in fluid communication with said supply of fluid for ejecting fluids carried within said cartridge body; an outwardly projecting boss integrally connected to the front wall member for spacing said printhead away from the front wall member of said cartridge body and for defining a pair of printhead linear translation reversing spaces adjacent the front wall member to facilitate printing receipts in a transaction inkjet printing device.
- 2. A transaction printing device, comprising:
a base having a width dimension no greater than about 6.5 inches; a printhead cartridge stall coupled to said base and mounted for rectilinear movement along a path of travel along said width dimension, said stall being dimensioned to support from below a printhead cartridge for facilitating the ejecting of ink onto a transaction receipt having a width dimension of about 3 inches; and wherein said printhead cartridge includes:
a cartridge body having a generally box like shape with front, side, top and bottom wall members for holding a supply of ink therein; a printhead in fluid communication with said supply of ink for ejecting ink carried within said cartridge body; and an outwardly projecting boss integrally connected to the front wall member for spacing said printhead away from the front wall member of said cartridge body and for defining a pair of printhead linear translation reversing spaces adjacent the front wall member to facilitate printing onto said transaction receipt.
- 3. A printhead cartridge according to claim 1, wherein said integrally connected boss includes an elongated recess having a sufficient depth and width for receiving therein said printhead to form a pair of spaced apart debris accumulating channels.
- 4. A transaction printing device according to claim 2, wherein said integrally connected boss includes an elongated recess having a sufficient depth and width for receiving therein said printhead to form a pair of spaced apart debris accumulating channels.
- 5. A printhead cartridge according to claim 3, wherein said cartridge body includes a front wall that is integrally connected to a pair of spaced apart walls forming part of said boss.
- 6. A transaction printing device according to claim 4, wherein said cartridge body includes a front wall that is integrally connected to a pair of spaced apart walls forming part of said boss.
- 7. A printhead cartridge according to claim 5 wherein said spaced apart walls are both disposed at an angle θ relative to said front wall.
- 8. A printhead cartridge according to claim 7 wherein angle θ is between about 30 degrees and about 90 degrees.
- 9. A printhead cartridge according to claim 8, wherein a more preferred angle θ is between about 60 degrees and 90 degrees.
- 10. A printhead cartridge according to claim 9, wherein the most preferred angle θ is about 90 degrees.
- 11. A transaction printing device according to claim 6 wherein said spaced apart walls are both disposed at an angle θ relative to said front wall.
- 12. A transaction printing device according to claim 11 wherein angle θ is between about 30 degrees and about 90 degrees.
- 13. A transaction printing device according to claim 12, wherein a more preferred angle θ is between about 60 degrees and 90 degrees.
- 14. A transaction printing device according to claim 13, wherein the most preferred angle θ is about 90 degrees.
- 15. A printhead cartridge according to claim 1 wherein said integrally connected boss in plan-view with the front wall of said cartridge body has an inverted T configuration.
- 16. A transaction printing device according to claim 2, wherein said integrally connected boss in plan-view with the front wall of said cartridge body has an inverted T configuration.
- 17. A method of printing a transaction receipt having a width dimension of about three inches, comprising:
moving a printhead cartridge and a printhead wiper relative to one another in one direction along a rectilinear path of travel of substantially less than 6.5 inches for ejecting ink onto a portion of roll paper to facilitate the forming of the transaction receipt and for cleaning said printhead with said wiper; moving said printhead cartridge and said printhead wiper relative to one another in an opposite direction along said rectilinear path of travel of substantially less than 6.5 inches for ejecting ink onto another portion of the roll paper to further facilitate the forming of the transaction receipt and for cleaning said printhead with said wiper; and repeating said steps of moving and moving a sufficient number of times until the transaction receipt has been printed.
- 18. A method of printing a transaction receipt according to claim 17, wherein said first mentioned step of moving includes moving said printhead cartridge and said printhead wiper relative to one another along said rectilinear path until said wiper is disposed in an empty space adjacent a front wall portion of said printhead cartridge; and
reversing the linear translation of said print cartridge while said wiper is disposed in said empty space.
- 19. A method of printing a transaction receipt according to claim 18, wherein said second mentioned step of moving includes moving said printhead cartridge and said printhead wiper relative to one another along said rectilinear path until said wiper is disposed in an empty space adjacent a front wall portion of said printhead cartridge; and
reversing the linear translation of said print cartridge while said wiper is disposed in said empty space.
- 20. A method of printing a transaction receipt according to claim 18, wherein said second mentioned step of moving includes moving said printhead cartridge and said printhead wiper relative to one another along said rectilinear path until said wiper is disposed in another empty space adjacent a front wall portion of said printhead cartridge; and
reversing the linear translation of said print cartridge while said wiper is disposed in said empty space.
