Abstract

A system for printing an image. A printer includes a controller for motion in an X axis, components for motion in the X axis, a print head for printing image data in a swath, and a communication module for receiving image data and communications indicating that printing the swath is authorized and that printing is completed. A substrate unit includes a controller for motion in a Y axis, components for motion in the Y axis, and a communication module for receiving image data from a source. The communication module sends at least a portion of the image data to the printer.

First claim

The invention claimed is:

1. An imaging system for printing an image on a substrate, the imaging system comprising:
a plurality of printers, each printer comprising,
a separate and independent X axis motion controller for controlling motion of the printer in an X axis along a width of the substrate,
X axis motion components for implementing motion of the printer in the X axis under the control of the X axis motion controller,
a print head for printing image data in a swath along the width of the substrate and
a communication module for,
receiving the image data,
receiving communications indicating that printing of the swath is authorized, and
sending communications indicating that printing of the swath is completed, and

only one substrate unit comprising,
a separate and independent Y axis motion controller for controlling motion of the substrate in a Y axis along a length of the substrate,
Y axis motion components for implementing motion of the substrate in the Y axis under the control of the Y axis motion controller,
a communication module for
receiving image data from an image data source, and
sending at least a portion of the image data to each of the plurality of printers,
sending communications to each of the plurality of printers indicating that printing of the swath is authorized, and
receiving communications from each of the plurality of printers indicating that printing of the swath is completed,

wherein the only one substrate unit moves the substrate beneath the plurality of printers.

2. The imaging system of claim 1 , wherein each occurrence of motion in the Y axis is accomplished only in a predetermined distance.

3. The imaging system of claim 1 , wherein motion in the Y axis is accomplished in a selectable distance based at least in part upon input received by the substrate unit from the printer.

4. The imaging system of claim 1 , wherein the communication module for the printer issues only one signal, which indicates to the substrate unit that movement of the substrate in the Y axis is permissible, and the communication module for the substrate unit issues only one signal, which indicates to the printer that movement of the print head in the X axis is permissible.

5. The imaging system of claim 1 , wherein motion in the Y axis is accomplished by the substrate unit by causing the printer to move relative to the substrate.

6. A plurality of printers for printing an image on a substrate, each of the plurality of printers comprising,
an X axis motion controller for controlling motion of the printer in an X axis along a width of the substrate, and having no control of motion of either the substrate or the printer in a Y axis along a length of the substrate,
X axis motion components for implementing motion of the printer in the X axis under the control of the X axis motion controller,
a print head for printing image data in a swath along the width of the substrate, and
a communication module for,
receiving the image data,
receiving communications indicating that printing of the swath is authorized, and
sending communications indicating that printing of the swath is completed,
where authorization and all motion of the substrate in the Y axis along the length of the substrate is performed by a commonly-shared substrate unit that is not a part of any one of the plurality of printers,

wherein the commonly-shared substrate unit moves the substrate beneath the plurality of printers.

7. The plurality of printers of claim 6 , wherein each occurrence of motion in the Y axis is accomplished only in a predetermined distance.

8. The plurality of printers of claim 6 , wherein motion in the Y axis is accomplished in a selectable distance based at least in part upon input received by the substrate unit from the printer.

9. The plurality of printers of claim 6 , wherein the communication module for the printer issues only one signal, which indicates to the substrate unit that movement of the substrate in the Y axis is permissible, and the communication module for the printer receives only one signal from the substrate unit, which indicates to the printer that movement of the print head in the X axis is permissible.

10. The plurality of printers of claim 6 , wherein the communication module for the printer uses universal serial bus protocol.

11. The plurality of printers of claim 6 , wherein motion in the Y axis is accomplished by the substrate unit by causing the printer to move relative to the substrate.

12. A substrate unit for moving a substrate that is being printed, the substrate unit comprising,
a Y axis motion controller for controlling motion of the substrate in a Y axis along a length of the substrate, and having no control of motion of either the substrate or a plurality of connected printers in an X axis along a width of the substrate,
Y axis motion components for implementing motion of the substrate in the Y axis under the control of the Y axis motion controller,
a communication module for
receiving image data from an image data source, and
sending at least a portion of the image data to the plurality of connected printers,
sending communications to the plurality of connected printers indicating that printing of a swath is authorized, and
receiving communications from the plurality of connected printers indicating that printing of the swath is completed,
where the substrate unit does not directly control any movement of the substrate in the X axis across the width of the substrate,

wherein only one substrate unit moves the substrate beneath the plurality of connected printers.

13. The substrate unit of claim 12 , wherein each occurrence of motion in the Y axis is accomplished only in a predetermined distance.

14. The substrate unit of claim 12 , wherein motion in the Y axis is accomplished in a selectable distance base at least in part upon input received by the substrate unit from the plurality of connected printers.

15. The substrate unit of claim 12 , wherein each of the plurality of connected printers issues only one signal to the substrate unit, which indicates to the substrate unit that movement of the substrate in the Y axis is permissible, and the substrate unit issues only one signal to the plurality of connected printers, which indicates to the plurality of connected printers that printing of the swath in the X axis is permissible.

16. The substrate unit of claim 12 , wherein communication between the plurality of connected printers and the substrate unit is accomplished using universal serial bus protocol.

17. The substrate unit of claim 12 , wherein motion in the Y axis is accomplished by the substrate unit by causing the plurality of connected printers to move relative to the substrate.
