Printing associated plots in registration
In one example, a print job is received. The print job includes a first plot to be printed on a first side of a media, and a second plot to be printed on a second side of the media in registration with the first plot. The first plot and a fiducial mark are caused to print on the first side, the fiducial mark being a known distance from the first plot and including an identifier for the second plot. In response to detecting the identifier via a sensor and measuring a distance to the fiducial mark to discern a reference for printing the second plot, the second plot is caused to print on the second side in registration with the first plot.
1. A method to print associated plots in registration on first and second sides of a media, comprising:
receiving a print job including a first plot to be printed the first side, and a second plot to be printed on the second side in registration with the first plot;
causing printing of the first plot and a fiducial mark on the first side, the fiducial mark
being a known distance from the first plot, and
including an identifier, wherein the identifier is data that indicates which of a plurality of plots in a memory location is the second plot to be printed on the second side;
causing printing of the second plot on the second side in registration with the first plot in response to
detecting via a sensor the identifier, and
measuring a distance to the fiducial mark to discern a reference for printing the second plot.
2. The method of claim 1 , wherein the distance to the fiducial mark is measured by the sensor.
3. The method of claim 1 , wherein the distance to the fiducial mark is measured by a sensor other than the sensor that detects the identifier.
4. The method of claim 1 , wherein the identifier comprises a barcode.
5. The method of claim 1 , wherein the identifier is an identifier generated at a computing device distinct from a printer device and an internal processor of the printer device.
6. The method of claim 1 , wherein the identifier is an identifier generated at a printer.
7. The method of claim 1 , wherein a width of the fiducial mark is substantially the same as a width of the first plot.
8. The method of claim 1 , wherein the identifier comprises a pointer to the memory location for the second plot.
9. The method of claim 1 , wherein the identifier comprises a tag with an address to the memory location for the second plot.
10. The method of claim 1 , wherein the identifier indirectly identifies the second plot via a lookup table.
11. The method of claim 1 , wherein a same print mechanism prints the first and second plots.
12. The method of claim 1 , wherein causing printing of the second plot on the second side further comprises confirming that a condition precedent relating to the media is met.
13. The method of claim 1 , further comprising causing inversion of the media after printing of the first plot to cause
the second side to be in a position to be printed upon, and
the fiducial mark to be exposed to a sensor as the media is advanced.
14. The method of claim 13 , wherein causing inversion of the media comprises:
causing the media to be taken up on a take-up device during printing of the first plot; and
causing positioning of the take-up device to supply the media during printing of the second plot.
15. A system to print associated plots in registration on first and second sides of a media, comprising:
a receipt module to receive a print job including a first plot to be printed the first side, and a second plot to be printed on the second side in registration with the first plot;
a first side module to cause printing of the first plot and a fiducial mark on the first side, the fiducial mark
being a known distance from the first plot, and
including an identifier, wherein the identifier is data that indicates which of a plurality of plots in a memory location is the second plot to be printed on the second side;
a second side module to cause printing of the second plot on the second side in registration with the first plot in response to
detecting, via a sensor, the identifier, and
measuring a distance to the fiducial mark to discern a reference for printing the second plot.
16. The system of claim 15 , wherein the identifier comprises a two dimensional barcode.
17. The system of claim 15 , wherein the identifier provides the memory location for the second plot.
18. The system of claim 15 , wherein the identifier indirectly identifies the second plot via a lookup table.
19. The system of claim 15 , further comprising an inversion module to cause inversion of the media after printing of the first plot to cause
the second side to be in a position to be printed upon, and
the fiducial mark to be exposed to the sensor as the media is advanced.
20. A non-transitory computer-readable storage medium containing instructions to print associated plots in registration on first and second sides of a media, the instructions when executed by a processor causing the processor to:
receive a print job including a first plot to be printed the first side, and a second plot to be printed on the second side in registration with the first plot;
cause printing of the first plot and a fiducial mark on the first side, the fiducial mark
being a known distance from the first plot, and
including an identifier, wherein the identifier is data that indicates which of a plurality of plots in a memory location is the second plot to be printed on the second side;
cause inversion of the media after printing of the first plot to cause
the second side to be in a position to be printed upon, and
the fiducial mark to be exposed to a sensor as the media is advanced;
cause printing of the second plot on the second side in registration with the first plot in response to
detecting, via the sensor, the identifier,
measuring, via the sensor, a distance to the fiducial mark to discern a reference for printing the second plot, and
confirming that a condition precedent relating to the media is met.
