Abstract

One example includes a printer ( 110 ) having a calculator ( 120 ) to determine plot density of a printer content page ( 130 ). A controller ( 140 ) is provided to set a print parameter based on the determined plot density for the printer content page ( 130 ) to mitigate dry time for a printed output page ( 150 ).

First claim

What is claimed is:

1. A printer comprising:
a density calculator to determine a content density of data on page to be printed; and
a controller to:
receive the content density and at least one environmental variable;
determine a dry time for each swath of the page to be printed based on the content density and the at least one environmental variable;

adjust a page orientation and a print head speed for the page to be printed to mitigate a drying time of the page to be printed based on the dry time determined for each swath.

2. The printer of claim 1 , wherein the page orientation is adjusted by a 0 degree rotation, a 90 degree rotation, a 180 degree rotation, or a 270 degree rotation.

3. The printer of claim 1 , wherein the controller adjusts a paper feed delay to further mitigate the drying time.

4. The printer of claim 1 , wherein the density calculator determines the content density for an amount of ink to be employed per swath of travel of an ink head.

5. The printer of claim 1 , wherein the page to be printed is printed with the adjusted page orientation with the drying time mitigated.

6. The printer of claim 1 , wherein the density calculator determines another content density of data on another page to be printed; and
the controller determines another drying time for the another page to be printed based on the another content density and adjusts another page orientation of the another page to be printed to mitigate the another drying time.

7. The printer of claim 1 , wherein for another page to be printed, the density calculator to determine another content density of data on the another page to be printed.

8. The printer of claim 7 , wherein the controller readjusts the page orientation and the print head speed for the another page to be printed.

9. The printer of claim 7 , wherein the another content density of the another page to be printed is different from the content density of the page to be printed.

10. A method, comprising:
analyzing, by a processor, print data received by a printer, the print data with a first page orientation;
determining, by the processor, a content density of the print data on a page to be printed;
determining, by the processor, a dry time for each swath of the page to be printed based on the content density and an environmental variable; and
adjusting, by the processor, the first page orientation to a second page orientation and adjusting a print head speed variable to control a drying time of the page to be printed based on the dry time determined for each swath.

11. The method of claim 10 , further comprising causing, by the processor, the print data to be printed by the printer with the second page orientation with the drying time controlled.

12. The method of claim 10 , further comprising:
analyzing, by the processor, additional print data received by the printer, the additional print data with a third page orientation;
determining, by the processor, another content density of the additional print data on another page to be printed;
determining, by the processor, another drying time for the additional print data on the another page to be printed based on the another content density; and
changing, by the processor, the third page orientation to a fourth page orientation based on the another content density to minimize the drying time.

13. The method of claim 12 , further comprising causing the second page to be printed at the fourth page orientation after the printed page is printed to mitigate the dry time of the printed page.

14. The method of claim 10 , further comprising determining, by the processor, another content density of print data on another page to be printed.

15. The method of claim 14 , further comprising readjusting, by the processor, the page orientation and the print head speed based on the another content density calculated for the another page to be printed.

16. A system, comprising:
a memory for storing computer executable instructions associated with a computer; and
a processing unit for accessing the memory and executing the computer executable instructions, the computer executable instructions comprising:
instructions to provide a content density computation for a printed page, wherein the content density computation includes data for an amount of ink to be employed per swath of travel of an ink head on the printed page required to print content;
instructions to determine a dry time for each swath of the printed page based on the content density and an environmental variable; and
instructions to adjust a page orientation and a print head speed for the printed page to mitigate the drying time for the printed page based on the drying time determined for each swath.

17. The system of claim 16 , wherein the computer executable instructions comprise:
instructions to adjust at least one of a swath speed or a paper feed delay based on the content density to further mitigate the drying time.

18. The system of claim 16 , wherein the instructions to provide the content density computation further provide another content density calculated for another printed page.

19. The system of claim 18 , wherein the instructions to adjust the page orientation and the print head speed readjust the page orientation and the print head speed based on the another content density calculated for the another page to be printed.

20. The system of claim 18 , wherein the another content density of the another page to be printed is different from the content density of the page to be printed.
