9. The printer of claim 1 , wherein the disengagement mechanism is configured to shield other components of the printer located on the first side of the media during the second active printing mode of operation from coming into contact with the first side of the media.
10. A method for operating a printer in two active printing modes, the method having instructions to execute on one or more processors of the printer, the method comprising:
engaging a first print head to image on a first side of media as the media passes through the printer during a first mode of operation for the printer;
engaging a second print head to image on a second side of the media as the media passes through the printer during the first active printing mode of operation for the printer in which both the first and second print heads are enabled for printing;
detecting adhesive material affixed to at least a portion of the first side of the media;
enabling a second active printing mode of operation for the printer in which the second print head is enabled for printing and the first print head is disabled for printing in response to detection of adhesive material affixed to at least a portion of the first side of the media; and
preventing at least a portion of the first print head from interfacing with the first side of the media as the media passes through the printer during the second active printing mode of operation for the printer in which the second print head is enabled for printing and the first print head is disabled for printing.
11. The method of claim 10 further comprising, automatically activating the second mode of operation within the printer as the media is interfaced to the printer by automatically detecting adhesive material on the first side of the media.
12. The method of claim 10 further comprising, automatically activating the second mode of operation in response to an event raised within the printer, the event raised by user selection of a feature indicating the first side of the media includes the adhesive material.
13. The method of claim 12 , wherein activating further includes receiving a media type selection from the user and in response thereto automatically configuring the printer to prevent the first print head from interfacing with the at least some portions of the first side of the media, the media type selection providing dimensions and locations for the at least some portions on the first side of the media.
14. The method of claim 10 further comprising thermally imaging the first and second sides of the media as the media passes through the printer during the first active printing mode of operation for the printer and thermally imaging just the second side of the media as the media passes through the printer during the second active printing mode of operation for the printer.
15. A method for operating a printer in two active printing modes, the method having instructions to execute on one or more processors of the printer, the method comprising:
engaging a first print head to image on a first side of media as the media passes through the printer during a first mode of operation for the printer;
engaging a second print head to image on a second side of the media as the media passes through the printer during the first active printing mode of operation for the printer in which both the first and second print heads are enabled for printing;
detecting adhesive material affixed to at least a portion of the first side of the media;
enabling a second active printing mode of operation for the printer in which the second print head is enabled for printing and the first print head is disabled for printing in response to detection of adhesive material affixed to at least a portion of the first side of the media; and
preventing at least a portion of the first print head from physically contacting the first side of the media as the media passes through the printer during the second active printing mode of operation for the printer in which the second print head is enabled for printing and the first print head is disabled for printing.
16. The method of claim 15 , wherein preventing at least a portion of the first print head from physically contacting the first side of the media includes providing an adhesion resistant cover between the first side of the media and the first print head to shield the first print head from the first side of the media as the media passes through the printer during the second active print mode of operation for the printer.
