Multicolored thermal printer, ribbon and media
View Patent ↗Printing systems and methods are described for multicolored thermal printing simultaneously using a plurality of thermal printing technologies to achieve multicolored output. In one configuration, a dual thermal technology thermal printer includes a single thermal media ribbon printing subsystem using a multi-temperature thermal print head capable of producing grayscale or varying intensity marking on a multi-intensity direct contact thermal media such as a grayscale media.
1. A dual technology thermal printer comprising:
a printer housing containing a thermal print head controller and a thermal print head operatively connected to the controller;
the printer housing containing a feeding subsystem for feeding direct thermal media past the thermal print head;
a thermal transfer ribbon spooling subsystem operatively connected to the printer housing for feeding a thermal transfer ribbon between the thermal print head and the direct thermal media, wherein
the thermal transfer ribbon comprises an ink that is deposited at a temperature lower than a substantial activation temperature associated with the direct thermal media.
2. The printer of claim 1 wherein the thermal print head comprises a multi-heat-level thermal print head capable of printing grayscale direct thermal media.
3. The printer of claim 2 wherein the direct thermal media is a roll of grayscale media.
4. The printer of claim 1 wherein the thermal transfer ribbon comprises a fluorescent red ink.
5. A dual technology thermal printer comprising:
a printer housing containing a thermal print head controller, a first thermal print configured to mark media operatively connected to the controller and a second thermal print head configured to mark media operatively connected to the controller;
the printer housing containing a feeding subsystem for feeding direct thermal media first past the first thermal print head and then past the second thermal print head;
a thermal transfer ribbon spooling subsystem operatively connected to the printer housing for feeding a thermal transfer ribbon between the second thermal print head and the direct thermal media, wherein,
the thermal transfer ribbon comprises an ink that is deposited at a temperature lower than a substantial activation temperature associated with the direct thermal media.
6. The printer of claim 5 wherein the first thermal print head comprises a multi-heat-level thermal print head capable of printing grayscale direct thermal media.
7. The printer of claim 6 wherein the second thermal print head comprises a single-heat-level thermal print head capable of depositing ink from the thermal transfer ribbon.
8. The printer of claim 6 wherein the direct thermal media is a roll of grayscale media.
9. The printer of claim 5 wherein the thermal transfer ribbon comprises a fluorescent red ink.
10. The printer of claim 5 wherein the controller is configured to control the first multi-heat-level thermal print head and the second single-heat-level thermal print head.
11. A method for printing using a dual technology thermal printer comprising:
feeding multiple intensity direct thermal media through the dual technology thermal printer having at least one multiple heat level ribbon thermal print head and single color thermal ribbon; and
controlling the at least one multiple heat level print head to selectively mark the appropriate intensity on the direct thermal media and to selectively transfer the ribbon ink, wherein,
controlling the at least one multiple heat level print head comprises simultaneously selectively marking the appropriate intensity on the direct thermal media and selectively transferring the ribbon ink.
12. The method of claim 11 wherein the multiple heat level ribbon thermal print head may be driven at a temperature that causes ink from the thermal ribbon to transfer without appreciably marking the multiple intensity direct thermal media.
13. The method of claim 11 wherein the multiple intensity direct thermal media is fed from a roll of thermal media label stock.
