1. A color printer for printing specimen information onto histological specimen containers having a print zone, including:
- a specimen receiving structure configured to receive and hold histological specimen slides or cassettes having print zones;
an ink receiving structure to receive a multi-colored ink source;
a multi-colored thermal transfer print ribbon on the ink receiving structure;
a transfer receiving structure to receive a retransfer ribbon;
a retransfer ribbon on the transfer receiving structure, the retransfer ribbon having a transfer film layer;
a printing area including a thermal printhead;
a lamination area including a compliant laminator roller, wherein the laminator roller urges the retransfer ribbon onto the print zones of the slides or cassettes and deforms to conform to surface contours of the print zones and thereby cause the transfer film layer to deform and conform to surface contours of the print zones; and
an in-feed and transport to remove slides or cassettes from the specimen container receiving structure and move the slides or cassettes to the lamination area;
a port to receive print job data, wherein the print job data includes data relating to specimen information to be printed and colors of the information to be printed; and
a control system coupled to the port to receive the print job data, to cause the printhead to print the specimen information in color by heating and transfering multiple colors of ink from the print ribbon to print areas on the transfer layer of the retransfer ribbon based on the print job data, and to cause the laminator roller to transfer the printed print areas of the transfer layer to the print zones of the slides or cassettes, with the transfer layer covering the ink on the slides or cassettes.

7. A method for color printing information onto histological specimen containers, including:
-
printing an ink specimen information image onto a transfer layer of a retransfer ribbon, including causing a thermal printhead to print specimen information in color by heating and transferring multiple colors of ink from a multi-colored thermal transfer print ribbon to print areas on the transfer layer of the retransfer ribbon; and transferring the transfer layer with the specimen information image onto a print zone of a histological specimen slide or cassette having surface contours, with the transfer layer covering the ink on the slides or cassettes, including engaging the retransfer ribbon with a compliant laminator roller to urge the retransfer ribbon onto the print zones and to deform the laminator roller to conform to surface contours of the print zones and thereby cause the transfer layer to deform and conform to the surface contours of the print zones.
