Transfer printer and method
A method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.
PRINTER AND METHOD
A method of operating a thermal transfer printer, the thermal transfer printer comprising first and second spool supports (3a, 4a) each being configured to support a spool of ribbon (3,4); a ribbon drive (3b, 4b) configured to cause movement of ribbon from the first spool support to the second spool support along a predetermined ribbon path; and a printhead (7). The printhead (7) is moveable towards and away from a printing surface, and, during printing, is configured to selectively transfer ink from the ribbon to a substrate as the substrate and printhead are moved relative to one another at a print speed (V-substrate). The method comprising causing relative movement between the ribbon and the printhead at a ribbon speed (V-ribbon). A relative speed of movement between the ribbon and the substrate during printing is controlled based upon a force exerted upon the ribbon by the printhead (F-printhead) during a printing operation, and/or a parameter indicative of an area of contact between a portion of the printhead and a portion of the printing surface.

Printer and method
A method of operating a thermal transfer printer, the thermal transfer printer comprising first and second spool supports each being configured to support a spool of ribbon; a ribbon drive configured to cause movement of ribbon from the first spool support to the second spool support along a predetermined ribbon path; and a printhead. The printhead is moveable towards and away from a printing surface, and, during printing, is configured to selectively transfer ink from the ribbon to a substrate as the substrate and printhead are moved relative to one another at a print speed. The method comprising causing relative movement between the ribbon and the printhead at a ribbon speed. A relative speed of movement between the ribbon and the substrate during printing is controlled based upon a force exerted upon the ribbon by the printhead during a printing operation, and/or a parameter indicative of an area of contact between a portion of the printhead and a portion of the printing surface.

Tape drive and method
A method of operating a transfer printer configured to transfer ink from a printer ribbon to a substrate which is transported along a predetermined substrate path adjacent to the printer. The printer comprises a tape drive comprising two tape drive motors, two tape spool supports on which said spools of ribbon may be mounted, each spool being drivable by a respective one of said motors. The printer further comprises a printhead being displaceable towards and away from the predetermined substrate path and being arranged to, during printing, contact one side of the ribbon to press an opposite side of the ribbon into contact with a substrate on the predetermined substrate path, and a printing surface. The printer further comprises a controller configured to control the tape drive to transport ribbon between the first and second ribbon spools. The method comprises controlling the tape drive to perform a ribbon movement in which ribbon is transported between first and second ribbon spools along a ribbon path, the ribbon path having a first length during a first part of said ribbon movement, and a second length during a second part of said ribbon movement, a transition from the first length to the second length being caused by a displacement of the printhead with respect to the printing surface, wherein control of at least one of the tape drive motors is based upon data indicative of the first and second lengths.

Printing system
A printing system includes: a printing device including a thermal head, a supplier, a winder, and a ribbon transport mechanism; and a controller configured to: transport an ink ribbon in a first direction from the supplier to the winder and heat the ink ribbon to perform printing; rewind the ink ribbon subjected to the printing in a second direction opposite to the first direction; after again receiving a print command, rewind the ink ribbon in the second direction by a first length corresponding to a length required to reach a printable speed; after the rewindings, store a second length corresponding to a length of the ink ribbon subjected to the printing upstream of the thermal head in the first direction; and feed the ink ribbon in the first direction by the stored second length.
