摘要： A printer accurately controls the passage of print media therethrough and maintains the print media taut as the print media passes through a printing zone while the media is printed by an ink jet printer. The print media sheet is preferably carried by a rotating drum in a first direction through the printing zone, with the drum being reversed to cause the exiting of the print media sheet from the printer. A pressure fixing or fusing apparatus may be positioned to flatten ink spots on the print media as the print media exits from the printer. The pressure fixing or fusing mechanism is preferably used in the case of a hot-melt or phase-change ink jet printer.

摘要： A thermal printer accepting an ink ribbon cartridge includes a chassis, a thermal head secured to the chassis and a platen roller which is rotatably supported in the chassis and swingably movable relative to the thermal head. The platen roller is rotated by a first platen driving mechanism and is moved toward and away from the thermal head by a second platen driving mechanism. When the platen roller is moved to contact the thermal head via an ink ribbon intervened therebetween, an image is printed on a printing medium fed between the platen roller and the ink ribbon. The printer accomplished aligned overprinting on the printing medium via a paper supply mode, a printing mode, a paper retract mode and a paper discharge mode effected by the first and second platen driving mechanisms.
