Abstract: A printer including two adjacent printing stations has a print head attached to a carriage moved through both printing stations, with a home position for the carriage being established between the printing stations. Data describing the position of the carriage, generated with the movement of the carriage, is reset as the carriage is moved past the home position, as indicated by a position detector. If this data is corrupted or lost, the carriage is driven in a first direction until the home position is reached or until a first end of travel position is reached, whichever occurs first. At this end of travel position, a tab extending downward from the carriage comes into contact with a tab extending upward from a sliding bracket on which an idler pulley within a belt drive system, causing movement of the carriage, is mounted.

Abstract: The printer comprises a first receptacle (11) for the sheets to be printed, a sheet feeding path (27) with a printing zone (14) and a second receptacle (15) for the printed sheets. The latter is integral with an intermediate storing device having storage trays (42, 43) thus forming a group (44) which can be pivoted about a shaft (45). The sheets printed on a first face are fed by conveying members (57) into the storage trays, retained for drying, fed again into the feeding path (27) where they are reversed for printing on their second face and then arranged in the second receptacle (15). Accordingly a duplex printer is obtained, which can be used reliably with ink jet printheads, and which works dependably, has low overall dimensions and is simple and inexpensive to build.

Abstract: There is provided a printing apparatus for printing on a continuous tape. When a portion of a continuous tape having passed a thermal head is cut at a predetermined cutting position, a stepping motor is caused to stop driving the platen roller for rotation to stop feeding of the tape, and then the tape is cut off. During tape-cutting operation, the stepping motor is held in an energized state. When the printing operation is resumed after stopping the feeding and printing of the tape, the thermal head is caused to print on a portion of the tape printed by an immediately preceding printing operation by the thermal head, in an overlapping manner, by the use of identical printing data or printing data for a next line of dots.

Abstract: To maintain a high precision of a line feeding amount of a paper sheet regardless of the processing precision of a paper feed roller. Relationships between paper line feeding amounts of a paper feed roller at division positions divided into a plurality of parts with reference to an origin of a rotation angle of the paper feed roller and step counts of a paper feed motor are measured to calculate a correction value for correcting the step counts of the paper feed motor, the step counts of the paper feed motor in a line feeding operation are controlled on the basis of the correction value. When a paper feeding operation of a paper sheet whose type is except for the type of the paper sheet used in measurement is performed, a central step count of a base step count at a desired division position is calculated, and the central step count is compared with the measured central step counts of the base steps at the division positions.
