Abstract
To provide a printing apparatus that does not degrade the printing quality even when reciprocating shifts of a film-shaped medium are continued, an ink ribbon 41 that is the film-shaped medium is laid between a supply spool 43 and a wind-up spool 44 with regions used in printing on a single printing medium formed continuously in the longitudinal direction. A counter counts the number of times an unused region in the ink ribbon 41 located in a predetermined position between the supply spool 43 and the wind-up spool 44 reciprocates and shifts between the supply spool 43 and the wind-up spool 44, and when the number of times reaches the predetermined number, the wind-up spool 44 is driven to shift the region in the wind-up direction from the printing position.
Claims6
A printing apparatus that performs printing using a film-shaped medium formed in the shape of a roll where regions used in printing on a single recording medium are continued in a longitudinal direction, comprising:
- a supply section around which a portion of a printing unused region of the film-shaped medium is wound;
- a wind-up section around which a portion of a printing used region of the film-shaped medium is wound;
- and
- a detection section that detects the number of feeding times that the printing unused region located in a predetermined position between the supply section and the wind-up section reciprocates and shifts between the supply section and the wind-up section,
- wherein when the number of feeding times reaches a predetermined number, the wind-up section is driven to shift the printing unused region in a wind-up direction from the printing position.
