AI Technical Summary
Technical Problem
In existing printing apparatuses, misalignment or variation in conveyance rollers can disrupt the balance between the holding force of the first roller and the conveyance force of other rollers, leading to skew in printing media such as label paper.
Method used
A printing apparatus with a tension applying section that applies tension to the printing medium in a direction different from its transport direction, controlled by a switching section and a control section to manage this tension, and includes a mechanism to detect and adjust for skew using strain gauges and a motor to rotate a tension lever.
Benefits of technology
The solution effectively reduces skew in the printing medium by applying controlled tension, enhancing the stability and alignment of the printing process.

Abstract
To provide a printing apparatus that can suppress skew in the printed medium. [Solution] The printing apparatus comprises a holding section in which a printing medium is stored, a transport roller for transporting the printing medium pulled out from the holding section, a print head located downstream of the transport roller in the transport path of the printing medium, a tension applying section that contacts the printing medium between the holding section and the transport roller in the transport path of the printing medium and applies tension to the printing medium in a direction different from the transport direction of the printing medium, a switching section that switches between a state in which the tension applying section applies tension to the printing medium and a state in which it does not apply tension, and a control section that controls the switching section.
