Background
The printing modes of the ink jet printer are classified into a scanning type and a one-pass type. The scanning type printing mode means that the printing medium in the printing area is static during printing, the printing is scanned and printed along the transverse direction through the printing trolley, and the printing medium moves longitudinally and stepwise relative to the printing trolley after the scanning is finished so as to prepare for the next transverse scanning and printing, so that the printing of the whole pattern is completed in this way; the one-pass printing mode means that the printing trolley is still and the whole pattern is printed by the longitudinal movement of the printing medium. The scanning type printing comprises roll-to-roll type ink-jet printing and flat-table type ink-jet printing, in the roll-to-roll type ink-jet printing, the transverse scanning of a printing trolley and the longitudinal stepping of a printing medium are used for completing the printing of patterns, in the printing process, the printing medium in a printing area needs to keep enough tension to enable the printing medium to be flat and not deformed, so that a printing finished product with higher quality is obtained, and the influence of the control precision of stepping motion on the printing quality is great. In the related art, a printing medium drives a tape dispensing adhesive type and a friction drive type. The conduction band paste type conduction band glue and the printing medium have compatibility problems, cannot be applied for a long time and are high in price; in the friction driving type, in the current application, the friction force between the rubber roller and the printing medium intermittently pushes the printing medium forwards in a stepping manner, and the friction force of the rubber roller and the printing medium are combined with the action of a front tension roller to overcome the defect that the suction force at the adsorption air suction platform drives the printing medium to move. Due to the characteristic of softness of the printing medium, the printing medium is deformed microscopically and slips relatively due to the change of friction force between the printing medium and the roller body in the driving process, so that the movement precision of each time is inconsistent, and the problem of printing output quality is caused.

In the prior art, the vacuum driving roller is arranged, so that the printing medium is adsorbed on the vacuum driving roller and cannot generate relative displacement, and the stepping driving precision of the printing medium is kept constant. However, this technique has the following problems: the printing medium is released from the unreeling mechanism and placed above the air suction platform through the transition roller, and moves in a stepping mode under the action of pulling force of the vacuum driving roller, the transition roller comprises a first guide roller, a driving roller and a second guide roller, the printing medium passes through the first guide rail, the printing medium is conveyed to the second guide roller under the driving of the driving roller and conveyed to the air suction platform under the action of the second guide roller, although the printing medium is adsorbed on the vacuum driving roller and cannot generate displacement towards the direction of the reeling mechanism, the driving roller and the second guide roller have certain inertia under the pulling of the printing medium, when the vacuum driving roller stops rotating, the driving roller and the second guide roller cannot stop rotating in time, so that the stepping precision of the printing medium in front of the vacuum driving roller cannot be controlled, the stepping distance of the printing medium is easy to be too long, and the printing medium generated by the driving roller cannot be controlled to be subjected to small due to tension on the air suction platform in front of the vacuum driving roller The concave-convex deformation of the printing head affects the printing quality.
