Paper conveyance device and printer

A printer, comprising:

• a conveyance component configured to convey long cut paper in a longitudinal direction;
• a measuring component configured to measure a length of the long cut paper in the longitudinal direction, which is conveyed by the conveyance component;
• a first printing component configured to perform printing on one surface of the long cut paper with a printing mechanism;
• a reversal mechanism that reverses a front surface and aback surface to each other with conveying the long cut paper;
• a reversal component configured to convey the long cut paper of which the first printing component performs printing on the one surface, in the reversal mechanism;
• and
• a second printing component configured to perform printing on the other surface of the long cut paper turned upside down by the reversal mechanism, with the printing mechanism, wherein
• the reversal component conveys the long cut paper at a first speed when the measuring component measures that the length of the long cut paper is less than a predetermined length, and conveys the long cut paper at a second speed slower than the first speed when the measuring component measures that the length of the long cut paper is equal to or greater than the predetermined length.

A paper conveyance method, comprising:

• conveying long cut paper in a longitudinal direction;
• measuring a length of the long cut paper in the longitudinal direction, which is conveyed;
• reversing a front surface and a back surface to each other with conveying the long cut paper;
• and
• conveying the long cut paper in a reversal direction, wherein
• conveying the long cut paper at a first speed when the measured length of the long cut paper is less than a predetermined length, and conveying the long cut paper at a second speed slower than the first speed when the measured length of the long cut paper is equal to or greater than the predetermined length.
