Abstract
A sheet is conveyed with no slack between a first conveying path and a second conveying path, thus allowing a high-quality image to be printed on the sheet and suppressing a possible sheet jam. A conveying path with a changeable conveying path length is provided between a first conveying path including a pair of downstream side conveying rollers and a pair of downstream side conveying rollers and a second conveying path including a pair of downstream side conveying rollers and a pair of downstream side conveying rollers.

A printing apparatus comprising:
- a first conveying unit configured to convey a sheet through a first conveying path;
- a first print unit configured to print an image on the sheet in the first conveying path;
- a second conveying unit configured to convey the sheet through the second conveying path;
- a second print unit configured to print an image on the sheet in the second conveying path;
