The push tractor is installed at the paper entrance and pushes paper into the printer. On the other hand, the pull tractor is installed at the paper exit and pulls paper out of the printer mechanism.

the paper entrance and pushes paper into the printer. On the other hand, the pull tractor is installed at the
paper exit and pulls paper out of the printer mechanism. As a result, the paper tension unit is not required.
