A printing apparatus includes a mounting plate, a driving module attached to the mounting plate, a driven module secured to the mounting plate, an endless belt connecting the driving module and the driven module, a resisting member slidably engaged with the driven module, and an adjusting member rotatably secured to the mounting plate and pressing the resisting member on the driven module. The adjusting member can be loosened and tightened. When the adjusting member is loosened, the driven module is movable relative to the mounting plate along a first direction by urging of the endless belt. When the adjusting member is tightened, the driven module is still movable relative to the mounting plate along a second direction opposite to the first direction, by pressure from the resisting member. |
