A printer with a cap mechanism. The printer comprises a print head comprising a nozzle, a cap module comprising a cap and a hole, and a positioning module comprising a pin. When the print head moves in a first direction to push the positioning module, the pin escapes from the hole, whereby the cap module moving in a second direction enables the cap to cover the nozzle. When the print head moves in a direction opposite to the first direction, the pin enters the hole enabling the cap module to maintain a predetermined distance from the print head.
