A printer of the present invention includes a first and a second tray each being movable between a full-closed position and an open position. When the operator moves the first tray in the opening direction, the first tray forces the second tray located on the locus of movement of the first tray in the opening direction, uncovering a first and a second opening at the same time. When the operator moves the second tray in the closing direction, the second tray forces the first tray located on the l...

There is provided a printer including a grip portion that becomes a handhold in moving the printer, and the grip portion is formed of a part of a jacket of the printer.

A printer includes a line thermal head, a platen roller for holding a paper between the platen roller and the line thermal head and feeding the paper, a cutter, including a movable blade and a fixed blade, for cutting printed paper, and a cutter driving mechanism for driving the movable blade. At least one of the line thermal head and the platen roller can be moved from a first position for printing to a second position for removing a paper jam, and one of the movable blade and the fixed blade i...

A printer comprises for forming an image on a surface of a recording medium includes a preprocessing means for preprocessing the surface of the recording media to form an image on the surface of the recording media; post-processing device for post-processing the surface of the recording medium preprocessed by the preprocessing device; a recording medium feed path formed between the preprocessing means and the post-processing means; a first feed device arranged on an upstream side of the recordin...
