A printer prints images on a printing medium having a mark. The printer includes an optical sensor, a feeding section, a controller, and a printing section. The optical sensor is operable to generate a signal based on a position of the mark of the printing medium with respect to the optical sensor. The feeding section is operable to perform feeding of the printing medium. The controller is operable to control the feeding of the printing medium based on the signal. The printing section is operabl...

A printer for printing on a recording medium with a plurality of processes includes a first processing section for making a first process on the recording media; a second processing section arranged close to the first processing section for making a second process different from the first process on the recording media on which the first process was made, thereby obtaining an image on a surface of the recording medium; and a recording medium feed path formed between the first processing section ...

There is disclosed a thermal printer for printing on webs of record members such as tags and labels. The printer has a wide print head which can print on either a wide web or on a narrow web. When printing on a narrow web, pressure contact is relieved or minimized between the portion of the platen roll and printing elements beyond the side edge of the web to minimize wear as the platen roll rotates. This is accomplished by inclining the print head and platen roll relative to each other. In order...

A printer main body is provided having a print section therein for printing and a sheet feed inlet through which paper is supplied to the print section. An automatic sheet feeder is releasably mountable substantially at position for releasably mounting a manual sheet insertion guide so that each can feed paper through the sheet feed inlet. The manual sheet insertion guide is also releasably mountable on the automatic sheet feeder, preferable at an angle at which sheets can be fed through said sh...

A printer includes a transporting block, a printing block, a positioning block, and an intermediate picking-up device. The positioning block is disposed between the transporting block and the printing block, and positions printing sheets transported by the transporting block at a predetermined location one at a time, so that they are positioned one at a time at a printing location of the printing block where printing is performed on the printing sheets. The intermediate picking-up means picks up...

Disclosed are a printer and a stacker and methods. The printer prints selectively on one or both sides of a printable web and sheets or labels are cut from the web and stacked in the stacker. The printer has an unwind mechanism that accepts and holds web rolls of different widths in center-justified relationship with respect to a print head. The printer has a spindle for mounting an ink ribbon core with a detent for center-justifying the ink-ribbon with respect to the print head.
