A button product fabricating device is configured to fabricate a button product by connecting a front member and a back member. The button product fabricating device includes: a printer configured to perform printing on a printing medium; a die set configured to connect the front member and the back member; and a conveyor configured to convey the printing medium onto the front member along a conveying path from the printer toward the die set. The conveyor includes: a plurality of conveying rollers; and a one-way clutch. The one-way clutch is configured to: transmit a drive force to the conveying rollers when rotating in a first rotation direction; and not to transmit the drive force to the conveying rollers when rotating in a second rotation direction which is a direction opposite to the first rotation direction.

An inspection device includes: a holder that holds an inspection medium that is a medium on which an image is formed; an image sensor that reads the image on the inspection medium; and a controller that inspects the inspection medium by comparing, with a reference image, an inspection image obtained by performing image processing on a read image read by the image sensor. The holder has a non-plane surface as a holding surface, and the controller changes one or both of the inspection image and the reference image based on a transparency of the medium.

A printer unit includes a device housing including a transport roller and a spreading roller, a roller drive mechanism that is attached to the device housing and includes a drive transmission gear train that drives the transport roller and the spreading roller, and a cover member that covers the roller drive mechanism. The roller drive mechanism includes a gear plate separate from the cover member. The gear plate is fixed to the device housing at two locations and is formed in a plate shape that pivotally supports at least one of rotational shafts of the drive transmission gear train.

A printer includes a media path along which labels are movable, and a printhead positioned along the media path. At least a part of the media path includes a side structure defining a first side of the part of the media path and a media edge guide for defining a second side of the part of the media path, wherein the media edge guide is movable so as to adjust a spacing between the media edge guide and the side structure for accommodating different media widths. A guide adjustment assembly connected to the media edge guide for providing tool-free manual movement of a position of the media edge guide to adjust the spacing.

A printer includes a media path along which a media is movable, and a printhead assembly positioned along the media path at a first side of the media path, wherein the printhead assembly includes a printhead unit. A print roller is positioned along the media path at a second side of the media path such that media passes between the printhead assembly and the print roller. A biasing assembly is arranged for biasing the printhead unit toward the print roller, wherein the biasing assembly includes a biasing component that is movable in a direction across a width of the media path in order to laterally shift a zone of biasing pressure that urges the printhead unit toward the print roller as needed to accommodate media of different widths.

A printer includes a media path along which a media is movable, and a printhead assembly positioned along the media path at a first side of the media path, wherein the printhead assembly includes a carrier component and a printhead unit, wherein the printhead unit is slidably engageable with the carrier component to facilitate install and removal of the printhead unit in the printer. The printhead unit comprises a removal side that includes a gripping region, wherein the gripping region is defined by an upwardly extending recess on a bottom side of the printhead unit, wherein the upwardly extending recess is bounded on the removal side by a pull wall.

A device for providing a marking arranged or arrangeable in a circumferentially closed manner around a prolate object includes: a material interface for receiving a printed product output from a printer; a data interface for communicating with the printer for a providing or arranging of the marking as a communication; at least one actuator, using the printed product output from the printer, for arranging the marking on the object in a circumferentially closed manner or to provide the marking for circumferentially closed arrangement according to the communication with the printer via the data interface; and a memory readable by the printer via the data interface, the memory storing operational data of the providing or arranging.
