An improved printer comprising a plurality of character rings provided with a plurality of characters on the respective peripheries thereof and corresponding pluralities of ratchet wheels and pawls. Each ratchet wheel is radially mounted on a character ring and a corresponding pawl is oscillatably mounted for engaging its corresponding ratchet at a preselected interval for stopping its associated character ring when a selected character is located at a predetermined position. Guides are provided...

A printer comprises a frame, a platen supported by the frame for undergoing rotation, and a printing head for printing on a recording medium fed between the platen and the printing head. The printing head is supported by the frame for undergoing pivotal movement into and out of pressure contact with the platen. A biasing member is mounted for movement between a first position in which the biasing member is in a neutral, unstretched state, and a second position in which the biasing member is in s...

A printer is disclosed and which includes a frame; a movable lifting member borne by the frame; a rotatable pressure drum borne by the frame; a rotatable fusing drum borne by the lifting member; a rotatable image drum borne by the frame and positioned in contact with the fusing drum; an articulation assembly pivotally borne by the frame and movable along a course of travel, the lifting arm engaging the articulation assembly, and wherein movement of the articulation assembly imparts movement to t...

A recording apparatus has a print head with an ink tank for supplying ink to the print head. The ink tank is carried together with a print head on a carriage, which is moved over a print medium so that the print head prints data on the print medium. The ink tank has an ink-empty sensor which outputs a first signal upon detecting that the ink in the ink tank has decreased to a lower limit. A controller causes the carriage to move to an ink-refilling position in response to the first signal. Then,...

A clamshell style printing apparatus for printing on print media, including linerless media, and a method for controlling a printing apparatus. The printing apparatus includes a main circuit board assembly located within a printer housing member that mounts relatively low speed electronic components, and which includes a dual-sided circuit board. A control board assembly is electronically coupled to the main board assembly via a SIMM connector and mounts relatively high speed electronic componen...

A printer is disclosed which comprises a type platen and a type head opposite the periphery of said type platen and spaced apart therefrom to form a given gap spacing therewith. The type head is located in a plane extending perpendicular to the axis of the type platen and is movable in a direction parallel to the axis of the platen. The typehead includes a plurality of impacting wires arranged radially about the axis of said type platen, a plurality of operating pins each secured to the rear end...

A time card printer comprising a plurality of type wheels rotatably mounted on a common supporting shaft and a plurality of printing rolls radially aligned with respective type wheels, the printing rolls being mounted on a common drive shaft which rotates in response to insertion of a time card and is parallel to the supporting shaft, each printing roll pressing the inserted time card against the type surface of the corresponding type wheel during rotation of the drive shaft, the printing rolls ...

A printer responds to channel commands including coded data received over a channel from a data processing unit by printing characters represented by the coded data using an electrophotographic printing arrangement. The coded data received by the printer is first translated into corresponding graphic codes or addresses by a translate table employing a predetermined translation code, following which the addresses are used to locate sets of character image bits stored within a plurality of charact...

There is provided a printer comprising: a fixed cutting edge; and a movable cutting edge that moves toward the fixed cutting edge over a predetermined cut moving range from a cut starting position to a cut ending position, thereby to cut paper in cooperation with the fixed cutting edge. In this printer, the fixed cutting edge can move between a fixed-cutting edge mount position at which it is possible to cut the paper in cooperation with the movable cutting edge and a fixed-cutting edge dismount...

A printer including a cover state detector and a paper detector. The cover state detector detects whether a cover is opened with respect to a casing of a printer, whereas the paper detector detects whether paper is present within the casing. When the cover is opened, a detection result of the cover state detector is transmitted to a print controller prior to the time when a detection result of the paper detector is transmitted to the print controller.
