A printing device that may include a first print engine, a second print engine, and a web buffer device disposed between the first and second print engines to maintain an amount of web substrate therein, wherein the web buffer includes a first and second movable carriage, with at least one rotatable roller coupled to each of the two carriages and wherein the first and second movable carriages move synchronously away and toward each other to alter an amount of web present in the web buffer

An image printing apparatus and a method of controlling the same are capable of appropriately correcting the conveyance amount in each of a plurality of conveyance paths. In a case of conveying a print medium along a first conveyance path, a controller controls the driving of a conveyance motor based on first information. In a case of conveying the print medium along a second conveyance path, the controller controls the driving of the conveyance motor based on second information, which is different from the first information.

Automatic sheet feeding of an installed roll is performed more reliably. To this end, a leading end F of a sheet is detected on the basis of a change in an output value of a sensor while causing a roll R to rotate in a winding direction using the sensor capable of detecting a distance to the sheet separated from the roll R. After the detection, the roll R is caused to rotate in a feeding direction, and a feeding state of the sheet is determined on the basis of the change in the output value of the sensor.

A printing apparatus includes first and second supplying portions, a printer, and a winding unit. The first supplying portion can supply a recording medium on a conveyance route to the printer for first surface printing. The winding unit then rotates in a first direction to wind the printed recording medium. A wound recording medium edge is located at a specific location and then guided to a conveyance route opening portion if the wind direction is a second direction. After the edge is at the specific location, the recording medium is supplied through the opening portion to the printer for second surface printing. If the second supplying portion supplies the recording medium for first surface printing, then it supplies the medium for second surface printing. If a user sets a wound-in-advance recording medium to the second supplying portion, the second supplying portion supplies the set recording medium to the printer.

The invention provides a printing apparatus and a sheet storage device which meet a need for diversification in printing modes while reducing a load on a user. A printing apparatus includes a first holder which rotatably holds a roll sheet, a second holder which is located below the first holder and rotatably holds a roll sheet, a printing unit which performs printing on a sheet reeled out of the first holder or the second holder, a discharge port which is provided above the first holder and discharges the sheet printed by the printing unit, and a receiving unit which is provided between the first holder and the second holder and is capable of establishing a first state of receiving a front end portion of the sheet discharged from the discharge port and a second state of not receiving the front end portion.

A sheet feeding apparatus is provided which restrains a borne rolled sheet from being deflected to allow the sheet to be reliably fed. The sheet feeding apparatus includes a holder configured to hold the rolled sheet so as to be rotated; and a rotator configured to bear an outer periphery of the rolled sheet held by the holder from below in a direction of gravity, the rotator rotating with the rolled sheet while feeding.

The printing apparatus includes a supply section that supports a plurality of rolls into which roll-paper strips are wound and supplies the roll-paper strips, a transport section that applies respective transporting forces to the supplied roll-paper strips and transports the roll-paper strips, a printing section that performs printing onto the transported roll-paper strips, and a tension-imparting section that individually imparts respective tensile forces to a plurality of roll-paper strips against the transporting forces.

A first feeding unit is configured that is provided in a first printing unit that includes a first recording unit that executes a recording operation for a long strip-like recording medium pulled out from a first holding unit that holds the recording medium in a wound state. The first feeding unit further includes a pair of feeding rollers that sort the recording medium discharged from the first printing unit, to the side of a second printing unit stacked on the first printing unit or to the side opposite to that of the second printing unit. The first feeding unit temporarily accommodates the sorted recording medium and thereafter, feeds the recording medium to a guide path, and sorts the recording medium fed by the pair of feeding rollers, to the side of the second printing unit using a sorting part.
