Abstract: A printing method includes printing an image on a sheet with a printhead, detecting an edge of the printed image in a widthwise direction of the sheet, and performing borderless printing, based on the detection result, to make a margin amount in the widthwise direction become not more than a predetermined value so as to prevent the image from being formed outside of the sheet in the widthwise direction.

Abstract: There is provided a printing apparatus having a supply function and a winding function, in which a sheet is guided to a desirable position. To achieve this, the apparatus includes: a supply unit configured to hold a plurality of rolls of a wound continuous sheet; a printing unit configured to print an image on a sheet drawn from one of the rolls held by the supply unit; a storage unit configured to store a sheet printed in the printing unit; and a guiding unit configured to guide a sheet discharged from the printing unit to the storage unit, wherein the guiding unit is capable of switching between guiding the sheet discharged from the printing unit to the storage unit and guiding the sheet discharged from the printing unit to the supply unit so that the sheet is wound.

Abstract: This invention has been made to cause a printing apparatus for conveying roll paper and performing printing to simultaneously attain a stable conveyance accuracy and prevent skewed conveyance independently of LF roller driving conditions and disturbance conditions that variously change as the roll paper state changes. For this purpose, a feed motor is used as a load generator for the roll paper. A section from a conveyance operation by the LF roller to the next conveyance operation is divided into a plurality of sub-sections. A feed mechanism is controlled by switching between a feeder load generation section and a feeder load zero section for each sub-section.

Abstract: There are provided a roll sheet conveying apparatus and a sheet conveying control method wherein it is possible to control motor driving for conveying a roll sheet at appropriate timing to keep constant the tension of the sheet to be conveyed without performing a special identifying operation. For this feature, a relationship between friction load torque on the roll sheet and the mass of the roll sheet is previously stored in a storing unit, whereby the moment of inertia of the roll sheet can be detected at appropriate timing during printing. As a result, the optimum tension of the sheet to be conveyed can be maintained by appropriately adjusting the driving control of a sheet feeding motor and a conveying motor without performing a special identifying operation.

Abstract: A conveyance apparatus includes a feeding unit, on which a roll sheet is settable, configured to feed the roll sheet, a conveyance roller configured to convey a sheet fed from the feeding unit, a first detection unit configured to detect a conveyance distance of the sheet conveyed by the conveyance roller, a second detection unit configured to detect a conveyance distance of the sheet drawn out from the roll sheet set on the feeding unit, a driving unit configured to synchronously drive the feeding unit when the sheet is conveyed by the conveyance roller, and a determination unit configured to determine a state of an end portion of the roll sheet based on detection results by the first detection unit and the second detection unit.
