In an example of the disclosure, a web media is advanced through a printer during a printing operation, Tractor-feed holes in a tractor-feed lane of the web media are detected utilizing a sensor and counted as the web media advances. When the count of tractor-feed holes reaches a target tractor-feed hole n, a fiducial detection period is started wherein a sensor is utilized to detect a fiducial. A printing adjustment is determined based upon a time or time period that the fiducial is detected during the fiducial detection period.

A printing method and apparatus are disclosed, in which a printed document is separated from a continuous strip of paper by a cutting device having a movable blade that can adopt a rest position, in which the blade is retracted to leave free a passage for inserting the strip in a cutting zone, and at least one cutting position, in which the blade is advanced to obstruct the passage, with sensor means that is able to indicate when the blade is in the two positions.

A printing apparatus includes: a conveyor configured to convey a web print medium with holes arranged at a predetermined pitch in a conveyance direction; a printer configured to perform printing on the web print medium conveyed by the conveyor; a detector configured to detect the holes; and a controller. The controller is configured to drive the printer to start printing on the web print medium based on a timing at which a count value of the holes detected by the detector from start of conveyance of the web print medium by the conveyor reaches a setting value of a number of the holes located from the detector to a print start reference position on the web print medium at the start of conveyance of the web print medium by the conveyor.

A detection device is a detection device that detects opening and closing of a door with respect to a device main body, including a pressing member attached to the door, a sensor attached to the device main body, and configured to detect that the door is closed by detecting the pressing member, and a switch attached to the device main body, and configured to interrupt power supply when pressing by the pressing member is released, wherein the sensor and the switch are positioned above or below the pressing member in a state where the door is closed, and positioned so as to overlap each other when viewed from a vertical direction.

To provide a printing method capable of inhibiting a paper sheet from being damaged at the time of conveyance and efficiently starting reprinting with high positional accuracy after printing is once stopped. The present invention is directed to a printing method of printing a unit image G by a printing part 2 based on detection of a reference punched hole 41 of a hole detection sensor 4 to form a print portion P1, then stopping printing to form a non-print portion P0, then by a mark detection sensor 3 detecting a register mark G2, recognizing a boundary between the print portion P1 and the non-print portion P0, and reprinting the unit image G from the non-print portion P0 based on detection of the reference punched hole 41 by the hole detection sensor 4.
