A printerhas a media orientation detection meansthat detects displacement of a medium discharged from a media exit after media conveyance by the conveyance mechanismstops; and a media processing device control unitthat controls the automatic paper cutterto cut the media when the media orientation detection meansdetects displacement of the media, and permits processing the media by the processing unit after controlling the automatic paper cutter

Printing device and method with cutter actuated by displacement of media

A printerhas a processing unit that processes media; an automatic paper cutterthat cuts the media; a conveyance mechanismthat conveys media in the direction moving to an exit; a media orientation detection meansthat detects displacement of the media after conveyance by the conveyance mechanismstops; a limiting unit that restricts movement of the media toward the exit after conveyance by the conveyance mechanismstops; and a media processing device control unitthat controls cutting the media by the automatic paper cutterwhen the media orientation detection meansdetects displacement of the media.

A printerincludes a conveyance unit that conveys roll paper stored in a paper feed device; a computing unitthat calculates the distance between detection marks of the roll paper conveyed by the conveyance unit; a memory unitthat stores a first step count corresponding to the distance between detection marks; a communication interfacethat receives print data containing start coordinates for rendering image data of images to print in an image buffer; a print control unitthat corrects the start coordinates contained in the print data based on the distance between detection marks calculated by the computing unitand a distance between detection marks stored in the memory unit; and a print unit that prints based on the print data at start coordinates corrected by the print control unit

Printer, printing method, and printing system

After processing a medium B with a processing unit based on control data received from a host computerand stopping conveyance of the medium B, the media processing device control unitof a printerprohibits processing the medium B by the processing unit, waits until displacement of the medium B is detected by a media orientation detection means, and reports starting to wait to the host computer. When displacement of the medium B is detected by the media orientation detection meanswhile waiting, the media processing device control unitcuts the medium B with the automatic paper cutter, and then cancels prohibition of processing medium B by the processing unit.

A printer that receives requests to print on plural different media enables efficient system maintenance and system changes. A printer connected in a daisy chain to a host device or a first printer on one side and to a second printer on the other side has a communication unit that receives print request data from the host device or the first printer, and sends the print request data to the second printer; a print unit that interprets the received print request data and executes a printing control process based on the result of data interpretation; and a response unit that generates individual response data for the printer based on the result of the printing control process, generates unified response data from response data received from the second printer and the individual response data, and sends the unified response data to the host device or the first printer.

Printer and printer control method for daisy chain connection

A barcode printing method can easily and quickly find the location of a group of consecutive printing elements that can print a barcode correctly when the line print head has faulty printing elements. The printing device determines the shift range for the barcode printing position, aligns the center of the barcode print data with the center of the shift range, from this position alternately shifts the print data one printing element at a time left and right in the line direction, and finds a group of consecutive printing elements that can print the barcode correctly. A normal printing range can thus be found in a short time with the smallest shift compared with searching from the end of the shift range, and the overall efficiency of a barcode printing operation that executes repeatedly can be improved.
