Printer, printing method, and printing system

摘要

A printer 1 includes a conveyance unit that conveys roll paper stored in a paper feed device; a computing unit 100a that calculates the distance between detection marks of the roll paper conveyed by the conveyance unit; a memory unit 105 that stores a first step count corresponding to the distance between detection marks; a communication interface 106 that receives print data containing start coordinates for rendering image data of images to print in an image buffer; a print control unit 100b that corrects the start coordinates contained in the print data based on the distance between detection marks calculated by the computing unit 100a and a distance between detection marks stored in the memory unit 105; and a print unit that prints based on the print data at start coordinates corrected by the print control unit 100b.

主权项

1. A printer comprising:
a storage unit that stores a recording medium having first detection marks and second detection marks disposed at a specific interval; a conveyance unit that conveys the recording medium stored in the storage unit; a detection unit that detects the first detection marks and second detection marks of the recording medium conveyed by the conveyance unit; a computing unit that calculates the distance between detection marks based on the first detection marks and second detection marks detected by the detection unit; a memory unit that stores a predetermined distance between the first detection marks and second detection marks; a reception unit that receives print data including printing position information indicating a printing position; a print control unit that corrects the printing position information contained in the print data based on the distance between detection marks calculated by the computing unit and the distance stored in the memory unit; and a print unit that prints based on the corrected printing position information output by the print control unit.
