Abstract
A method for printing a reduced size of image according to a paper width by detecting a paper width, which is made up of the steps of detecting a maximum size of printing data after receiving a printing data from a host computer, and printing a reduced printing data in case of a size of the printing data being larger than the paper width. A reflective optical sensor is moved over the paper so that the reflected state of an emitted light by the paper is used for detecting the width.
Claims9
A method for printing an image according to a paper width, comprising the steps of:
- detecting the width of loaded paper to obtain paper data as to a width of said loaded paper;
- buffering printing data transferred from a host computer to provide buffered printing data;
- detecting a maximum width of said printing data from said buffered printing data;
- determining a reduction ratio by dividing said width of said loaded paper by said maximum width of said printing data if said maximum width of said printing data exceeds said width of said loaded paper so that said printing data can be printed entirely on one page of said loaded paper;
- converting said printing to reduced image data according to said reduction ratio if said maximum width of said printing data exceeds the width of said loaded paper;
- and
- printing said printing data, said printing data being printed as a reduced image if said printing data is converted to said reduced image data.
A printer for printing a data image according to a width of a sheet of paper, comprising:
- a controller operationally regulating overall operation of an image forming device through a prescribed control program with said controller receiving a maximum width of printing data for said data image and for converting said printing data to image data changed in size in dependence upon a determination of a ratio by dividing said width of said loaded paper by said maximum width of said printing data when said maximum width of said printing data fails to conform to said width of said paper, so that said printing accommodates formation of said data image entirely on the sheet of paper;
- a memory storing program data of a control operation of said controller and data produced during said control operation, said control operation determining whether said printing data is to be converted to said image data changed in size, and said control operation for printing said data image;
- an interface for interfacing input/output of data to said controller;
- a printing head for printing on said paper;
- a printing mechanism moving said printing head to print said data image on said paper under control of said controller through said interface;
- and
- a reflective optical sensor disposed to sense said width of said paper, wherein the data image to be printed is changed in size from an original image of said data image by said ratio.
A method for printing an image, comprising the steps of:
- providing a print media and an original document, said print media having a width, and said original document having a maximum width of printed data;
- determining the width of said print media;
- determining the maximum width of the printed data on said original document;
- determining a reduction ratio by dividing said width of said print media by said maximum width of said printed data on said original document if the maximum width of the printed data exceeds the width of said print media so that said printed data on said original document can be printed entirely on said print media;
- and
- printing an image for said original document on said print media, said image being a reduced size image according to said reduction ratio if the maximum width of the printed data exceeds the width of said print media.
