The difference operated according to user, if main equipment is a side of active, main equipment reads own files, selected to need to send To the first file of slave unit.If slave unit is a side of active, main equipment has two ways to obtain the first file:Main equipment to Slave unit mailing list, slave unit according to inventory select the file to be transmitted, and send acquisition the first file data ask Main equipment is sought, main equipment receives the file data of acquisition first request from slave unit, searches and want according to the request of data The first file obtained, or main equipment receive the file data of acquisition first request from slave unit.If slave unit is actively A side, slave unit directly sends to main equipment and obtains the request of the first file data, and main equipment is according to obtaining the first file data The first file is searched in request.

Main equipment and slave unit are set up be connected after, display parameters of the main equipment reception from slave unit, if desired for by file Be sent to slave unit carry out it is shared read, then the first file got according to main equipment, according to display parameters by the first file The second file is converted to, wherein, the first file refers to that main equipment needs to send the file of slave unit to.

Wherein, the second file can include typesetting data and content-data.

Content-data can include literal code data and/or view data, and literal code data refer in the second file The code set of all text informations, view data refers to the set of image information, and view data can be strategically interspersed in In the coding of text information, or concentration is placed on after the coding of text information.Second file can only include text information File or the file for only including image information, can also be and both include text information, and the text comprising image information Part, the present invention is not limited.

Typesetting data can the paging information including file, branch's information, display font size information, times of image location information The combinations for one or more of anticipating, paging information refers to text information and image information is located at which page of file, such as 1- 100 words are located at page 1 of file, and the 101-200 word is located at page 2 of file, and by that analogy, branch's information refers to word Which of file information and image information are located at, and such as the 1-10 word is located at the 1st row of file, and the 11-20 word is located at text 2nd row of part, by that analogy, display font size information refer to show font size information used during file, such as 15*16,20*20,24* The dot matrix font size size such as 24,28*28,32*32, this font size size is the Pixel Dimensions of dot-matrix dot matrix image, picture position letter Breath refers to position of the image in content data file, and line number and columns shared by the view data.
