Accompanying drawing 2 is basic procedures of filling in print routine, after this program start, G, H, T, X, Y label each branch pointed will be changed over to, each branched program is finished its operation back return node R (except the exit function in the file operation, this operation will finish this and fill in printing), G, H, T, X, the different function of Y representative, wherein G is the scanning and printing operation, X is editing operation, Y is a correct operation, being the program that program of the present invention and other word processing programs have evident characteristic, is to realize important procedure of the present invention;

G in the G of accompanying drawing 3 and R and the accompanying drawing 2 and R same meaning, be two nodes in the whole procedure block diagram, in the printing that the G branch road points to, program says the word to printer earlier and makees 1/180 inch paper feed, confirm to start photoelectric scanner A sweep by serial port after paper feed is finished, then by interface circuit B this scan-data that reads back, and deliver to computing machine W through cable F, this data imaging is shown on the screen, at this moment finish a line scanning, program constantly makes printer make 1/180 inch paper feed, photoelectric scanner A constantly treats the scanning that fills up a document, and last is complete waits to fill up a document, and imaging is presented on the screen, with this image is background, and treating fills up a document fills in;

In the accompanying drawing 3 " judge whether and will print? " implication be: the LQ-1600K printer is 24 needle printers, it is that line space is printed 24 times with 1/180 inch that each printing one row of printer are equivalent to the single needle printer, meanwhile, the each stepping spacing of scan operation is 1/180 inch, whenever finish 24 scanning spacings of passing by and just in time print row, program will judge whether whether scanning the progression number of times after scanning is finished is 24 times, should print.

In the accompanying drawing 3 " judging whether to want printed contents? " whether implication: reaching also will analyze behind the progression number of times of scan operation has the content of filling in to print if being, if there is not print What, the printer inoperation, the scanning times counter reset is avoided the printer blank operation; Like this, if wait the fill substance that filled up a document, through printer port of printer, program can start printer prints automatically, otherwise printer is failure to actuate;

X in the accompanying drawing 6 and R are identical with X and R among Fig. 2, are two nodes in the whole procedure block diagram, and the program circuit shown in the editing operation of pointing at the X branch road is finished and filled in, inserts function;
