IPC: B41J21/17
Filed: 1978-10-16
Abstract: PURPOSE: To minimize the shift time of the carriage for the pseudo operation of the horizontal tab by securing decision for the shift in the space or the shift in the back space through the data terminal unit and from the nearest tab position set up locally.  
     CONSTITUTION: When the data and the print control information are supplied to input buffer 1, process part 2 searches the horizontal tab code and shifts the print character data to output buffer 3 while renewing the present position register 4 so that it may indicate the print position of the data terminal unit. The print control information includes the remote/local tab positions, space/back space number, the line feed indication and others. When the horizontal tab code which has to be shifted to the remote tab position at and after the present position is detected, the operation frequency of the local tab and the space number required are obtained based on the information of control information part 5 and the contents of register  4. Thus whether the shift is given in the space or the back space is decided. In such  way, the shift time can be minimized for the print head carriage.
