1. When the ESC U 1 code is sent to the printer all subsequent lines are printed in unidirectional printing mode This mode is invoked by the super subscript mode and by the graphics mode Unidirectional printing is useful in printing tables and charts and ensures that columnar numbers and other characters are in alignment The ESC U 0 code is sent to the printer to cancel unidirectional printing and return to the faster standard bidirectional printing mode LPRINT Bidirectional printing FOR 1 TO 10 LPRINT 25 1 29 I NEXT LPRINT Unidirectional printing CHR 27 U CHR 1 FOR 1 TO 10 LPRINT 25 1 29 NEXT I LPRINT CHR 27 U CHR 0 The Function Codes COMMANDS USED TO CONTROL VERTICAL POSITION OF THE PRINT HEAD These commands are used to control or move the paper relative to the location of the print head Moving the paper up has the effect of moving the print head down the page Line Feed Controls PURPOSE Advance the paper by one line line feed command FORMAT LF CHR 10 REMARKS The line feed is set to 1 6 inch if DIP switch 1 5 is upon power up or printer reset If DIP switch 1 5 is off the line feed will be 1 8 inch The size of the line feed can be changed using the codes listed below When DIP switch 2 4 is a line feed is automatically generated when the printer receives CR code CHR 13
