IBM Quietwriter III 5202 Manual page 80

Tab stop values which are not in ascending numerical order are
discarded. The zero value terminates the tab stop sequence.
ESC D followed by 0 will clear all tab stops. Tabs are set in every
eight columns beginning with column 9 when the printer is initial-
ized or an ESC R command is processed. For example, to set
horizontal tab stops in printer column positions 10, 20, and 40:
LPRINT CHR$(27) ; CHR$(68) ;CHR$(10) ;
CHR$(20) ;CHR$( 40) ;CHR$ (0) ;
ESC E Begin Horizontal Emphasized Printing
ESC
E changes
the printer to horizontal emphasized printing
mode. This mode is used to simulate the appearance of text
which is printed in emphasized mode on a wire matrix printer.
Text is emphasized by expanding each character slightly in the
horizontal direction within its assigned character position to give
it a bolder or darker appearance. Vertical and horizontal empha-
sized printing modes may be combined to enlarge the character
in both the vertical and horizontal direction. This gives the char-
acter an even bolder or darker appearance. Horizontal empha-
sized printing is ended by the ESC F (End Horizontal Emphasized
Printing) command or when the printer is initialized.
LPRINT CHR$(27) ;CHR$ (69) ;
ESC F End Horizontal Emphasized Printing
4-30
This command ends horizontal emphasized printing mode started
by the ESC E (Begin Horizontal Emphasized Printing) command.
LPRINT CHR$(27) ;CHR$(70) ;
