2001/10/02 Print double-speed double-density image EscYn n (27)(89)n1n2.... n1n2.... 12 • This command enables you to define and print a single line raster bit image on a single text line. • n and n define the number of bytes that comprise the image. 1 2 • The image consists of 256*n +n bytes of data, each byte representing a single vertical column of 21 4/30". • Each byte represents a vertical column of eight dots, the most significant bit representing the dot at the top. Simply set a bit to 1 if you want a dot to appear in that position, and to 0 if you want white space to appear. • Images are printed from left to right. • Images are printed at an approximate horizontal resolution of 120 dots per inch and at an approximate vertical resolution of 72 dots per inch. • You can only use this command in portrait orientation. • The printer always prints as fast as possible, hence this command is the exact equivalent of the Esc L command. 10 WIDTH "LPT1:",255 20 LPRINT "*** ESC Y n1 n2 ***" 30 FOR I=1 TO 5 40 '* DOUBLE-SPEED & DOUBLE-DENSITY BIT IMAGE MODE * 50 LPRINT CHR$(27);"Y";CHR$(160);CHR$(0); 60 FOR J=1 TO 8 70 FOR K=1 TO 20 80 N=2^J-1 90 LPRINT CHR$(N); 100 NEXT K 110 NEXT J 120 LPRINT 130 NEXT I:END ** ESC Y n1 n2 *** Sample 13 Print quadruple-density image EscZn n (27)(90)n1n2.... 12 n1n2.... • This command enables you to define and print a single line raster bit image on a single text line. • n and n define the number of bytes that comprise the image. 1 2 • The image consists of 256*n +n bytes of data, each byte representing a single vertical column of 21 4/30". • Each byte represents a vertical column of eight dots, the most significant bit representing the dot at the top.
