Purpose
Selects Quadruple Density Bit Image graphics of 240 dpi
horizontally and 72 dpi vertically.

Expression CHR$(27);“Z”;CHR$(
n1);CHR$(n2);“DATA”
Where:
n1 = 0 through 255
n2 = 0 through 31
n1 + (256 x n2) defines the number of data bytes to follow.
d1 d2...dk = ASCII characters for the dot pattern bytes.
n1 = 0 through 255
n2 = 0 through 31
n1 + (256 x n2) defines the number of data bytes to follow.
d1 d2...dk = ASCII characters for the dot pattern bytes.
NOTE:
d1 d2...dk (DATA) consists of 8-bit dot columns, with the MSB at the
top and “1” bits producing dots. (0 < =
top and “1” bits producing dots. (0 < =
d < = 255)
Comment
This mode is similar to ESC L, except that four dot columns are
printed in the space normally taken by two columns.
printed in the space normally taken by two columns.
Example
The following example produces quadruple density graphics of
the pattern used in the standard density example. The amount
of data must be quadrupled for quadruple density (the data is
used 108 times rather than 27).
