5) Set quadruple density graphics
(a) Code: ESC Z n1 n2 <graphics data>
(b) Compatibility: EPSON LQ/IBM
(c) Function:
• Upon receipt of this code the printer switches to quadruple density graphics (240
DPI Horizontal) for the number of columns specified by n1 and n2.
(d) Range:
• Range n1 = 0—255
• n1 in conjunction with n2 specifies the total number of dot columns to be printed
in graphics. Dots = n1 + (n2*256)
• Number of dots/line
(e) Additional details:
• The values for n1, n2 can be calculated as follows:
n = total number of dots to be printed.
• Quad-density graphics are printed in a Quasi-density, therefore, the printer does
not print consecutive dots in any one row.
(f) Related functions:
• This command is equivalent to the 8 pin graphic mode command specified by ESC*
"3" n1 n2.
6) Reassign alternate graphics codes
(a) Code: ESC ? m n
(b) Compatibility: EPSON LQ
(c) Function:
• Upon receipt of this command the printer reassigns one of the alternate graphics
modes or "m", so that it represents any other of the eleven graphics modes or "n".
(d) Range:
• "m" represents one of the following four graphics modes.
K Single-Density
L Low Speed Double Density
Y High Speed Double Density
Z Quadruple Density
