Graphics Functions Eight-Pin Graphics Modes All 8-pin graphics functions require parameters, n1 and n2, which represent the length of the graphics string that follows the select graphics mode command, and are calculated using a temporary variable, n. • n = total number of graphics dots needed for the graphic string • n2 = integer of (n divided by 256) • n1 = remainder of the n2 calculation The simplest calculation, is to divide n (total number of dots needed for the graphics string) by 256. Then n2 is the quotient (the whole number) and n1 is the remainder. If you require less than 256 dots (columns), then n1 indicates the number of dots and n2 is set to zero. 6820 Series 80-Column Printer User Manual 69
