Dc2 'Q' Release Optional Font Area - Seiko RP-F10 Series Technical Reference

For the font data of 1 character, vertical 8 dots are input as 1 byte data in the order shown in
the following figure. The following figure is the case of x = y = 20.
y = 20 dots
The calculating method of the memory usage m is different from the calculating method of the
total number of data bytes k, because the font image is stored by the low scan method when
registering in the memory.
The memory usage m is calculated by the formula below.
m = INT((x + 7) / 8) × y × (e - s + 1) + Number of bytes of memory control information
