Maximum printing speed is attained with the following conditions:
! When the driving voltage is 5 V, the character size is a 24-dot font, the line spacing is 16 dots, the temperature of
the head is 50°C or more, the number of simultaneously activated dots is 64 dots or less and the head division
driving is not performed.
! When the driving voltage is 7.2 V, the temperature of the head is 10°C or more, the number of simultaneously
activated dots is 64 dots or less and the head division driving is not performed.
! When the driving voltage is 8.5 V, the number of simultaneously activated dots is 64 dots or less and the head
division driving is not performed.
