The printing speed above is the value when the product prints with the standard print
density level at 24 V and 25C. However, the printing speed changes automatically
depending on the condition of the supply voltage or the head temperature.
The maximum printing speed above may not be achieved depending on the type of
interface, the setting of data transmission speed, and the combination of control
commands.
If the data transmission speed is slower than the maximum printing speed, the printing
speed may fluctuate and there may be some cases where the print result becomes
shaded and/or dot displacement in paper feeding occurs.
If the data transmission speed is much slower than the maximum printing speed,
intermittent printing will occur and white lines will be formed when printing graphics.
