How does it work?
Relative motion works in the following ways:
Intermittent mode:
When using Intermittent mode the printer must be fitted with an encoder to monitor the 
subtrate speed. A high resolution encoder is recommended.
Example:
•  The printer is set to print at a print speed of 300mm/sec.
•  The substrate travels in the same direction as the printhead carriage.
•  The normal speed of the substrate when in motion is 200mm/sec.
•  The substrate starts to move before the print is complete.
•  The SmartDate 5 then has to increase the print speed to match the new conditions 
(300 mm/sec + the substrate speed 200 mm/sec) 500 mm/sec.
The SmartDate X60 also has to accelerate the ribbon to match the substrate speed
in order to complete the print without compressing it.
Note: If the substrate is moving when a Print Go signal is received, a warning is
issued and no print occurs.
