Printhead Movement

The printhead moves by a direct-current stepper motor.
The printhead can print while moving in both directions (bidirectional print).
When the printhead is printing in both directions, it automatically finds the
shortest path to print the next line.
The maximum velocity of the printhead is 1117.6 mm (44 in.) per second for the
248x and 1041.4 mm (41 in.) per second for the 249x.

Vibration

Although this desktop printer is portable and durable, do not operate or place
the printer in vibration-prone areas. For best results, operate the printer on a
level surface.

Clearances

Printer operation produces natural convection, or airflow. To allow sufficient
airflow, make sure there is 50.8 mm (2 in.) of space around all exposed surfaces.
