A drive axle assembly includes first and second axleshafts connected to a pair of wheels and a drive mechanism operable to selectively couple a driven input shaft to one or both of the axleshafts. The extruded coil provides more strength and no weak points for coils, and thus a more stable, durable, airbed. The cut creates a curved surface with multiple asymmetries causing multiple imbalances within the blade. The print status acquisition unit acquires a print status of print data.
