20150035883 | LIQUID EJECTING APPARATUS, AND CONTROL METHOD FOR LIQUID EJECTING APPARATUS - In a recording suspension period when a recording head is accelerated or decelerated in a non-recording region on a recording medium, or stops moving in the course of performing a printing process (printing job), a second driving signal is generated from a driving signal generation portion.
