According to an embodiment of this invention, the following processing is performed to solve a problem of accurately determining an abnormal state in a carriage by using an acceleration sensor. Output values from a plurality of acceleration sensors mounted in locations which have low degrees of mechanical/physical coupling in a carriage and a printing apparatus main body are transformed into data in a frequency domain. Subsequently, a carriage operation abnormality and a level of the abnormal state are determined based on a plurality of acceleration values in the frequency domain and a comparison of magnitudes of the acceleration values.

There are provided a printing apparatus, a method for controlling the printing apparatus, and a storage medium. The printing apparatus includes a conveying unit that conveys a print medium; a print head that applies a color material on the print medium; an obtaining unit configured to obtain, in the case where a first surface of the print medium on which a first image is printed comes in contact with the conveying unit, information on a printing condition of the first surface that becomes a factor of changing a conveying speed of the print medium in the predetermined direction; and a control unit configured to control timing of applying a color material on a second surface of the print medium that is a surface at the opposite to the first surface according to the printing condition indicated by the information obtained by the obtaining unit.

A radio transmit-receive unit can perform the communication processing stably without being affected by high frequency noise with the system activation of a computer unit, whereby if a communication processing request from the radio transmit-receive unit occurs, the computer unit sets the system state of a sub-CPU being activated to a rest state, a counter starts clocking the signal receive time of the radio transmit-receive unit when the system state of the sub-CPU is in a rest state, and a latch circuit holds electric field strength information of carrier received by the radio transmit-receive unit upon the termination of clocking by the counter. And the computer unit switches the system state of the sub-CPU being at rest to an active state, based on the end state of clocking by the counter, to restart the activation of the computer unit.
