Claim 0:
1. A printing device comprising:
a substrate feed-out section which feeds out a web substrate;
a substrate transport section which transports the substrate fed out of the substrate feed-out section in a transport direction;
a storage which stores a width size of the substrate transported by the substrate transport section;
a skew correction section comprising a skew sensor which detects skew of the substrate, and adapted to correct the skew of the substrate with reference to an output of the skew sensor and the substrate width size stored in the storage;
an image recording section which performs an image recording operation on the substrate;
a first sensor which detects a width size-changed portion of the substrate upstream of the skew correction section with respect to the transport direction; and
a controller which, upon the detection of the width size-changed portion of the substrate by the first sensor, performs a skew correction stopping control operation to stop the substrate skew correction being performed by the skew correction section while causing the substrate transport section to continuously transport the substrate and, after determination that the width size-changed portion of the substrate reaches a reference position downstream of the skew correction section, cancels the skew correction stopping control operation, and performs a skew correction restarting control operation to cause the skew correction section to restart the substrate skew correction.
