Abstract
When a power supply mode is an AC power mode, if a correction value which is read out from a non-volatile memory is a second correction value α2 corresponding to a battery mode, a first correction value α1 is calculated according to an equation α1=α2×K2 using the second correction value α2, and bidirectional printing is performed by controlling an ejection timing of a print head based on the first correction value α1. Meanwhile, when a power supply mode is the battery mode, if the correction value is the first correction value α1 corresponding to the AC power mode, the second correction value α2 is calculated according to an equation α2=α1×K1 using the first correction value α1, and bidirectional printing is performed by controlling the ejection timing of the print head based on the second correction value α2.
