Abstract
A printing device and a control method for a printing device enable eliminating paper feed error due to slipping between a paper feed roller and recording paper when printing. The control unit of a thermal printer has a slippage calculator that runs a process to calculate slippage between the recording paper and platen roller when conveying the recording paper during printing, and a conveyance distance correction unit that runs a process to correct the paper feed distance of the recording paper when printing to each printing area based on the slippage that was just calculated. The conveyance distance correction unit runs a process that inserts a non-printing area d of a length corresponding to the slippage to one or plural specific positions in the original print image.
