Abstract:
1. A transfer control method of continuous paper in a printer including a tractor that is driven by a tractor driving source and has a sequential engagement portion which is engaged with engagement holes formed along a longitudinal direction of the continuous paper in which page dividing positions are set at regular intervals, and a paper feed roller that is driven by a roller driving source which is independent of the tractor driving source and is provided at a downstream side in a transfer direction of the tractor, the printer transferring the continuous paper using the paper feed roller and the tractor through a printing position of a printing head, the transfer control method comprising: controlling a transfer amount of the continuous paper based on a rotational amount detected by a roller feeding amount detecting unit which is disposed on the paper feed roller and detects the rotational amount of the paper feed roller, when each page of the continuous paper is printed; and when printing on each page is completed, performing a cueing process of transferring the continuous paper until a printing start position of a next page reaches the printing position; wherein the cueing process includes: transferring the continuous paper until the continuous paper reaches a reference transfer position at which a distance between the printing start position of the next page and the printing position is equal to a reference dimension based on the feeding amount of the tractor detected by a tractor feeding amount detecting unit for detecting a feeding amount of the tractor, the tractor feeding amount detecting unit being disposed on the tractor, and after the continuous paper reaches the reference transfer position, setting the transfer amount of the continuous paper with which the printing start position of the next page reaches the printing position from the reference transfer position as a target feeding amount.
