Problems solved by technology

Therefore, when the slippage is small, the correction unit of the conveyance amount is larger than the slippage, so it is difficult to correct correctly
Therefore, in this case, there will be a problem that the print quality will decrease
In particular, there is a problem that printed products that require high-precision printing, such as barcodes, cannot be printed with the required accuracy, resulting in poor reading of the printed barcodes.

Embodiment Construction

[0049] printing device

[0050] Embodiments to which the present invention is applied will be described below with reference to the drawings. figure 1 It is an explanatory diagram showing a schematic configuration of a main part of the thermal printer according to the embodiment of the present invention. The thermal printer 1 (printing device) is equipped with: a roll paper storage unit 2 for storing the roll paper that rolls the long recording paper P into a roll shape; The recording paper P ejected from the roll paper in the roll paper accommodating portion 2; and the thermal printhead 4 (print head) disposed at the printing position B on the conveying path A facing the heat generating portion are conveyed.

[0051] figure 2It is a plan view of the recording paper P. In this embodiment, long continuous paper is used as the recording paper P, and the surface of the recording paper P is provided with a thermosensitive color-developing layer. On the back of the recording p...

Abstract

The invention provides 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.

Description

technical field [0001] The present invention relates to a printing device and its control method, in particular to a printing device with a recording paper transport mechanism for transporting recording paper and its control method. Background technique [0002] Conventionally, a printer has been used that has a recording paper feed mechanism that feeds the recording paper by means of a so-called friction feed that rotates a feed roller pressed against the recording paper. Constructed to feed the length corresponding to the amount of rotation of the paper feed roller. In this type of printer, by performing the printing operation of the print head together with the conveying operation of the recording paper conveying mechanism, it is possible to form print character strings or print pixel rows at predetermined printing pitches in the conveying direction of the recording paper. [0003] In such a printer, the encoder detects the rotation of the paper feed roller, the rotation...
