Embodiment Construction

[0021] Referring to the above-mentioned figures, there has been generally shown a printing device 1 which is particularly useful for printing tickets, bills, receipts, labels or other types of documents printed in real time.

[0022] In particular, the printing device 1 may comprise a cassette for containing printing paper or another type of printing carrier. The printing carrier usable in the above-mentioned printing device may especially be paper, such as thermal paper. In this patent document (specification and claims), "paper" or "printing paper" is defined as any type of print carrier suitable for printing (especially with a thermal print head), such as a ribbon (especially rolled into a Rolls, such as (thermal) paper rolls) of printable material, or a set of continuous fan-folded sheets (sheets), or a set of spaced sheets (made of paper or another printable material), or a Group of sheets of paper (such as labels) arranged in rows on a strip carrier.

Abstract

A printing device (1) is disclosed comprising a path for supplying thermal paper (P) unwound from a roll (3) to a thermal print head (7) arranged for printing on a first side of paper, wherein a linear image sensor (10) is arranged along the path, on a second side of paper opposite the first, transversely to an advancement direction of the paper, to detect the position of an alignment mark arranged on the paper.

Description

Background technique [0001] The invention relates to a printing device and a method of controlling the printing device, which are particularly suitable for printing on thermal paper unrolled from a paper roll. [0002] In particular, but not exclusively, the invention can be applied to real-time printing of tickets, bills, receipts and the like. [0003] In particular, the invention relates to a printing device manufactured according to the preamble of the first claim. Such devices are known, for example from patent publication EP1977900. [0004] A problem with known printing devices is to detect the position of registration marks arranged on the paper in order to control printing appropriately. For this purpose, it is known to use photocells arranged along the path of the alignment marks. However, the position of the alignment mark may vary according to the type of paper. Therefore, the position of the photocell can usually be adjusted manually or electrically to adapt t...
