Black mark detection

The black mark detection(POS Printer Supplier) technology is used to locate when printing the template printed bill. It can be understood as the starting or ending position of each document. The single black mark detection technology is widely used. Some Portable Printer China manufacturers use the double black mark detection technology. Compared with the single black mark detection technology, the double black mark detection technology has the advantage that it can realize the multi linked bill template printing. The so-called multi linked bill means that multiple documents of the same or similar type need to be printed each time, but the purpose of each document is different, so it is necessary to distinguish the starting printing position of these documents. The typical one is the traffic police ticket, which usually needs to print three copies, so it needs to use the double black mark detection technology.
