The strengths and weaknesses of the various general micro printer analysis _ printing equipment problems

Micro printer by printing machine, printing at least controller, power supply and the shell, and printing machine by the print head and word car motor motion mechanism, the paper feed mechanism as well as a variety of sensors, etc. The strengths and weaknesses of the various general micro printer analysis: 1. Cable miniature printer: compared with wireless micro printer, the higher the reliability of data transmission, but if use in mobile printing, will become very inconvenient. 2. Wireless micro printer: wireless micro printer now most are based on the IrDA infrared technique, but the IrDA protocols is complex, the accuracy of the data transmission cannot be guaranteed. 3. Pin type micro printer: pin type miniature printer is relatively common micro printer, domestic useful early print head ( Printing machine) Products. Needle is playing a good print documents can be preserved for a long time, of course, this requires the choose and buy of the ink on the ribbon must be good quality, so those used in a lot of convenience stores are injection, and because the pin type print head control is simple, cheaper panel solution can be used to produce, therefore cheaper. But needles and also has many disadvantages: large noise, slow speed of print, the print head loss fast, often need to change the ribbon. Because of its principle, these are insurmountable. 4. Thermal micro printer: thermal micro printer is also more common micro printer, than the pin type micro printer appear later. Thermal printers print speed, low noise, mechanical consumption is rare in the print head, and don't need the ribbon, dispense with the trouble that change the ribbon. But it also has disadvantages, because it is using a thermal paper, cannot be stored indefinitely, under the condition of closed light can save 1 - For five years.
