The embodiments of the invention disclose a printer apparatus. The printer apparatus includes an apparatus body, a printer motion power device fixedly arranged in the apparatus body, and an information receiving and processing device fixedly arranged in the apparatus body. The printer motion power device includes first working chambers which are left-right symmetrically arranged in the apparatus main body. With the development of society, more and more printers appear on the market, but printing apparatuses for large area printing or printing for giant billboards are very few, and most printing apparatuses is slow in printing speed and low in clarity when performing large area printing operation. According to the invention, the printer apparatus is designed, which breaks a pattern that a conventional printer must be fixed at one point for printing and realizes high-precision and high-efficiency printing through novel design ideas. Therefore, the printer and a control method thereof ofthe invention are necessary.
