A flexibly adjustable color printer comprises a pigment system, a carriage system, a recording paper traction system and a printing base frame, wherein the printing base frame has a printing area in which recording paper is arranged; the recording paper traction system drives the recording paper to move; the carriage system is positioned above the recording paper; the pigment system conveys a colored tape to the carriage system; the pigment system and the carriage system can synchronously move in the same direction; the carriage system passes through the recording paper and remains printing marks on the recording paper; and the moving direction of the carriage system is perpendicular to that of the recording paper. As the recording paper is pulled by the recording paper traction system, the pigment system and the carriage system can synchronously move in the same direction, and the printing width and the printing length can be adjusted through cooperation between the pigment system and the carriage system, the printer can be suitable for printing recording paper with various specifications.
