A printing mechanism assembly, which includes a platen, a print head opposed to the platen for printing operation, a carriage carrying the print head thereon, and a guide rod for supporting the carriage so as to be movable along a print line, is supported on a plastic subframe. The subframe is provided integrally with channel-shaped reinforcing members extending parallel to the platen at front and rear end portions of the subframe. Each reinforcing member is formed integrally with a number of reinforcing ribs arranged at regular intervals in the longitudinal direction of the member. The subframe is mounted, at its front and rear end portions, on a main frame. For the mounting arrangement, engaging projections are formed on the rear end portion so that they can substantially horizontally engage mounting recesses in the main frame with the aid of vibration-proof rubber members. The front end portion of the subframe is vertically fixed on the main frame by means of fixing screws accompanied by vibration-proof rubber members.
