There is disclosed an ink jet printer for printing on both sides of a label web. The printer has selectively movable guides which enable the label web to be easily threaded through the printer and which enable the label web to be brought into an operating position for printing and advancing the label web. The printer has individually and selectively removably mounted ink jet print modules to facilitate changing of ink colors, replacing or servicing a malfunctioning print module, and so forth. The ink jet print heads of the modules can be individually selectively moved between printing and stored positions. The unwinding of the label web from the supply roll is facilitated by an unwind mechanism to prevent stretching of the label web. The system for delivering ink and recovering waste ink includes needles for penetrating a cartridge. A guard shields the needles when the module(s) are out of the printer.
