If you have no experience with printing at home, why are you attempting to mentor a Pro-100 owner?
"Calibrating" one's monitor is how a photographer synchronizes (matches) brightness, hue, saturation, contrast and highlights, between digital viewing monitor and printed image. There is a HUGE difference between transmitted light color qualities (monitor) and reflected light color qualities (print). It is much easier to adjust the monitor than to adjust the printer.
Not only do I have extensive experience printing at home but I own the exact printer referred to in the OP. Calibrating the monitor cannot cure "muddy" prints. Perhaps you should gather the facts before making assumptions and sounding like an idiot and assh*le.
