Unless you are doing extreme precision professional work--likely an extremely small subset of the people reading this, if any--a calibration target from a black and white laser printer or a photo printer is fine and will give great results.
Some photographers seem to worship color correction in a weird way. Other error factors, like reflected light hitting your calibration target, are likely to supercede any minor color imprecision from those kinds of printers.
