OOPS... once I loaded the right ICC profile for the scanner and the printer it all works very nicely now. Several orders of magnitude better!

Printer colors differ by small amounts from brand to brand of ink and even with same brand in different batches. Within Photoshop you can use the "replace color" to tweak a given (single) color. Regardless of how you do it, you have to sample printer output and match (tweak), to even to calibrate the printer using calibration standards. This gets you very close unless you have a super cheap scanner and printer and even with cheap hardware this allows you to accomplish the intended results.
