Why can't I get Blue Colors to Print Correctly??? It prints violet/blue!!

Question

I'm runing Windows 7 - 64 Bitwith Adobe CS5 Master Collection. But ever since I allowed CS5 Photoshop to control my new printer (HP Photosmart Prem C310) to do a test print of a graphic that I created all of my Blues print a violet/blue color, no matter what color blue I try to print. It has even affected MS Word & MS Project when I try to print known blue colored fonts or Gantt Chart Blues will no longer print blue. but it will print the same violet/blue color. I've even tried a brilliant stock windows blue which all view great, but prints the same shades of violet/blue! All my color paletes and blues view perfect. My monitor is calibrated and I've reset my new printer several times and still the same problem. I never had this problem before until I installed CS5 Suite.
A strange thing is that I can run the check printer test and the data and image that is stored in the printer willl print every color perfectly, including blues. Plus I've ran a full color copy directly from the scanner bed and the copy prints perfect as well. I almost feel as though Adobe CS5 has possessed my PC and Printer! So does anyone on here have the knowledge of getting this to print correctly like it did before installing CS5 Master Suite? Thanks to all who can take the time to respond back with solutions to my problem as I have been trying to correct it for nearly three weeks now! Could  the problem be in Adobes hidden files possibly??? Thanks....

Dave,
there are at least two explanations, why Blue appears Violet on a print:
1. The printer isn't correctly calibrated or not calibrated at all.
2. A difficult explanation, please look here at p.60,61:

(the doc may have 2MBytes)
We are in the color space CIELab. A printer color space (gamut volume)
looks like a fruit in CIELab.
Pure (saturated) blue is mostly out-of-gamut for the printer space -
it cannot be printed with correct appearance.
A gamut compression is required. The blue has to be shifted towards
the middle axis L* of CIELab, in order to make it less saturated.
Correctly that should be done on a curved line (p.60, plane a*,b*),
but often it's done on a straight line towards the middle axis (dashed).
This straight line crosses areas which are not blue but slightly violet!
Remedies:
Use Softproofing for the appearance in the simulated prints.
If it is photo, for instance a blue sky, then shift the sky blue slightly
towards cyan.
If it is a spot color or a strong RGB blue, then use something else.

Some illustrations are understandable without mathematics
(p.18-21).
Hope this helps a little.
