Resizing for printing...

I have this image to print which I need to be 4X6 to fit in a frame.
I know how to do this with windows xp printing, this way is NICE using the wizard. You can even get 3 photos this size on a page. Unfortuneately, after all the work I performed on the image in PS6, its ultimately necessary to save it in .psd. Bummer! xp cant read and print .psd using the wizard.
I just want to forget converting the image to jpeg because of all the quality that is lost. So my only option is learning the photoshop printing tricks.
I want to print the image to a 4X6 without losing any quality. The image is now 1280 X 960 or 17.778 X 13.333. I can resize the width and height by replacing 17.778 with 6. But this makes the width automatically 4.5 which is one half inch TOO LARGE. I tried to use the automate: fit command but the image appears to lose its quality, although i know it hasnt lost resolution. Maybe its just how it appears on screen?
Lastly, once I can print the 4X6 using PS6, at that point I'd like to print 2 or 3 pictures on a page. (Like Win XP wizard)
If what I need can't be dome in PS6 let me know about any other program that is capable of taking a .psd file and printing it using templates exactly like xp does.

Thanks,

The answer.....

use .tif file format.

.jpg files have never been thought of as "good" prit graphics.

flatten the image, SAVE AS and THEN save the thing as a .tif fil....no quality loss, and importable into anythihng... also xp print wizard will print it.

I tried saving as a tiff and lost alot of quality and the file size went from 8 megs to 3 megs. THe picture is definitely different visually.

Please help
