mbutler,

For your camera's images at 72ppi the printout size would be very large and the quality very poor because they come out of the camera at 72ppi (much too low of a resolution for a good print).

I wrote something earlier to help someone else resize a photo for printing from their digital camera. Though the actual numbers will undoubtedly vary from your camera output, and perhaps you'd like to print at something other than 4x6, I think you can see the procedure and sustitute your values for the numbers in the following...BTW, as you increase resolution, the printed size goes down, they are inversely proportional.
----------------

Using your dimensions of 22x15" at 72 resolution from memory card, to resize to 4x6...

* make a duplicate of your image and close the original
* have the Layers Palette permanently visible on right side of workarea * double click the 'background' layer and accept offer to rename it Layer 0 * edit image as desired
* might be a good idea to save at this point
* with image still open...
* Go to Image Resize from Image on menu
* With Resample UNCHECKED, change only one variable, change the long side to 6" and let the other variables fill in
* image now 6 x 4.09" at 264 resolution
* Ok that
* when your dimensions are a little more than desired:
* get the rectangular marquee
* under Style, change to Fixed
* type in 4 and 6 respectively
* click on image, with cursor inside selection lines you can drag box around to include the portion which will comprise the image
* Image>Crop
* File>Save As>assign a name different than the original With my Epson this is how I print (I use Edit>Settings>No Color Mgmt)
* File>Print In Print Screen
* Source = Doc. Untagged RGB
* Print Space = Printer Color Management
* click on Setup On Page Setup Screen
* click on Properties On Properties Screen
Main Tab set to;
* media type>choose your printing paper
* mode>click radio button for Custom
* click Advanced On Advanced Screen
* print quality> photo 720 or photo 1440
* color mgnt>Color Controls
* Gamma>1.8
* UNcheck High Speed

I get very good results with this scheme. My monitor is calibrated with the Adobe Gamma Utility and the profile it created is loaded
