Ignoring white space when printing.

I have a series of images, each on it's own page like a book layout. I use a 13 x 19 canvas and place the images where I need to, along with text. Now, when I print, the printer assumes the entire 13 x 19 as printable, and the print head runs the entire sheet, including all the white space.

How can I get the printer to ignore the white space? Both my Epson and Canon run the same way so I would have to make a move on it in PS.

Lawrence,

Image -> Trim before printing.

If there is another way I don't know what it is. Photoshop Assumes the canvas size is the print size.

Use InDesign to do page layouts.

I think it also depnds upon the printer [driver]. Mine [Epson 1200] seems to skip over white [as it knows the paper is white, I guess.].
