What program are you printing from?  If you can print the image from within an image editor of some sort, you should be able to specify the resolution to print at.  Usually it's specified in terms of dots-per-inch (DPI).  Typical resolutions are 75 DPI and 300 DPI, but others are certainly possible.  Certainly any program like Photoshop or The GIMP should allow you to specify the resolution when you print an image.  Figure out what the appropriate resolution is by printing a sample on a plain piece of paper, and then measuring the spacing between pads for which you know what it should be (e.g., IC pins are spaced on 0.1 inch centers).  If it's not right, make another guess, and try again.

When I shrink the PCB layout in Photoshop the traces  and solder pads gets realy pix´si not good

Have you tried specifying the print resolution as I suggested when printing from Photoshop?  That definitely should work, but may take some experimentation to find the proper resolution.

If you can't figure out how to do that, then you could try importing the image into a vector graphics program (e.g., Illustrator, Inkscape), setting up a 0.1 inch grid, and resizing the image until you get the right pin spacing. I'm not sure about Illustrator, but I know that Inkscape (which is free, so no excuses: http://inkscape.org/) will resize the raster image without loss of resolution.  As long as you have your canvas set to the right paper size, it should print exactly at the scale of the grid.
