I sized the canvas to 8.5 and 11. I layed the pic out and used 24pt type, but when I printed it, it came out tiny and looked like 1pt type.
What did I do wrong?
On the screen it might be that when using text the image is not zoomed to 100% and hence your text might look like big on screen but small when viewed at 100% of the image. Try viewing your image once at 100% and check if your font size is apporpriate. Else increase the font size and save and view in Photo Viewer or at 100% zoom in Editor and make sure it looks fine.
Also try to print on Adobe PDF prior to actual print out to make sure it works fine.
