What's the canvas size? 300dpi doesn't mean anything. A 300x300 px image set at 300dpi will print out a very nice image the size of a postage stamp using defaults. That's all dpi does is set the default scale. If the image is 300 pixels wide and you set the it to 300pdi that means it's going to print 300 pixels in one inch by deafult.

If you send the same imge to the printer and specify a physical dimension such as 5 inches by 5 inches using 300dpi the image would have to be scaled up because there isn't enough pixels. This will produce a soft and blurry image.

Confused yet? :P scale your image before sending it to the printer.
