I have the same scanner.

What is the size of the jpg image that you have saved to print out. The 
scanner will produce files that can easily be over 100MB for a single image.

Using Kooka, I get a single A4 colour image at 300dpi to be 801KB.
As Richard suggested, under XSane, the same image at 300dpi gives a 1MB jpg 
file or a 25MB .pnm raw image file. I am assuming the difference is due to 
jpg compression setting. As saving the raw image from Gimp at 100 per cent 
quality gives a 5.8MB file.

If you save the image to disk, does it then take a long time to print and what 
are you using to print it?

Do all images on your disk take the same amount of time to print?

To print the 12KB file from Gimp took 24 seconds to a mono LaserJet 6MP.
The 1MB and the 25MB files also took the same amount of time. On a 8ppm 
printer.

Printing to a colour inkjet took almost a full minute on one and nearly three 
minutes on another.
This was done on a 512MB box.
