I installed 1.0.24 with the patch applied as per your instructions. This 
did correct the image scan at 1200 dpi for me.  Thank you for your 
assistance in this matter.  I only installed updated backends, is there 
a reason to install the updated frontends as well?

Now I just need to get Gutenprint upgraded to 5.2.8 from 5.2.6 so the 
unit is recognized as a printer as well.
