I originally thought this problem pertained to my printer and or related software. However, after some experimentation I'm now thinking it is related to image editing which was done with GIMP.
In this case, I was editing a jpg file whose metadata did NOT include an ICC Profile. When GIMP opened the file there was no mention of any ICC Profile. The assigned color profile was the "GIMP built in sRGB" Profile which was no surprise. However, when I went to print the edited version of the picture on my Canon Pixma Pro 100 photo printer the result was drastically different (extremely pale in one case) from what was expected. I then went back and opened the saved .xcf file and performed an ICC profile conversion to a different profile that I normally use for the resulting image files from my photo editing. That file printed as expected.
Unlike this situation most of my photo editing pertains to raw files from my own cameras (Note: raw files get developed using other software before being processed by GIMP). This experience makes me think I need to gain a better understanding of the difference between Conversion and Assignment when it comes to color profiles. I have reviewed the GIMP User Manual but I'm afraid it is no help when trying to understand what is going on in the scenario described herein.
