Thanks everyone for your replies.
I've disabled the border-less printing mode as Wiggy mentioned and that corrected the scaling problem. The images are now printing with their proper dimensions, however the edges are still truncated with ample printing space available, as you can see in the image below. I've tried both with "scale to fit" and without, which oddly enough seems to not make a difference in the actual printed output.
The image in the preview at this point is not trust worthy as the output is always different. I'm thinking this is potentially print driver related as I've tried various combinations that I would expect to change the print output such as custom margin sizes ranging from 0.1 - 0.25.
I've tried printing through Photoshop, Gimp, and Lightroom, all seem to favor an upscaled image when printing to the edge or truncates the image and favors a 0.25 margin size regardless if a smaller size is selected.
@quickfingers818, thanks for the suggestion on UnderCoverXP, I'll boot up my Windows laptop tonight and try that out. Maybe the printer drivers on Windows work better than on Apple OSX Mavericks ?
@wiggy, I will also give CS2 a try on Windows, after checking adobe.com I can see that the MAC CS2 was never built for old Power PC chipset and not the modern Intel CPU architecture that Apple uses today.
I'm sure that switching to legal 8x14 would sort this out, but I'd still like to have it work as its intended to. I'm going to try removing the entire print and driver environment from OSX and only re-installing the Pro-100 support. Perhaps OSX is getting confused by my previous print environment, which is disabled, but still installed... Any other suggestions would be greatly appreciated, I'd hate to have to resort to using Windows just to print...
