Print handwriting besides italics?

[Skwerlmasta]

I've decided that I want to improve my handwriting. My girlfriend has the American Cursive book that she's going to work through, and I've downloaded the spencerian exercises from https://loopsandtails.com/spencerian/.
The only print (non-cursive) handwriting methods I've been able to find is italics, and I'm not so keen. I'll go the spencerian route if I must, but are there any methods for print penamanship to choose from?
I haven't really looked into calligraphy, is it possible to adapt some of the calligraphy scripts for use with a full flex fountain pen.
I searched the forums and didn't really find anything.

The Rosemary Sassoon book is a good starting point.
