you are looking for "Styles" and will need to change these in your template.
DIMENSION STYLE in this case...
BUT, also not that there is an option to print all colors as black as well, if you can get by with a BW print.
If you use the Solid Edge print dialog's "Print all colors as black", it forces all colors to black rather than grayscale thus not requiring you to change your colors... This is what @Johnson_BigMatt was referring to.
If you use your printer's Properties setting of Black & White, then it will print colors other than black as grayscale.
