Apropos this, it also really helps to spend a bit more per page and opt for a smoother, higher-grade paper that can take toner more evenly. It is not necessary to splurge and use the finest grade of coated paper; simply spending 2¢ more per sheet and getting the next level up from the default paper grade was enough to make for a dramatic improvement.
I was hoping it might, and today I was pleased to learn it does. I’m finally getting the print quality and overall effect I envisioned on the trees booklet I am putting out.
It’s really no big surprise, as advances in paper quality (and the resulting image resolution) were one of the things modern serif fonts were designed to show off.
