Uh. Shops offering printing-as-a-service are one of the most common things found in every small town, all over the world. They're one of the first entrepreneurialist ventures to be developed in developing countries after electrification (just buy a printer and a computer, and charge $1 to print a page.) Every Internet cafe offers printing. Every parcel shipping store (UPS, FedEx, etc.) offers printing—and in fact many Internet cafes are just glorified print shops where you can pay to use the computers originally set up for printing. In villages of 500 people (such as the one I lived in as a teenager!), either the post office, the community center, or the elementary school (frequently all the same building) will own a printer, and allow people to pay to use it.
Okay, you might live in a cabin 200 miles away from the nearest town. 80% of people are not in that situation. 80% of people on this Earth have access to someone they can pay to print something for them.

Don't have to regularly print things in color. Most people don't. Unless you do photography for money, color very likely isn't a crucial part of anything you're required to be printing. (It might be a nice-to-have part of things you're required to be printing; or it might be a crucial part of things you don't really have to be printing; but it's unlikely for color to be crucial, and for the print to be required.)
I need to print things quite often, and yet I personally haven't needed to print anything in color... literally ever. (I did print things in color, when I used to own an inkjet, but in retrospect, I didn't need to have printed those things in color.)
