No problem if you are a color shooter. Even photographers with their own color darkrooms often send out their film and reserve their darkrooms for printing. When you are on the road, almost anywhere you are, you can find a one-hour lab to process and print color negative. Truth is, I am a philistine. I think the computer and scanner, with their unique controls, already do a better job printing color images than the conventional lab.
Large printers are usually beyond the means of most photographers.
I don't think you need a darkroom if you double-shoot in color. However, none of this does you any good if you are a darkroomless double-shooter who prefers black and white. You can probably soup the film in your closet using a developer prepared from a liquid concentrate. I don't think many custom labs do a good job with black and white prints. I think the reason behind this is an economic one.
