Color ink cartridges cost noticeably more per page than black-only printing, and a document doesn't need to be visually colorful to end up printed in color by default — a report with a few colored headers or a chart can trigger a printer's full color cartridge for a page that's otherwise entirely text. Converting to grayscale before printing sidesteps that entirely.

Why This Matters Beyond Just Cost
Some printers also print noticeably faster in black-only mode than in color mode, since they're not cycling through multiple ink cartridges for a page that doesn't need color. For anything printed regularly — meeting notes, drafts, internal reports — converting to grayscale once before a print run adds up to real savings in both ink and time over dozens of print jobs.
