I inherited a color printer (with scanner) Epson Stylus TX210, with both its black and color ink empty. My question is, since I only print black and white document, will it be okay for the printer if I install only the black ink?
Epson printers are known for clogged nozzle. I wouldn't recommend printing in just B&W as the ink in the color nozzles will eventually dry and block the nozzles which are finer than human hair. Once this happens it's very hard to clear. If you want to print in just B&W buy a cheap Brother mono-laser printer. They are cheap to buy and super cheap to run on generic toners.
