What stain remover product should i use for a microfiber sofa?

An upholstery cleaner with Oxy in it would probably take off the footprint, but ink pen--boy--that will bleed if you touch it with almost anything. You better consult a professional . Alcohol will remove ink--problem is on fabric it bleeds, so the stain gets larger but lighter. I wouldn't touch it with anything. If it weren't for th ink, I'd do the couch with a Rug Doctor.
