I'm a home tutor to Korean kids and every week I need to ask the parents to print out study materials at home. I always text the parents through kakao by saying "한녕하세요~오늘 수업 재료를 프린트 좀 부탁드려요." I'm not sure if it's the right way to express it. DO I need the 좀 in this sentence?
Any more natural ways of asking in this situation? Just would like to make it polite but not too formal. Thank you!
