Printing paper for an echo machine, especially when it's just black and white, doesn't require anything too fancy. Typically, you'd want a smooth, lightweight paper that can handle the printing process without causing jams or smudges. A standard copier paper, often referred to as "multipurpose" or "copy paper," should work well for this purpose. Look for something around 20-24 lb (75-90 g/m²) in weight. It's economical and readily available in most office supply stores. Just ensure it's compatible with your printer to avoid any issues.
