If the glossy paper is a glossy LASER printer paper, then it can be printed in a laser printer. Laser printer paper comes in many different coatings: matte, lustre, glossy, etc.
Make sure that the glossy paper you have is designed for a laser printer. Not for an inkjet printer. If you print an glossy INKJET printer paper in a laser printer, it can cause the paper to burn as it wasn't designed to withstand the printer's laser heat.
