I check and it looks like the Staples basic Glossy photo paper is designed for use with inkjet printers. Photo paper designed for inkjet printers can prevent the toner powder from adhering to the surface properly.
HP makes glossy LASER PRINTER papers, though they are not as glossy as inkjet papers. A gloss inkjet paper is not compatible with an inkjet. Laser toner and inkjet ink bond to the paper in different ways.
