I bought a large supply of copy/print paper some years ago. Finally ran out of it and bought this. Weight and thickness specs nominally matched almost all other current copy/print papers. After opening it felt very thin to me could be my perception I thought and I had no good way to verify the specs. Immediately and frequently have problems printing text with my long time Epson P800 professional printer mostly dropping gobs of ink on the paper and often catching the paper leading edge upon starting to print. Can't remember that ever happening in the last ten years even with my predecessor EPSON PRO 3800 printer.
