Rating: - Original HP cartridges are the only way to go - don't buy refurbished ones!
Like most of you out there, I think toner is too damned expensive. Recently, I ordered generic "refurbished" toner cartridges for my HP 3550 color laserjet. What a bad move. Color isn't consistent with non-HP cartridges and two of the four leaked toner powder all over the inside of my printer causing a total mess. Do yourself a favor and stick to brand new HP supplies for your HP printer. You'll be glad you did! Consistent output and high quality images don't happen by accident.
