I have not used my HP LaserJet Pro 200 color printer in over a year because I have run out of black toner and have refused have to pay more for toner cartridges than I paid for the printer. Last time I bought a replacement I paid $100 for black and all three colors. When I found LxTek for less than $50 I figured that even if they weren't very good I wouldn't lose that much because the prices I found were over $300. I bought a bunch of colors and black, of course I don't use them for long, but so far there are no problems. I've been working in the printing industry for several years, so I'm very picky about print quality. I then bought this pack of four black cartridges and plan to use my printer for a very, very long time. CHECK OVER!
