Cool TonerCompatible Toner Cartridge Replacement for HP 42A Q5942A 42X Q5942X Q1338A for HP 4250 4200 4350 4300 4250N 4240 4350N 4250TN 4250DTN 4350DTN 4350TN Printer Ink (Black, 1-Pack)

This Toner cartridge slipped perfectly into my HP4250. I am so appalled over the ink scam being perpetrated by the home office printer manufacturers that I threw my ink guzzling color printer into the closet and purchased a refurbished LaserJet 4250 for $90. For the same cost as a black ink cartridge, this toner cartridge will print 20.000 pages compared to 770 pages from your standard office jet or inkjet black printer cartridge. AND.. it prints 1.3 pages per second! Also, as you are probably aware, your office jet or inkjet printer will cease to print ANYTHING if ANY ink cartridge runs dry. Well.. I had enough of that crap. I mean, its a $102 for a full set of color ink cartridges, and the most you can expect is 770 pages? I just got tired of feeling like a sucker every time I needed to buy ink. Color be damned. Who needs it.

I've been burned in the past with non-HP cartridges. The print quality can be iffy. Some of them leaked. Not pretty. When the time came to replace the cartridge in my trusty LaserJet 4200, I balked at the $200 cost for genuine HP (even on Amazon). I decided to take the chance and order the Cool Toner equivalent for $30. It arrived right on schedule in excellent packaging with instructions and return slip. I installed the cartridge and powered up the LaserJet. No hassles and no squawks from the printer. Print quality is excellent and clean--no lines or spots. The LaserJet firmware thinks the cartridge is from 2011, but I kind of expect that from non-name-brand cartridges, and it doesn't affect anything operationally.By the way, it turns out that the old cartridge was also non-OEM and was identical to this new one down to the model numbering label. I had installed it about 4 years ago and got about 300K pages out of it before it ran out of toner.Bottom line: hard to beat a $30 laser cartridge that works and doesn't bleed toner all over the place.

I’ve ordered 2 toner cartridges from this company and the first one worked perfectly with no issues. My printer read it as an original and used it for almost a year. I ordered a 2nd one and worked great for a few months, and somehow started to print with a dark strip on the side (must have been a fluke). I called the company right away and they tried to help me resolve the problem or they would issue a refund. Unfortunately it didn’t fix thee issue and they were kind enough to issue a refund. I will gladly continue to purchase from them in the future!!

Rated at "10,000" pages which is, of course, an estimate. I used it print the same materials (exactly) that I printed with cartridges from another vendor. With the cartridges from the other vendor I printed about 6500 pages,(multiple copies of a 500 page document) before they started to fade. Consistent capacity from each cartridge.This cartridge printed not quite 2000 pages (around 1850) pages and went dry. I shook it, did all the normal things you do and it was still printing just fading gray.Won't ever buy this brand again. Not just a waste of money but the Per Page cost ends up being MORE expensive than a $200 HP cartridge.

I only use a couple of these cartridges a year, printing papers for my classroom. With the cost of remanufactured cartridges, printing in my room is cost effective. I've tried several cartridges over the years. This one seems to be producing a similar number of pages to the OEM one. My printer is an older, bottom of the line laser for that model range. Some of the 42 cartridges won't work, because of that,I'm always careful about what I order. This cartridge worked like a charm, quality is good!

The toner cartridge worked fine for several months, but then started producing black blobs every 1.5 inches or so along one side of the page. It also would faintly reproduce parts of the document below the intended location, like an image artifact shifted down the page. Save your money and buy a better quality cartridge.11/25/20 - Just to follow up, I removed the toner cartridge from my home printer and took it to work to test on my work printer. Same result - very bad artifacts and blobs/streaking down the page. Clearly the toner cartridge is bad. Waste of money!

I was skeptical of buying a non-HP toner cartridge for my LaserJet 4250 since I have had bad experiences with generic toners for it in the past. But I must say this Cool Toner has better packaging, my printer identifies it as a genuine HP cartridge, there is no toner leakage, no streak marks, and the output results appear better and darker than with the HP brand! I love it! I was so tired of paying well over $200.00 for the HP cartridges and am so pleased that I discovered such a great alternative that I can trust

EVERY CARTRIDGE WE BOUGHT FROM THIS COMPANY HAD TO BE RETURNED FOR A REPLACEMENT, AND NOW THE ONE THAT WAS LEFT OVER IS OUT OF WARRANTY BY 2 DAYS PLUS AFTER INSTALLING IT, IT SH0WS WE ONLY HAVE 1000 COPIES LEFT BEFORE IT IS EMPTY!! THE FIRST CARTRIDGE WE TRIED TO INSTALL BLEW UP ALL OVER THE PLACE. VERY DISAPPOINTED!!

Acceptable quality but would not really recommend. The ink is much lighter than genuine toner cartridges (or indeed other compatible cartridges that I have bought in the past). You can read the printed documents, but would not be good if you needed a high quality print for professional presentation (letters, accounts, reports, etc).

Have had problems in the past when using "compatible" cartridges but this one worked perfectly from the start. Very happy with the print quality and price.

I purchased a set of these timers and I must say they are as good as the Brother originals. They print well, they last long and are much more affordable, 5 stars all round

Not compatible with brother MFC-L2750DW despite saying so in description. Contacted the seller who advised return for a refund.May work with other printers, I cant say.

Great product no problems
