HP 45 Black cartridge did work but color cartridge 23 did not work or it did work los of red tint. Since I only print black color pages I was satisfied
more than  50%. Actually I was able to print  tax forms. Later I was trying to print color page and color photo, very poor quality with lots of red.

So far so good.  Absolutely no paper jams for the past year of use. Very good quality for black prints.  Color printing on the other hand, is very dull. Even the black comes out looking gray.

Positive:
* Quick and easy setup.  Software included does quick and simple scanning.
* Print time is decent for both color and black
* Very sturdy construction
* 4 separate print cartridges
* Printer cleans itself
* Auto feeder for copying multiple pages. (very useful while filing tax documents and making copies of it.)
* Also, has an open door option for manual feed scanning.

Negative:
* Black prints comes out looking dark gray. Not as rich as it should be.
* No USB cable provided (Like selling a car with no steering wheel)
* Printer uses INK to clean itself. 2-3 times a month. Even when the printer is OFF. ???
* Color photo prints on regular paper comes out dull.  Very dull.  haven't tried printing on photo paper yet.
* No envelope feed option on the paper tray.  Very confusing at first, but after 2 attempts, I eventually figured it out.
* No WIFI connection

I still gave it a 4 because the majority of prints I do are black and white prints.  (resumes, school work, labels, etc").  For Less than $100, you can't complain.  Replacement cartrdiges are also very affordable.

For Photo printing, LOOK ELSEWHERE!

UPDATE:
After using the inks until they were near empty, the colors seem to be more brighter for some reason and the blacks now looks black.  I guess it needs some breaking in time?

Also, Printer will warn you that the cartridge are empty and must be replaced, even though there is a good amount of ink left.  Enough for 30-50 more normal prints I would say. You can trick the printer into using it again just by removing the cartridge and reinserting them.

Looks like the printer is set to a certain amount of prints for each cartridge and just tells you to replace a cartridge after a certain amount of prints.  It doesn't actually know when the cartridges are empty. There is a small window on the cartridges to let you see how much ink is left.

UPDATE 7/27/10
After updating the firmware from the Brothers site, you can now continue to print in (black only) if a color cartridge is empty.  Before the update, if any of the color cartridges were empty, the printer would demand that you replace the color cartridge and would not allow you to print at all.  Not even in black.

----------------
UPDATE 2/25/2013
The prints seems to be blurry and very poor now.  Not sure if it's because I'm using 3rd party ink or because it's just getting old.  What also annoying is that the printer is slow to start.  Especially if you unplug it and plug it back in.  It will start to "clean itself"  So that fast copying or printing you need will end up taking 15 minutes.  Of course, you are only affected by this if you unplug the printer.

I'm now getting paper jam here and there. Looks like it's time for an upgrade.

The black is working just fine. The color is giving me some interesting results. I printed 10 copies of the same document and the "standard" colors of red, blue etc. seem fine but some of the, let's say, more interesting colors, shades of brown, gray and so on are giving inconsistent results. It would be one thing if they all came out the same (wrong) color but they are coming out different on each page. I have a 4700 series HP Printer. For the price it will do but won't buy the color cartridge again.

Black ink showed ink level on my printer screen, the colored did not. They both fit and both work well. Haven't had any problems yet with the color, it still prints great. For the price I don't mind at all that the printer is reading a low color level. I have already re-ordered the 2pk of 63XL black, since I mostly print in black. Great deal. I will continue to order my ink from JARBO. Very happy overall

I just started selling after my husband lost his job (we have to pay for our insurance) and I needed black ink for the Canon printer.
This is perfect being only black and not the useless rainbow of colors.
THANK YOU

I like the good, clear colors but am wondering why the cartridge runs low quicker than expected especially when I print mostly in black. Someone told me that when the black ink runs out, the primary colors of red, blue, and yellow in the color cartridge are mixed together (which equals black) and continues printing. I don't know if this is true, but to test this out, I printed a 10 page document in black. I already knew that my black cartridge was low because the indicator message would appear every time I printed something. After printing the document, which by the way came out fine, I looked at the color cartridge ink level and it went down very noticeably. If my arbitrary test case result is valid, then from now on I will replace my black ink cartridge soon after I get the 'running low' message so as not to waste the ink in the color cartridge which is an expensive way of continuing to print in black. However having said all of this, I will continue to purchase this product from Amazon because it is cheaper than stores in my area and with the bonus of no tax and free shipping I think its a bargain.

I ordered black cartridges and didn't have any problems, but when I installed the color cartridges in my printer they seemed to be 1/2 full.  I guess it's a good thing I don't print in color all the time.

I received this set of print ink cartridges promptly and so far, the black cartridge I loaded in was working just fine. The price is amazing and cost me less for 10 cartridges than I paid for one Lexmark cartridge the last time I purchased ink. Can't wait to try the color cartridges. I thought I have found my future ink supplier. When I reloaded the second black cartridge, my printer would not recognize it so I had to run out and buy ink  at full retail price since I was printing important documents so bye bye to the money I had saved. So far, the color cartridges continue to work well.

I print out a lot of shipping labels and use black ink twice as much as color ink. This package provides high quality ink for a decent price that lasts.

The black was not as dark as the cartridge that was replaced, but it prints great. 4 out the 5 due to the darkness of the print text

So far so good, quality of pics isn't crisp n sharp.  But, I don't print alot of pics mostly black n all went well. Just installed yesterday so I'll try n see the ratio of copies from Jarbo vs. HP .  Hoping for the best as the prices of ink is rediculous

This stuff is much darker than other black filaments I've used, and so far the print quality is excellent. I'm running 220c/65c, no issues at all yet.

I used only black ink so far and it lasted hardly for 30 pages. I ran out of black ink again. and the cartridge was a thin cartridge and not the big fat one.

It prints out just well. I feel like it prints just a tad lighter (like it's not that deep black color) but I'm satisfied for this price.

The black cartridge works great.  I haven't needed the color cartridges yet.

I just received my ink today and the black did not work either; however, after some troubleshooting, I was able to solve the problem. After the maintenance of cleaning heads and print test was not successful, I went to the control panel and changed the paper to glossy and believe it or not it worked.
