Only good for a short time.  Too blurry and smudgy for Barcode printing (Shipping labels / coupons)

This printer was OK for the first few months.  Then it habitually started refusing to print anything in the black ink.  I call Epson as it was still under warranty at the time and their solution was to try a new ink cartridge (and I only use genuine Epson) which they sent me free of charge.  That fixed the problem that time.

This problem had continued to reoccur.  To clear it I wind up doing MULTIPLE head cleanings (6-8) which wastes the color tanks and then I have to replace those as well.  As of today, all the head  cleanings I have done will not fix it so that this printer will print from the black tank.  I am done with it.  What a complete waste of money.

One other thing to mention.  If you are in need of a printer sharp enough to do bar codes, avoid this one.  Even on it's best day it was so smudgy and blurry, most bar codes I printed were not useable.

Not good. (Review is for all colors + black). They work, but print quality is horrible. Very washed out and uneven prints. Why bother with these?  Dell branded work great of course, as well as another brand found here (3 letters beginning with the 2nd vowel). Note: for either 3rd party brand, I do not enable the (non Dell toner) printer option.

Print quality is very good, but it only prints 3 to 4 pages at once before the quality progressively declines.  There is a long start up everytime you power on and whenever you send something to print, there is a lag before something prints.  If you ever cancel a print job mid-cycle, good luck getting it to reset so you can try printing again.

Very frustrating experience.  Will return ASAP.

I really thought I'd be good to go with all the great reviews, but I'm not happy at all. The images look pretty good on the print jobs, though not excellent, but black and white text is barely legible and all copies, color or black and white, have streaks and dashes down the sides. (Yes, I shook them prior to installing).

Our school district purchased these for general office printing. First of all, all 4 toner cartridges must be inserted and have "life left" in order to print! I.E. if the cyan is out, I am unable to print anything in black and white until a new cartridge arrives. Also, the manual feed for certificates, etc. is LOUSY. It sucks envelopes and cardstock in at an odd angle, which jams nearly all of the time. The manual tray is basically a joke. When printing slick certificates, it bleeds ink all over and curls them into little rolls as they come out of the machine. This was purchased brand new in Feb. of 2013, and has been serviced TWICE in less than 10 months. Keep looking!

-- Update:  This company may have had a bad batch, or they improved the quality (see original post below).  They contacted me and offered to replace the cartridges.  I received them and tried one, and it printed a very nice crisp page including graphics and text.  My original review post made it clear that poor quality happened after a number of pages printed, however, for now I am happy.  I hope the quality will stay consistent.

-- Original review --
Worked fine for about the 1st 50 pages.  Now it will not print graphic images.  They are quite smeared with absolutely no contrast or resolution.  Dont waste you money.  The cheap price is attractive, but it is a waste.

Disappointed with the engraving quality. Entire side Is double printed and letters are blurred into each other. Still legible but not what I was hoping for. Poorly done.

Pros:
1. Great price.
2. Good adhesion

Cons:
1. Crappy output.
2. Alignment is off a bit

 I was really hoping these inexpensive labels would print well but I was wrong. The genuine Dymo labels print very well -- as they should for the price. The black output is very dark and uniform while the text and graphics are crisp. When I print a batch of 50 labels, the area of the label that is printed on is very consistent.

 The OfficeSmart labels print like they would be a rejected batch from Dymo. The black output is not dark and there's an annoying, marble-like texture to the tone. The print area isn't consistent as it is on the Dymo labels. Some labels print higher, others lower, etc.

 For my purposes, I need a good quality print and the OfficeSmart labels fail in that category. If you just need to print out addresses and don't care about the quality of the print, then by all means stock up on these which is why I gave it 2 stars.

Labels were printed using a Dymo LabelWriter 400 Turbo

I knew I was taking a chance ordering low priced toner for my Brother HL-2340D laser printer, but thought I would take a chance after reading all of the positive reviews. I had nothing but problems. The pages were coming out with smears on the edges and blotches on the paper. It worked ok for a week or so, then I started getting error messages on my printer to move the tab on the drum cartridge back and forth. I did this, it would print out a few pages, then same message and no printing. I waited too long to return this item but wanted to make others aware of my dilemma. Bottom line, I'm probably going to end up buying another printer (and it will probably be a Samsung this time).  And I won't be ordering from this company again.

Digital programmer lasted less than a month and screen completely fogged over.  I would find another more reliable product to invest my money in if I had to do it over....

This product worked well enough initally but I was not at all impressed with it's true color abilties when used to print anything other then text. After a few months things only got worse when I began to notice severe ink smears or splotches appearing upon all printed documents. Now it's like it is possessed and it only works correctly after about 10 tries. Thanks to the crappy quality of this printer I will soon be purchasing a new one and without a doubt it will not be this model!

Bought these for my EPSON Work Force WF-7610. Ignored the warnings from the printer about using non-EPSON brand ink cartridges. These worked just fine at first, but after a few months of use, the print quality deteriorated rapidly. Now you can't even read any of the documents printed no matter how many times you clean the print head and perform the other maintenance for the printer. Looks like trying to save money on the ink ended up ruining my printer, because now I am getting the same terrible print quality even after replacing these LD cartridges with the expensive EPSON brand cartridges. Now I'm stuck with another $50 worth of LD cartridges that don't work, plus the new EPSON cartridge that doesn't work and I am going to have to replace my $250 printer. Ended up costing me more in the end by trying to save money on using aftermarket ink cartridges.

After the initial setup, which was a bit tricky, these printed ok for a short time.  But it wasn't long at all before a significant print degradation occurred, to the point that I pulled them out, tossed them and replaced them with genuine HP cartridges again.  In all, I don't think I was able to print more than 50 pages with these, and those were mostly typical black and white pages with a little color.  Overall, poor quality.

The quality of these generic labels is pretty bad. They don't stick well and the ink smears. Unfortunately, I use shipping labels to print stickers and labels for products (not just for mailing) so I can't use these for that. Now that I'm stuck with 200 of them, I'll have to use them strictly for shipping AND reinforce them with tape. I'm using Avery from now on.

I understand a fade out effect of printing but this is terrible. Its literally spotty in many places and none others. The spotting/printing is clustered and terribly done. I would NEVER but this again. The fabric is also VERY THIN.

Spend the 10 bucks more for better quality.

Cartridges weren't full when I received them and were used up within a month. Did not do a lot of graphics intensive printing. Only colored and black text- approximately 75 pages worth. In comparison to other generic/refurbished cartridges I've used in the past (which last on average for one year), these suck. Not worth the money for the little bit of printing you get from them.

ETA: The ones that sucked were from vivamart. I've ordered them from eforcity in the past and those lasted a long time.

I bought this at the end of October 2015 - installed it a few weeks ago. All the printing now comes out with ghosting (faint image of the print in the background - visible enough to be annoying). Tried to return it, but apparently you have to return it within 30 days from the date of receipt. Thanks a lot Amazon (NOT)
