Bought printer this few weeks ago and found it to be adequate for my needs. I use it mainly as a desktop printer for printing from PC, copying documents and scanning documents. Some comparisons are to my HP 4600 series that quit feeding paper and this is my replacement unit. Pros: prints quickly when it starts to print. Has a much better scan menu on the PC with fewer steps to accomplish the task. Larger paper holder that is enclosed and does not require a lot of attention. Cons, very noisy. Sometimes does not immediately print after releasing from the PC, this is annoying as it does not give a readily visible status. The automated ink replacement does not fit with my needs and appears to be more expensive than replacing as needed. HP should make this feature more affordable for the average user to help defer the cost of ink and gain acceptance. Things I am not aware at this time but need to see over time: Ink usage, I like the multi cartridge but i have no idea on how long the ink will last, the problem with all HP printers is the replacement cost of ink. Have not used the WiFi this will be a new adventure as I am not clear on how this works. Otherwise the printer works as designed, nothing special compared to other printers in the same class.
The original Pro 6978 purchased was replaced because it was defective. The replacement printer works well with one important exception. At least twice a week l have to use the Print and Scan Doctor to fix one both of these problems.
I bought this printer 3 weeks ago as a replacement of the exact same model. The OfficeJet Pro 6978 is a pretty good printer for the price I paid but I am disappointed with the reliability. My previous 6978 printer stopped working (the print head died) after 26 months of light use where as my much older Deskjet still working after 10 years. I would recommend the buy the 3 years care pack if you wanted to use it for at least 3 years.
Great for printing and faxing but not good for scanning documents. When scanning a document that is printed on both sides, the back side printing bleeds through to the front when scanned
Having used HP printers for years, when the previous model was exhibiting signs of aging, I turned to HP and this time went up a bit to the OfficeJet Pro. This is an excellent printer, so much faster, AND it connects to the wifi everytime without hesitation. (old printer did not) Our daughter is in college and she loves being able to print from her computer from anywhere in the house. Quality of print is great, and changing ink cartridges doesn't require a mechanical engineering degree.
