HP's internal operating system intelligence in both my Spectre Laptop and Office Jet Pro 6978 guided me through the replacement of my HP Model 6830. I've been working in the computer industry for over forty years; this was the best end-user experience yet.
It was not clear before I purchased this printer that I cannot scan to computer creating a pdf. Now I have multiple steps to create a pdf of receipts for my business. Bummer!
I downgraded from an HP OfficeJet Pro 8600 Series All-in-One Printer, as the machine suddenly stopped working after many years of use. This HP OfficeJet Pro 6978 is portable, and does all the work of the 8600 Series, except for the Scanning to PDF feature, which this HP OfficeJet Pro 6978 does not support. You can only scan to picture mode (JPEG, PNG, TIFF). It's time consuming to scan documents individually to photo images, and then convert them to PDF. So I miss that feature from the 8600 Series, which just allows you to scan multiple pages during one scanning process to PDF.
If you are like me, and want that feature included in your scan to file or desk top, then this printer might not be for you.
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.
