Question 1

How many ink cart. does it use?

Accepted Answer

All ink tanks are separate.  Four total.  Black, Cyan, Magenta, and Yellow.  They are large tanks that last much longer than your average photo printer ink tank.  For a look at the cartridges, pricing, and value I recommend a site such as  4inkjets or 123inkjets  (.com since I cannot link you there) They carry both official HP OEM cartridges as well as remanufactured.  I've had good luck with remanufactured cartridges from both these sites.

Question 2

What size is the copy screen, 8 1/2 or 8 x 14?

Accepted Answer

We've had this all-in-one for sometime now and are very happy with it. We do not fax but print and scan with it and it does a nice job.

Question 3

what is the maximum size of the print paper?

Accepted Answer

The HP Officejet Pro 8600 can print on legal size paper 8.5 in x 17 in.  It can print full bleed or edge to edge on the 8.5 in side.

It can scan up to 8.5 in x 11.7 in paper.

The HP Officejet Pro 8600 Plus model can print on legal paper and scan legal size paper.  It also has a much higher scan resolution than the non-Plus model.  Well worth the extra cost in most offices.

Question 5

What size is the display screen?

Accepted Answer

By "display screen" I assume you mean the actual display that shows status and where you can manually change setup and the like. If this is what your question is the GUI screen is 21/8" wide by 11/8" high, however the rest of the black screen area is used to enter your a phone number to send your fax, status of wireless access (on or Off where the LED is on when activated and off if disabled) In both cases the scree is touch enable and works perfectly.
Hope this answers your question but if you have more questions feel free to send me a line.

Question 6

Does it come with it's first set of ink cartridges? And how much are the ink Cartridges?

Accepted Answer

Yes, it does come with first set of cartridges.  Have not had to buy replacements yet but have been pricing them.  Online purchases seem to be less.  Can buy a black for $28 and the 3 colors run around $20 each.  This does not include shipping and handling but usually still proves to be cheaper than office stores or wal marts.
The higher capacity cartridges can run $40 for the black and $30 for colors.

Good luck.  I'm very happy with mine as a printer and scanner.  Don't do much faxing.   Really like being able to print from my Iphone.

Question 9

Is this printer compatible with Windows 8?

Accepted Answer

Yes this will work with Windows 8. You will have to download the new driver from hp, click 'support and drivers' and then type officejet 8600 in the box. Choose Windows 8 for your operating system and then download the full driver.

Question 10

Is this printer compatible with windows 8 and 8.1?

Accepted Answer

Yes it will. 
I don't think the driver disc that comes with it will have the drivers for Windows 8 or 8.1 or if they are the same drivers used for Windows 7.
I bought mine probably a year ago so 8.1 was not included on it.

In any event, just type HP Officejet Pro 8600 driver on Google or Bing and the first link should be the one you are looking for. Click it and scroll to 8 or 8.1 to select your operating system and you should be good to go.
