I have an HP compaq nc6320 notebook xp windows, is it compatible with the printer Epsom R300?

Make sure you don't have installed Windows 8.1
There is some compatible issue like as you are facing now...!
your system will give you better performance on Windows 7

You can get drivers from HP official web site here

Good Luck and do rate if got help

download the win7 driver from the hp site for your model and download all of the the 7 drivers just to be safe from hp support

Hi,
It does not have any Windows 7 drivers on the HP page so some parts may not function. Windows 7 usually discovers and installs most of the drivers automatically however you cannot be quaranteed that everything will run smoothly.
You can check your system with the Windows 7 Upgrade Advisor.
Download it from here:
Windows 7 Upgrade Advisor

just remove the catridges and clean it and reinstall if still you facing problem replace the catridges.

Check device manager if you see any yellow icon or you may need to update drivers for your system....

go to the HP site (www.hp.com) and look for the support page, find the downloads for your laptop and get the bluetooth drivers you need there

i have a Compaq nc6320 when i plug in the power cord the electricity led doesn't want to turn on i have changed the cords and the adapters and i doesn't power on or even charge the battery, did any one have an idea what to do in this problem?

Hello,
it seems that its a not a problem with your hard disk at it load on to the windows succesfully. Chances are any one of these :-
1. Some one might have changed the user name or password.
2. The file that holds the password might be corrupted.
3.If you are using a network based login, ask your administrator for assistance.

The better solution is to Repair install or Re-Install the operating system...

Stephane, I ran into the same problem after wiping out my Compaq nc6320 and trying to install XP Pro. The fix is to disable SATA Native mode. To do this: Enter F10 Setup then System Configuration>Device Configurations>SATA Native Mode and disable it, save the changes and now you should be able to install XP Pro. Remember, when I did this the drive was blank, I don't know if that makes a difference or not. Best of luck! Bryan P.S. If you want to enable SATA native mode after you have installed XP Pro check out this link: http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=1042050&admit=-682735245+1161793137260+28353475
