Thank you for your question, my name is ***** ***** I look forward to assisting you.

There is a driver available for it to work with windows 10, which was released last month and available herehttp://support.hp.com/us-en/drivers/selfservice/HP-Designjet-500-Printer-series/25301/model/1834668<
you said you tried downloading the driver from the internet? Is this the driver? Where you able to download it? What happened when you tried to install it?
I can see you are a first time user to the site. What we do here is either a question and answer type of conversation or remote support where I would actually connect to the computer and have a look and attempt to fix the problem for you.
Remote support can save a lot of time if you are not comfortable performing repairs yourself. Sometimes even with instructions you can make a mistake and make things worse.
I will send an offer through for remote support and should you accept I will connect and see what is going on and fix the issue. Otherwise we can continue to talk like this but I will need to ask a number of other questions and try and walk you through some steps.
Both options are 100% guaranteed by the way. Remote is just quicker and avoids the risk of you making a mistake and doing something wrong.
If you want remote click get extra help. If not simply reply to me.
