The printer is basically a Lexmark and uses Lexmark cartridges. Most places such as Staples will have a chart to show you which cartridges to use.

The drivers for this printer are readily available for free download.

Do this, make sure the the power cable is on directly to the wall outlet, then see if the screen says "powering up" ,problem solved. If it doesn't try opening up the thing and checking the connections to see if they are soldiered up and tight. If they are and still doesn't work, then buy a new printer, the thing probably got water inside and burned up. Also, if it does power up, but that's not the case here, try connecting to the computer ,getting the driver from compaq.com and updating the firmware, if that doesn't work I don't know anything else that will.

Download the software for your printer at the manufacturers website. Here is the link for your printers software : http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&cc=us&lang=en&dlc=en&product=216828&

Pick the version for which operating system you are using. Once you install the software you will have full control of your printer again and you can set how dark you want your copies.

I hope this is helpful to you, If it is please give me a good feedback.

Hi, As far as I can see there are not yet any drivers for your printer compatible with Vista on the Net yet but I have put a link where you can email Compaq for information.

Then I would try to reinstall my new printer.
