what brand of printer?

some have a program that will show you how much ink you have
and many have a utility section that you can run some print tests to clean the heads {nozzle}
If you go to your printers & fax section in control panel -then click on properties of your printer and look for utility.
If you find that explore there to se if there is tests you ca do.

You might also look your printer up online @ the brand website is best option first- {Epson, HP, Canon etc} and find the support/drivers pages- there might be new updates or such you can download.

I just found a update for my wireless card that i didn't know about.
