computer is not acknowledging printing requests-I cannot print

I tried using the printing trouble shooter multiple times and cannot figure

out why I cannot print. I have tried test pages, notepad, word, ecetera.

While attempting to print, I have watched the task bar for printing, it

appears for a moment that there is a job to print and then it disappears and

nothing prints. I am able to use my printer for copying and scanning. I use

windows XP and a Dell photo 924 printer.

Help please,

Sarah
