Thank you for replying; I appreciate it.
I used the software; it seems to me that I've installed everything correctly. I was given the cd that comes with it, chose the mac OS folder in which there was a driver, and all installations seem to go accordingly. I go to print as usual, and again, it 'acts' as though all is normal and it will print - it feeds a page, I hear the cartridges moving line by line... and out comes a blank page.
The one thing I have not seen is a 'test' page print - though it does offer checking if there are other issues, such as faded printing, or uneven printing, etc.
