I use Photoshop CS2, I mainly use to print off graphics onto Hp Transparency Film, and I print with a Hp Deskjet 720C. I will select Hp Transparency Film for the Paper in Best print quality so there is a heavy print.
However, for some reason its not printing out in Best quality when I select this setup, its printing out a very light coating of Black ink, almost transparent.
My printer will print as normal on all other settings, have done something in the Photoshop settings? I have also tried putting in a new cartridge. Dpi is 300.
