Can you see the difference between 16bit and 8bit printing?
Probably not,
the problem I was having was printing from PS CS4 using the HP driver I couldn't get the paper size figured out so It always wasted a lot of paper. If I had a lets say 12x18 document I want to print it landscape to save paper but it would always print it portrait. Thats why I used the web ap instead. Much easier to figure out the paper handling stuff for me. Maybe things have changed with the new driver.
I am just interested in what res to send to the printer as i mentioned in my OP.
On the Epson it was always 180 minimum, 240 regular and 360 for best quality.
I got these numbers fro Jeff Schewe
