QTR-Quadtone RIP

My interest in a 24" printer is because I have been told the paper transport is not by pinwheel and rubber rollers but by vacuum transport. It occurs to me that I never confirmed that. Anyone? Of not by vacuum, how does the paper move through the printer?

Thanks

The vacuum just holds the paper flat, the roller is what transports it, and yes, no pinwheels. You can control how much suction depending on paper thickness or curl. You can also control the platen gap.

OK, maybe I am asking the wrong question. The 3880 has rollers on top 
and bottom of the paper. Does the 7880 have rollers just on the bottom, 
or both?

The 7880 does have rollers but works by vacuum.

Both I believe because I had problems with roller marks when I did dtp.

Greg,

Just to clarify... you had roller marks using direct-to-plate with dry 
film polymer plates using the 7880?!!

Please say no!!
