QTR-Quadtone RIP

I'm curious what the performance was like on the 720ppi file, as I found
that even a 360ppi 13x19 print brought print time to a crawl (this was as
2880dpi though). Not that that's necessarily a bad thing (wasn't somebody
asking how to slow the printer down the other day?), just wondering...
 
Also curious if the ppi of the source image really had any impact on the
banding issues you had (I've been testing this week and have been finding
some banding in certain images).

Thanks, guys. The 720 ppi image loaded and printed fine. 

You're right, Stephen; I did confuse ppi and dpi. The reason I 
boosted ppi to 720 is to get rid of the (slight) banding I was 
getting when printing 360 ppi files at 1440 dpi.
