Thanks Hyper, I'm doing 8 bit (B&W ;-)) at 1200dpi, hence the 32 Meg should be just right ... I suspect the Windows driver is doing something inefficient to cause the problems, think I'll have to find a way to test Turboprint at work before shelling out on my own laser (moot point as I havn't even got the next gen machine to run Turboprint on yet! My old A3000 would croak at the prospect of 1200 dpi).
