QTR-Quadtone RIP

On the R2400 the nozzle check shows a pattern of short thin lines, and 
misalignment shows by one of the lines being out of position. I think 
some of the Epson printers have different nozzle check patterns that use 
small blocks rather than lines, than could mask this problem. Problems 
at the start and end of the page can also be a symptom of this (at least 
on the R2400), but can also have other causes. (I no longer use the 
2400, so this is from memory.)
(on Windows the QTR print process uses a much less complex printing 
pattern than the Windows print driver, so printing with QTR could show 
problems  while the Windows printer driver didn't)
