Paul,
You can increase the memory available by using the 3GB Switch in XP.
When I booted up this morning I invoked the 3GB switch to check the difference it makes - I had the alternative boot.ini set up some time ago.
The result was up from 753MB to 1073MB so it would be worth a go for you and could solve the problem.
Maybe spooling to printer is lighter than building to Tiff.
Now that you've said that, I think there s a difference between Print to File and to Printer. Qimage sends data to a printer in "manageable" batches rather than dumping the whole lot to the driver. That would not happen with PTF I assume.
Yes, sure the file is not small, at 987MB, but why can Photoshop do it and not Qimage?
The other thing I've remembered is that PS has its own memory management system to overcome Windows limitations. However I believe that Qimage can
print much larger files than PS because it does not dump all the data on the driver at one go.
Terry.
