The maximum printable page length is 590.55 inches when using the Epson printer driver. Using a RIP may allow you to exceed this limit.
There is no limit (or very very large) using Qimage: you use the driver Banner Mode and the Qimage Poster feature to make very long prints that exceed the driver limit.
See Qimage Help, Learn By Example 6a.
If you set up your paging/swap file whatever, you will get it to print from Qimage OK
The criterion is as I described in reply #2; I don't believe the paging file has any influence on this, I can make my paging file huge but the numbers given from Qimage Help remain the same.
