Z3100 short print limit?

[mcbroomf]

I just migrated to a Vista 64 machine, and I've just about finished installing everything.  I loaded the 64b driver and I've been setting up my paper length selections.  
I have a 24" Z3100, and now when I try to set up a print on 24" roll paper that is 24 wide and 16 long it says that it must be longer than wide.  It offers to "fix" this for me and makes a selection that is 8" wide by 24" long.  This certainly never happened on my XP Pro machine, I routinely print 16x24 using the full width and about 17" of paper.  All of my printing is done in Qimage.

Is there a way round this?

Thanks

Sorry, I put this in the wrong spot, can anyone delete it? I'll repost.
