QTR-Quadtone RIP

I purchased a 2880 for a number of reasons but a key reason was to use the single sheet feeder on fine art paper.  When I enter Quad2880 as the printer, there is only standard sizes. None of the entries about roll paper or manual feed.  Therefore the paper is not recognized as being in that slot.  Is there a work-around or something I can do to use the single sheet feed with my QTR and UC inks.  Or, what can I do to use my printer and fine art paper.  If it matters I use OS10.4 and QTR 2.6.2 and I prefer printing through Lightroom 1.4 but I could switch to PS if I need to.  Your info is very much appreciated. If I haven't explained it well then ask me a question so I can get back to printing.  Thanks, Gary
