Digital BW, The Print

Please help me before I shoot myself.

I'm running 
  QTR v2.1b
  QTR v2.1.5
  Win XP Home SP2
  Sharing is on 
  Name is Quad2200
  Loopback adapter on
  Printer port is USB
  Tif files appear to load into GUI OK

I am not getting anything out of the printer. The last line of the log
file reads
'unable to write raster data to driver!'

I have down loaded the latest Epson drivers. Uninstalled reinstalled.
Downloaded sp2 and installed, spent several hours talking with a nice
Microsoft tech support gentleman in India getting the printer sharing
functioning (service was turned off). I don't know what to try next.
Any help if GREATLY appreciated. I'm trying to print BW photos for
everyone this Christmas and the Epson metamerism is spoiling my good
work. Imageprint is only a last resort.

Thanks

Dave K
