Digital BW, The Print

I've installed the latest versions of QTR and QTRGui on my XPHome 
computer.  MS loopback adapter was installed and appears on the 
Device manager as an enabled network device.  My printer is a 4000 
and sharing enabled for Quad4000.  I have not been able to print the 
21 step tif after having selected it from the QTRGui Image menu.  
When I click on the Print button nothing happens.  There is no 
document in the 4000 print que.  I noticed that when I installed QTR 
there was no program icon to start QTR itself.  I'm really mystified.
