Digital BW, The Print

I'm not sure where the problem is but often I get a print half way 
through and I get the message that I have to restart my computer (G3 
w OS10.2.6)In other words a crash. What could be the problem? I have 
the Print Center Repair Utility and everything seems to check out OK. 
I still have 9.2.2 on the computer which I have to shift to if I do 
scanning with my Leaf45 (Reboot not Classic). I have photoshop 7 
loaded in both OS's.
