Mac OS 9 (SheepShaver) on MBP

After much trouble I have succeeded in getting SheepShaver working on my MBP. However I can't get printing to work. Also, I have found that creating HD images in SheepShaverGUI is the best way to get Disk Images which aren't easily corrupted. But I can't work out how to mount these disk images on the OSX desktop. Disk Utility (OSX) won't mount them. They are greyed out. The reason I need to mount them in OSX is to transfer OS9 applications to the HD which is the startup disk under OS9. If I copy such files from UNIX disk in SheepShaver, the OS9 apps are just documents not applications and can not be launched.

Any suggestions, including on the printing issue. I just want to print through my MBP connection which connects through Airport to a Xerox 7300 Laser Printer on my network. I have the appropriate Printer Description in the OS9 Sys/Extns/Printer Descriptions folder, exactly as in Classic on my Dual 2Gig G5.
