A friend of mine has a HP 6100 all in one that seems to have some issues with Tiger, it is shown as 'Inactive' under Print Set Up Utility, I have no access to his computer, but I guess he has installed the HP printer drivers 
Are the Mac OS X drivers enough?
Anybody with a working HP 6100 all in one under Tiger?
I have checked the HP site, I have found the drivers for the 6110 model but they are not Tiger ready, though
