Basic problem - an HP6L laserjet does not work when hooked up to a MacMini via USB adapter cable.
History - previously and currently a HP 4L laserjet used with a MacMini running OSX+. Worked fine on an earlier Imac running OS9 with special software. When cable switched to the MacMini from Imac, OSX immediately recognized the HP 4L and everything works great.
Desired change - Switch out 4L for nicer 6L.
Problem - 6L not recognized by the OSX. Have tried multiple plug configurations including via keyboard daisy USB chain and directly into USB port on MacMini. Have purchased a new adpater cable and still no go on the 6L. Switched cable back to the 4L and works fine.
Is there something unique about the 6L? I would think not as I never had any other probem with it, but you never know.
I am thinking there must be some particular oddity/personal misunderstanding of OSX configuration that is the problem here.
All help is appreciated.
