I've tried the gutenprint 5.1.3.U, but I get the same message ("GenericClass: waiting for device"). Upon reading the .pdf files included therewith, it appears that I need to install some sort of CUPS file first (!!??). (Will that install in the right place, graphically, just by clicking on INSTALL? Which version?). Then when I read about hpjis, I read about TWO other files that must be installed ahead of it! I don't know much about UNIX, root directories, administrators and such, much less command line compiling, etc. I just want to find something that will make my MacBook work with an HP Photosmart 1215 printer via the Mac's USB port. I've never had this kind of problem with a Mac or with an HP ink jet. What's happened to OS X in this iteration (10.4.10)?
