I am running OSX 10.7.2 and Parallels7/Win7 on my iMac. I found that 64 bit Win7 is incompatible with my HP Color Laserjet 3600n, and HP tells me there is nothing I can do. So, I bought a new printer. Question: The folder for the HP 3600n is still in my Library folder, and I think this is confusing Parallels. Can I safely delete the HP 3600n folder in the Library without doing harm to anything else ?
