QUICK SOLUTION. Had this same problem of needing to install the printer even though my printer printed fine for other docs. But I noticed that some CS4 files were able to print while others not. So I simply opened another few file, split screened the two docs, and simply copied the old layers to the new doc. During the process, I confirmed that the new doc showed printer properties window when promted to print. So wala! Problem solved! This will save you some serious time. : ) Just got an urge to share that Jesus loves you very much. Me too. : )
