Intel Macs, Network Home Dirs and printing crashes

Hello folks, Here's a situation we are currently trying to correct. We currently have a number of G4 XServes running 10.4.7 Server PPC and a couple instances of Universal (AD bound/OD Master config). Our clients are largely PPC (eMacs and iBooks), but the Intel Macs (Ed iMacs and MacBooks) have been rolling in. Aside from some AFP service reliability/robustness issues, the PPC machines have been doing quite well with Network Home dirs. Unfortunately, we have not been able to replicate this success with the Intel Macs as of yet. Certain applications (MS Office apps, Inspiration8 for example) crash when the user atttemps to print. I initially thought this might be a Rosetta issue, but Inspiration 8 is a Uni app. The print job does reach the printer/prints, but we have had to train users to save the document first to avoid losing work ... not so good. Our techs have built printers manually, sent CUPS info. out via ARD, nothing seems to help with this situation. We do not have this issue utilizing Local Homes or Portable Homes (however, with Portable Homes we started to have issues with less than reliable MCX application .. e.g. Dock with Finder and Dashboard only). We most likely will be moving to Local Homes and trying to correct aforementioned issue with Portable Homes, but I would very much like to address the crashing apps/printing issue as well. Any thoughts at all? Thanks much! Curtis
