How do I fix getting "Changing “Media Type” to “Ultra Heavy 1” would cause an unresolvable conflict with the selected custom paper. No change will be made." when printing in InDesign after upgrading to Mountain Lion 10.8.2?
Sounds like a print driver issue, but my suspicion is that you may have specified a page size that cannot be combined with that weight media, at least inthe tray specified.
It would help to know the printer.
I have an Oki C9650. I can't print on any other type of media in any Adobe program.
You can try re-installing the printer, or check with OKI and see if there are better drivers.
Export a PDF and print that. Be aware, that AFAIK, CS4 is not fully supported under Mountain Lion and if this was an in place upgrade from an earlier O/S that will complicate things further.
Thank you for your help. I ended up going with Creative Cloud.
