Acrobat Pro hangs in flatting for printing
I hate the Acrobat Pro subscrption! It is not consistant with desktop version. It's slow to print, because it now has to flatten pdf. It is not user friendly.

I hear you! The Acrobat Pro subscription version can be frustrating, especially with how slow it gets when flattening PDFs for printing. One workaround is to manually flatten the PDF before printing:
Go to Print > Advanced > Check Print as Image (this can speed things up).
Or, use Preflight (under Print Production) to flatten transparencies before sending it to print.
I deal with print-ready files often at NYC Packaging Solution www.custompackagingnyc.com, where we handle high-quality retail boxes, food packaging, and custom labels. Making sure PDFs are properly flattened before printing is key to avoiding these issues. Hope this helps!
