Is it possible to revert back to a snapshot if upgrades to iPrint 4 patches fail?

I need to update a iprint printer profile, but it's still wants me to use IE which is nolonger working even with IE compatibility mode enabled in Edge.

We are still running iPrint 4 and I notice that there is 5 patches that needs to be updated. (Patch 9, Patch 10, Patch 11, Patch 12, Patch 13)

I'm never done any patches before, and I just need to make sure that if I can revert back to a snapshot, if the patch update fails.

Will upgrading to the latest patch on iPrint 4 fix my orginal issue of it needing IE to edit printer profile?

If not will updating tothe current iPrint fix the IE requirement issue.  What is the current iPrint version ?
