Cloud-based CRM that can easily print envelopes (single & mass)

Dear r/CRM community,

I have joined Reddit and your community as I'm looking for a simple CRM that must have one specific feature, namely the ability to easily print envelopes (single & mass). Ideally, I would be able to print a single envelope directly from a contact's page. Mass mailings should also be easy to print. The best CRM I could find so far is Daylite but unfortunately it requires a very recent OS version which my old computer isn't able to run anymore. That's why I was wondering if there may be alternatives.

Thank you very much for your help.
