A while ago, after years of working, eprint suddenly stopped for me and I got the command rejected message. I found it would work if I used gmail directly, but not from my domain. I spent a few very long and frustrating calls with HP support and got nothing resolved although they were having me start over on all sorts of stuff.
The problem for me, and I suspect for many others, is that a few years ago, HP changed it so that eprint will reject an email that fails a dkim check. Passing spf doesn't help - it must pass dkim. Without going into what exactly that means, you can check if your email has this problem by using dkimvalidator.com. It will give you an address to send an email to and then you can see if it passed or failed. If it passes, you have a different problem. But if it fails, you'll need to set up a working dkim record for your domain or have your hosting/email provider do it for you.
If you have this dkim problem, you may have other emails that won't get through as more and more email receivers are relying solely on dkim. After a long time of having eprint not working, fixing the dkim record made eprint work again for me.
Hope this helps someone!
