Remove any images you may have on the invoice settings. I have the same issue and so far removing the images have removed the 505 and 404 errors
UPDATE still unable to print my invoices. I get a page that still states cannot find what you are looking for. crap… sorry
Remove images and check Test Mode. I can now at least print my invoices. Needs a fix or moving on from this one.
UPDATE: Had host change PHP mem to 256MB from 64MB, works out of test mode now.
I didn’t actually do anything and it’s fixed! Thanks!

If it is solved without doing anything, I wonder if it was a temporary downtime of your server. Do you have any hint about what happened?

The 505 error have nothing to do with our plugin. See: https://developer.mozilla.org/es/docs/Web/HTTP/Status/505
In your case, I recommend you to contact your hosting provider and report the issue with them directly.
