Comment 19 for bug 1840773

I pushed a fix for #3 and added a missing eg-string. I also confirmed that emails are working (at least locally, using sendmail and mutt) using the steps here: https://wiki.evergreen-ils.org/doku.php?id=dev:email.

I couldn't recreate #6, but I also don't have a receipt printer connected to the computer I was testing on. Perhaps there has been a fix elsewhere, or maybe this appears only when connected to a receipt printer.

Thanks for this awesome new interface, Bill! Hopefully we can get this into 3.12!
