My print bills are not attaching to our invoices via email send.  Very frustrating to go to the trouble to attach the item to the invoice only to have to reattach the item manually in the email.  Also when sending invoices in batch send the attachments do not send either.  I will set up 20 -30 invoices to send later and if any of them have attachments I have to send them individually because the attachment never sends in a bulk send situation.
