The CM2320 range of HP multifunction printers (CM2320fxi, CM2320nf) have the ability to send emails. They do, however, have one major limitation: they are unable to use SMTP authentication. In order to send emails from one of these printers, you will need an SMTP server that does not require authentication.
SMTP2Go provides an SMTP server that works with the HP CM2320 range as it does not require authentication.
Plans start at less than $2 per month, so can provide a highly cost-effective solution to your sending problem!
