CAUSE:Gmail(R) requires SMTP over SSL. Most newer products will support SMTP over SSL; however, these particular models donot support SMTP using SSL encryption.

SOLUTION: You can use STunnel to allow non-SSL devices to connect. STunnel should be run on a computer on your network that is up 24/7. The network printers will connect to STunnel using non-SSL SMTP; then STunnel will bridge the connection to Google Apps(R) using an SSL connection. STunnel can be downloaded from: http://www.stunnel.org/Your stunnel.conf file should look like:

-- begin stunnel.conf --

cert = stunnel.pemsocket = l:TCP_NODELAY=1socket = r:TCP_NODELAY=1client = yes

[pop3s]accept = 110connect = pop.gmail.com:995

[imaps]accept = 143connect = imap.gmail.com:993

[ssmtp]accept = 25connect = smtp.gmail.com:465

-- end stunnel.conf --SPECIAL NOTE: Solution contribution by Stu Dern, ESS
