No output and no notification from the lp command

If you do not receive mail messages from the lp command when your print requests fail to print, you might not have had mail from lp forwarded to the login name you use while doing print service administration. Because, by default, lp sends all messages to the lp login name, you must arrange to have mail forwarded to the lp administration login before you start sending requests to the print service. Otherwise, you will not receive mail from lp when your requests fail.
