lp/lpr can't print from cups client
I have cupsd configured on a remote host to publish its printers, and
the web interface on http://localhost:631 on the local server sees the
remote printers and a defined default printer. However:
lpq: error - no default destination available.
$ echo foo | lpr
lpr: Error - scheduler not responding!
And the following acts as a no-op:
$ echo foo | lp
This was working as-is a few upgrades ago. How can I troubleshoot this,
and what might be the problem?
