In /etc/cups/cupsd.conf change:
Code:
<Location />
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
</Location>
to:
Code:
<Location />
Order Deny,Allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.1
</Location>
where "192.168.1.1" is the IP address of the machine you're connecting from? And restart cups daemon. (Also see "Location /admin" and "Location /admin/conf"?)
