Thats "ESPUL" to you pardner! No fooling, ESPUL and other 3rd party network
printing solutions support LPD/LPR for teh HP3000 and do not have the SNMP
limitation that the HP network printing solution requires. ESPUL can use the
native LPR daemon on the Linux box with no need to write any software. As the
commercial says: "call us, we can help".
