LPD uses LPR, I don't understand how they even get a job out using LPD.
It is what I expected.
Leaving the snmp community name at "mtasnmp" and all of the Mpc5503s Network Security settings like in the hardening cause it to not print with LPD.
Same settings and turn LPR back on and LPD prints right away which makes sense since LPD/LPR are used together.
I am still unsure if this is the real issue....
