I am replacing an older Infoprint 32 laser printer I am replacing an old Infoprint 32 laser printer which is connected to a remote AS400 via TCP/IP. This printer worked fine for printing jobs and reports from the AS400, but it is getting a little long in the tooth. I am trying to setup a new Infoprint 1852 from Ricoh and am having some issues. We are using NAT to translate the printer's public IP to the printer's private IP. The remote AS400 has no restrictions on our firewall; all inbound and outbound connections are allowed. I have configured the new printer with the same private IP address as the old printer and have disconnected the old printer. From the remote AS400, I can ping the public IP, but when I send a print job to the new printer, I am getting the following message on the AS400:
Remote device rejected an attempt by the writer to open a connection.
1) An incorrect port number or internet address was specified in the printer device description.
2) The remote device, if it is a printer, may be busy printing from another host.
3) The remote device, if it is a printer, may not be ready to print and may require operator intervention.
Causes 2 and 3 aren't applicable as far as I can see; the printer is not busy and is ready to print. As for Cause 1, the public IP address is correct in the device description (and pingable) and the current port is set to 2501. I have tried changing the port to 5001 or 9600 as per some internet information, but that did no resolve the issue. Can anyone give me any ideas on how to solve this? Thank you!
