HP 4250 manual Detected printer problem

●Check to make sure the printer is plugged in, is turned on, and is online.

●Check the status of network components in the print path. This includes whether components are in-service and powered up.

●Check the configuration of network components in the print path. This includes IP addresses and other settings. components include the PSA, the default gateway of the PSA, the printer, and network infrastructure (routers, switches, cables, and so forth.).

Cannot connect to printer-- connection refused by the printer (304)

Level: Critical Error

Category: Networking

Description: The printer was able to communicate with the PSA, but the printer refused to allow the PSA to connect to the LPD port (port 515). HP networked printers only allow 8 simultaneous LPD connections and refuse connection number 9. HP printers with many separate sources for LPD print jobs may generate this error.

Action: Verify that the IP address for the printer is for a printer (not some other device) (in the web interface under Print Services-->PrintShares-->Properties). Some older HP Jetdirect print server firmware (the network interface card for HP Printers) only allows one connection; you should upgrade the Jetdirect firmware card to the latest available version of firmware for the card.
