The "ping" command reports that I can communicate with the PS-9000, but I cannot print.
Check the following to identify the cause of the problem.
[There may be another device assigned with the same IP address, which may be responding to the "ping " command] Check the IP address in "arp -a" command, after send to "ping" command. Check the IP address of the devices on your network. If you find the duplicate IP addresses, assign a different IP address to one of the devices.
After you send the "ping" command, issue the "arp -a" command, then, check the arp table to see if the target device has a proper combination of the IP address and Ethernet Address. If there is a duplicated IP address exists, in the "arp" table there will be an unmatched combination of the Ethernet address and associated IP addresses.
[Your printer driver on your PC may not be properly installed] Check if the printer driver is properly installed. If a printer port has not been assigned to the printer driver, set up the printer port using the Brother PS-9000 Utility.
[Check if there is any security software function such as firewall in the server or another network device] The security software function may be interrupting network communication with the product. Disable the function to see if the problem continues.
