Can the 0x0000011b error be caused by incorrect network configurations?

Yes, incorrect network configurations can contribute to the 0x0000011b error. Ensure that the Windows 7 machine can access the print server over the network, checking for firewall blocks or incorrect network settings (e.g., wrong workgroup/domain settings, incorrect IP addresses). Furthermore, ensure the print server and the Windows 7 machine are using compatible network protocols. Sometimes, disabling and re-enabling network discovery and file and printer sharing can help resolve the issue.
