Are there specific network firewall settings that might be blocking printer communication and causing the 0x0000011b error?

Yes, firewalls on both the print server and the Windows 7 client could be blocking the necessary communication. Ensure that the firewall allows inbound and outbound traffic on the relevant ports (TCP 139, 445, UDP 137, 138 for SMB; or TCP 9100 if using a direct TCP/IP printing). Specifically check for rules blocking the print spooler service (spoolsv.exe).
