Fix Tablet-POS Network Permissions

Printing from my ERP POS breaks down whenever the tablet tries to reach the network; the job never even reaches the printer. The connection itself seems fine, yet the tablet is hit with permission errors at the network layer. I suspect a mis-configured network permission that blocks the tablet’s traffic to the POS service.

Here’s what I need:
• Pinpoint why network-level permissions are refusing the tablet’s requests.
• Adjust the router, firewall, VLAN or Wi-Fi ACLs so the tablet can reach the ERP POS endpoint without drops.
• Validate that receipts print reliably from the tablet afterward.

You may use any packet-capture or remote-diagnostic tools you like—Wireshark, nmap, router logs, ERP POS diagnostics—so long as the result is clear: the tablet communicates and prints without permission errors. If you have experience with mixed Android-Windows POS environments or ERP network hardening, that’s a plus.

I’ll provide remote access to the ERP server, printer IP details, and the tablet’s current network profile. Once the fix is in place, I’ll run a live print test; success means no permission error and a completed receipt.
