I resolved this, will leave here for reference, and explain at bottom
Here's my setup:
iMac w/ El Capitain, UPS Worldship Admin
LAN-connected, WiFi off
Windows 10 in Fusion 7, VMware Tools Installed
UPS Worldship 10.0.22
Windows Firewall is OFF, both Public/Private
Running ESET EndPoint on Windows side, and ESET CyberSecurity on Mac side
iMac w/ El Capitain, UPS Worldship Remote
1 USB Zebra 2844 Printer connected to WINDOWS side in Fusion 7 via USB
This printer is Shared with all via Windows Printer Prefs
Printer is set as default in UPS WS settings
LAN-connected, WiFi off
Windows 10 in Fusion 7, VMware Tools Installed
UPS Worldship 10.0.22
Windows Firewall is OFF, both Public/Private
Running ESET EndPoint on Windows side, and ESET CyberSecurity on Mac side
===========================
Problem:
I can print labels from UPS WS Remote PC, but not from UPS WS Admin VM-PC
From Remote I can connect via Network to Admin VM-PC, no problemo.
I cannot find the shared printer to add it to the Admin printer list.
I cannot connect from Admin to Remote via ethernet Network.
My Windows setups are similar or same on each VM-PC, but I only get one-way networking.
Have now very temporarily disengaged ESET to no avail.
I have brought the Admin iMac/PC and placed next to Remote, connected to same switch.
=============================
Background:
I had the USB printer connected to the MAC side of the Remote Fusion PC, which was shared from MAC side and was available to Windows side....most of the time. It usually worked OK.
Eventually something would go wrong with this functionality, every few days, usually on my days off, and I would need to perform restarts on PC then MAC sides on each iMac to get the printer back on the Admin machine; this became unmanageable, so I tore that setup apart today and am stuck trying to go the more "simplistic" Windows-only route(should be).
I have moved our company entirely to Macs finally, and UPS is the last App for which we need Windows, then it will be Sayonara Windows. Until that happy day, I need to resolve this network/windows/Fusion issue.
======================
Side Question:
How do I look up the IP address or network device name of Printer on Remote VM-PC so I can try a Manual Add Printer process? I have no idea what the path would look like going through two layers of dirty Windows and two layers of Mac.
HELP please!
I'm running out of chicken-blood and holy water
Thanks!
=======================
Resolution;
I was apparently trying to connect over network to wrong PC address "WIN-XJFGHSD464JRYGJRIDfFHD" when I should have been trying "WIN-JFUDSYEHBfwef&#$JD"
Silly me.....I guess it was totally my fault.
