Had trouble with Export to IPF8400 Print Plugin. Latest driver (5.50), Plugin (6.0.2) and Photoshop (21.2.2). Everything would appear to work (artwork would preview fine, spool fine and bring up the Print Monitor), but nothing would appear at the printer.
• Export>IPF8400 Print Plugin
• Click "Set Configuration" on main window
• Turn off "Perform printing in the background"
• Set up printing, etc., as normal
The setting should be remembered from then on.
