Canon Photoshop Print plugin (IPF printers) fix for Mac Catalina

[graemem29257847]

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.

The fix:

• 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.

THANK YOU! I bought a new Mac and could never get it to print to our ipf8400 - this was a huge fix!

Many thanks! This worked for me too.

I printed three days ago, then suddenly today it didn't work....no changes as far as I know! I have no idea how the "Perform Printing in The Background" suddenly became checked!

I unchecked it and now printing again!
