PrintBoss not working with Sage 300 CRE

Hi Everyone,

Since we updated Sage to v18.4, we also updated PrintBoss to v6.11.1 
(latest).

We are trying to email vendors by putting in an EFT run number. Crystal report has been designed to output this data.

When we select to print EFT Payment Notification to some PDF printer, we can see the output. However when PrintBoss 50 print queue is selected, Sage does not send any data to PrintBoss at all. Status says "Completed" but PrintBoss does not come up at all.

Is there anything in Sage 300 CRE that is incompatible with PrintBoss print driver ? 

Any logs I can check ?
