Excel for Mac: save sheet as pdf disables printer communication?

Hi all!
I have a workbook that saves sheets as pdf and send them to the printer.

Problem is that once a sheet is saved as pdf no sheets are sent to the printer until the workbook is closed and reopened again.
Looks like saving as pdf disables printer communications.

The issue occurs only on Mac (Macintosh (Intel) Version 10.15.4 (Build 19E287) and works fine on Windows.
Extra problem for me is that I don't have a Mac. Searching the web for this problem delivered no results.

The actual workbook having the problem is too big and complex to post here, but I'm attaching a small demo workbook which shows the same issue.
The demo opens with a userform having one button.
When the button is clicked the sheet is sent to the printer and then saved as pdf.
The first time the button is clicked the sheet is printed and saved, but all following times it's clicked nothing is sent to the printer.

Hope there's someone outthere having a Mac and recognizes this issue or can point me in a direction how to solve this.
