The title of this post is wrong. It's not PrintSetup() but Print(true, true) already writing a PDF file (with 0 bytes and not valid):

Hi,

As you might have noticed, on https://community.appeon.com/index.php/qna/q-a/need-for-documentation-on-all-existing-pb-ini-entries there's a discussion about not being able to use the pb.ini setting without any problems:

[DataStore Behavior]
UseHwnd=No

The performance gain is significant, but as indicated by Benjamin Gaesslein, datastore.Print(true, true), will no longer show the PrintSetup where you normally could choose your preferred printer.

So he's got a workaround, which I'm trying to implement in the PFC 2021 classes. Basically you explicitly call PrintSetup() and then do a Print(false, false), when you were really trying to only do a Print(true, true). It works very well when you pick a 'normal' printer.

However, there's a slight problem if you choose a PDF printer. PrintSetup() and choosing MS PDF printer already PRINTS the datastore (not in a valid format) and then after that, when we call Print(false, false), you'll be prompted again for the output pdf filename. (this time that does result in a valid pdf).

Does anyone have an idea or suggestion to solve the situation? Could it be an Appeon bug with PrintSetup() in the first place?

Here's some video material of my tests:

Traditional situation: UseHwnd=Yes (or not in pb.ini) and no Benjamin-hack:

My current situation at the job: UseHwnd=No and no Benjamin-hack:

After applying Benjamin's Hack (UseHwnd=No):

To be honest, I think it's a bug of the PrintSetup() function in combination with MS' dialog, which should not show a dialog that prints when all you're asking for is to choose the print  device, but maybe that's due to the Microsoft PDF printer and not Appeon's PrintSetup().

[EDITED]
Hey, that's interesting! With CutePDFWriter, there's no problem at all!!!

NOTE: all the PrintSetup() should be read as "Print(true, true)". I made this mistake because in the PFC event pfc_print() we call of_PrintSetup(), and I assumed wrongly that it would call Printsetup() somewhere.

For anyone interested, I've drilled down to the problem of the "MS Print to PDF" asking twice for the output pdf file name. Not sure if it's anything that can be fixed by Appeon though: https://www.appeon.com/standardsupport/search/view?id=7763

Ok, I've pushed my changes to the pfc 2021 version on Github and created a Pull request. Let's see what Bruce has to say :)

https://github.com/OpenSourcePFCLibraries/2021/pull/3

I've also created a ticket for the help on printing datastores not being fully correct: https://www.appeon.com/standardsupport/search/view?id=7764
