PrintDocument / Javascript

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello everyone!

I have a question about printing pdf files.

In an application the customer has to fill out a pdf form and print it.

The form contains some javascript routines. These are executed as soon as the document is printed. 
The javascript routines change the printed image: for example, a barcode is printed and OCR readability is increased by omitting grid lines.

Is my impression correct that the QPL routine "PrintDocument" can print the Pdf file, but without executing the previously mentioned Javascript routines?
This is only possible with the help of an installed Acrobat Reader (i.e. "ShellExecute") ? 

My system: Quick Pdf Library 18.11, Delphi 10.4.2 and Windows 10/11.

Kind regards
U. Blomeyer

	I've told it to you already but for the other ones here: QPL's PrintDocument converts the PDF to graphic format on the fly and outputs the resulting image to the printer. PrintDocument does not a real "open" with these PDF and due to this no Javascript code is executed.
