Hello,
you can do this with a separate PDF24 printer that saves automatically. Then PDF24 shows no window, and WinCC only has to print the report to this printer.
- Click ยป Settings at the bottom of the PDF24 Assistant and open PDF Printer. If WinCC runs under a different Windows account than yours (your screenshot shows a service account), click Run as administrator first, so the settings apply to all users.
- Click Install a PDF printer and add a printer, for example "PDF24 WinCC". Select it in the list.
- Under PDF Printer Tool choose Automatically save documents after printed.
- Under Auto Save set the Output Directory, e.g.
C:\Reports, and the Filename, e.g. WinCC %Y-%m-%d %H-%M-%S (date and time of printing). Leave Use a file name chooser before saving the file switched off, and switch off Show progress while saving if you don't want to see a progress window.
- Save the settings and select the new printer as the printer for your report in WinCC.
We recommend a separate printer instead of changing the default "PDF24" printer, because PDF24 itself also uses the default printer internally in some cases.
