I am trying to print any PDFs on PDF24 but the print assitant won't open. I am able to open it manually when I start the programm but the assitant won't open when I direty print the PDF. Is there any setting where I can disable to print assistant to pop up when trying to print?
Thank you for your reply. Unfortunately this seems not to be the issue because I get a print error on pdf printer itself. I am able to merge, compromise,.. PDFs when I start the assistant directly on the program but I am not able to print PDFs.
if a print job to the PDF24 printer ends with a print error, the Assistant cannot open, because the print job never reaches PDF24. Please check the following:
Update to the current version of PDF24 Creator.
The PDF24 Windows service must be running, it receives the print jobs. If it is not running, PDF24 shows a message with the button "Start PDF24 service".
Delete print jobs that are stuck in the queue of the PDF24 printer, they block the following jobs.
For the classic PDF printer: in the printer properties, tab "Ports", the port must be \\.\pipe\PDFPrint.
On Windows 11 24H2 and later, PDF24 may use the driverless PDF printer. Every print job to it fails if Windows forbids background apps for it. The installer of the next version allows this automatically. Until then, see the section "Background apps" here: https://creator.pdf24.org/manual/11/#63-classic-and-driverless-pdf-printers
If it still happens, so that we can reproduce this, please send us a screenshot of the error message with this button:
