Hello,
sorry for the late answer. The classic PDF24 printers send their print jobs to the Windows service "PDF24" (printer port \\.\pipe\PDFPrint, for the fax printer \\.\pipe\FaxPrint). If this service is not running, the port does not exist, and printing fails with an error like this one. The PDF24 tray icon belongs to a different process, so the error appears even if the tray icon is visible.
Please check:
- Open the Windows services (
services.msc), find the service "PDF24" and start it. Its startup type should be "Automatic".
- Alternatively, start it in a command prompt opened as administrator with
net start pdf24.
- In the printer properties (Ports tab), the PDF24 printer should use the port
\\.\pipe\PDFPrint.

If the service does not start with error 1053, the fix will come with the next version.
