Generic PDF Printer Drivers and wwPdfPrinterDriver

The wwPdfPrinterDriver can be used with most PDF printer drivers that are installed into Windows. Windows 10+ and Window Server 2016 or later ship with the Microsoft Print to PDF driver which now provides a built-in PDF output solution.

This wwPDF implementation handles changing the printer, sending a report to the printer and waiting for the completed PDF file which is printed asynchronously to the printer spooler.

If you're using Windows 10 or Windows Server 2016 or later we recommend you use the Microsoft Print to PDF driver.

We've tested with a few other printer drivers - Nitro, FoxIt - and this driver works with both of them just fine. It should work with any driver that supports printing by redirecting the print spooler. One caveat is that the driver has to be able to run without UI prompts. Some older drivers cannot bypass the file selection dialogs and those will not work. However most newer drivers properly support passthrough file names that are sent as part of the print job.

Example

The following is an example that uses the Microsoft Print to PDF driver.

oPDF=CREATEOBJECT("wwPdfPrinterDriver")     

*** Specify the printer **name** from your Printer List
oPdf.cPrinterDriver = "Microsoft Print to PDF"

*** Optional - wait for doc to finish in milliseconds
oPdf.nMaxWaitTime = 10000

lcFile = SYS(2023) + "test.pdf"

IF !oPDF.PrintReport("custlist.frx",lcFile)
   ? oPDF.cErrorMsg
ENDIF

*** Desktop: Open the file and display it
* GoUrl(lcFile)

*** Web Connection Response Output:
*** Download the file from disk to Web clients
Response.DownloadFile(lcFile,;
                         "application/pdf",;
                         "CustomerReport.pdf")
