After a pdf is generated, to print, the user has to download and then open the pdf and print To download and I use the following code:

Response.DownloadFile(lcPdfFile,"application/pdf",[roster.pdf])

How can I send pdf straight to default printer without downloading and without user interaction.

Also, suppose I want it to print to a printer other than default, what's the code to ask for the output printer (like FoxPro's getprinter())?

Thanks for any help.

I already answered your question. It's not possible for security reasons. What if the PDF contained a virus, which is possible (and happens)? That's why the user who downloads the file has to print it.
