Using an internal network, is it possible to print documents silently?

I have a client that hosts a touch screen kiosk in their lobby. It's essentially an internal html website. They want customers to be able to click a link and have a pdf print without seeing a print dialog or having to back track... completely unnoticeable printing.

I have read articles and tried snippets of code for almost a year without finding a reputable solution. There are those out 开发者_如何学Pythonthere that rightly warn of security breaches or that it cannot be done at all.

The client's old touch screen structure was made entirely in Flash which I am avoiding. BUT, they were able to pull this off. I am sure this question has been asked a thousand times, but is it really impossible?

The current CPU running the touch screen is Windows XP. They do have an IT guy that works close, but I am not sure what to ask. He never offered any other solutions.

Thank you

Not 100% sure what you're trying to accomplish but maybe you could trigger a server-side program to run instead of relying on the kiosk itself to handle the printing. You could configure the server to send these PDF requests straight to the printer.

Maybe you can bake a custom browser for them (using webkit for example) that prints without asking.

Chrome running in kisok mode, started with the --kiosk AND --kiosk-printing switches and with a default printer set, can print silently using javascript print().

This is Windows only AFAIK.
