If you want a perl equivalent of the Javascript snippet above that prints a web page to the client's printer, no, there is no function or module in perl that does what you want. As more than one person says above, a CGI perl script cannot access resources on the client side.

Besides, isn't this what the "print" button on their browser is for?

The only possible exception (which your situation does not seem to be) is on an internal-only web server (that is, the client is on your network, at your company), and then it could make a system call to print some kind of output of the perl script. However (and this is important), perl is not a web broswer, and so it cannot output to the printer the same thing that a browser would, so this is a bad solution too.
