// The format for requesting PDF data is as follows:

//
// Parameters (< > required):
// <PrintPreviewUIAddrStr> = Print preview UI identifier.
// <PageIndex> = Page index is zero-based or

//
// Example:
// chrome://print/0xab0123ef/10/print.pdf
//
// Requests to chrome://print with paths not ending in /print.pdf are used
// to return the markup or other resources for the print preview page itself.
