// PrintPreviewDataSource serves data for chrome://print requests.
//
// The format for requesting PDF data is as follows:
// chrome://print/<PrintPreviewUIAddrStr>/<PageIndex>/print.pdf
//
// Parameters (< > required):
//    <PrintPreviewUIAddrStr> = Print preview UI identifier.
//    <PageIndex> = Page index is zero-based or
//                  |printing::COMPLETE_PREVIEW_DOCUMENT_INDEX| to represent
//                  a print ready PDF.
//
// 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.
