It is an error to specify a range with start greater than end.

Should be valid HTML markup with following classes used to inject printing values into them: - ```date````: formatted print date - ````title````: document title - ````url````: document location - ````pageNumber````: current page number - ````totalPages````: total pages in the document  For example, ````<span class=title></span>```` would generate span containing the title.

    :param prefer_css_page_size: *(Optional)* Whether or not to prefer page size as defined by css. Defaults to false, in which case the content will be scaled to fit the paper size.
    :param transfer_mode: **(EXPERIMENTAL)** *(Optional)* return as stream

        0. **data** - Base64-encoded pdf data. Empty if `` returnAsStream` is specified.
        1. **stream** - *(Optional)* A handle of the stream that holds resulting PDF data.
