Request: Print settings

I need set print settings but there are no functions on this API to achieve it.

I think that the implementation could be like worksheet.tabcolor() function.

Exceljs (https://github.com/guyonroche/exceljs) has implemented this by this PR: https://github.com/guyonroche/exceljs/pull/105

i’ll work on this if @dtjohnson does not have time 😃 i could use it in my project as well anyway

sheet1.xml

<printOptions horizontalCentered="1" verticalCentered="1"/>
<pageMargins left="0.5" right="0.5" top="0.5" bottom="0.5" header="0.5" footer="0.36"/>
<pageSetup scale="77" orientation="portrait" r:id="rId1"/>

printOptionsNode:

// Create the Print Options.
        this._printOptionsNode = xmlq.findChild(this._node, "printOptions");
        if (this._printOptionsNode) {
            xmlq.removeChild(this._node, this._printOptionsNode);
        } else {
            this._printOptionsNode = {
                name: 'printOptions', attributes: {
                    paperSize: 9,
                    scale: 100,
                    firstPageNumber: firstPageNumber || 0,
                    fitToWidth: 1,
                    fitToHeight: 1,
                    pageOrder: 'downThenOver',
                    orientation: 'portrait',
                    usePrinterDefaults: 'false',
                    blackAndWhite: 'false',
                    draft: 'false',
                    cellComments: 'none',
                    useFirstPageNumber: 'false',
                    horizontalDpi: 300,
                    verticalDpi: 300,
                    copies: 1
                }, children: []
            };
        }

Can you please help me add a header and footer to all pages while printing?
