Я нашел лучшее и простое решение:
<script type="text/javascript" language="javascript" src="//cdn.rawgit.com/bpampuch/pdfmake/0.1.26/build/pdfmake.min.js"> </script>
<script type="text/javascript" language="javascript" src="//cdn.rawgit.com/bpampuch/pdfmake/0.1.26/build/vfs_fonts.js"></script>
grid.jqGrid('navGrid', '#ptoolbar', { pdf: true } );
grid.jqGrid('navButtonAdd', '#ptoolbar', {
id:'ExportToPDF',
caption:'',
title:'Export To Pdf',
onClickButton : function(e)
{
try {
// ExportPDF();
$("#orwellRadnici").jqGrid("exportToPdf",{
title: 'PDF Export',
orientation: 'landscape',
pageSize: 'A3',
description: 'Events',
customSettings: null,
download: 'download',
includeLabels : true,
includeGroupHeader : true,
includeFooter: true,
fileName : "File.pdf"
})
} catch (e) {
alert(e);
}
},
buttonicon: 'ui-icon-print'
});
И это все!
