how to export a angular page into pdf with multiple page - angular6

Question

I have a very lengthy form in angular and i need to convert it into pdf. Since it is a very lengthy form i have to divide it into smaller chunks and show it in multiple pages in pdf. How can i achieve it. And i also need to add header and footer for every page.
I am using jsPDF and dom-to-image packages for pfd conversion.
Following is the code i wrote for pdf conversion:
exportPdf(){
var doc = new jsPDF('potrait','px','a4');
let imageData= new Image();
imageData.src='../../assets/images/testimg.png';
var filename="application";
var options={};
var img;
var newImage;
var node = document.getElementById('formContent');
var numRowsToCut=3;
var imagePieces=[];
domtoimage.toPng(node, { }).then(function(dataUrl)
{
img = new Image();
img.src = dataUrl;
newImage = img.src;
img.onload = function(){
var pdfWidth = img.width;
console.log("image width "+pdfWidth);
var pdfHeight = (img.height)/3;
var width = doc.internal.pageSize.getWidth();
console.log("width "+width);
var height = doc.internal.pageSize.getHeight();
for(var y = 0; y < numRowsToCut; ++y) {
var canvas = document.createElement('canvas');
var context = canvas.getContext('2d');
context.drawImage(newImage, 0, y *pdfHeight, pdfWidth,pdfHeight, 0, 0,pdfWidth,pdfHeight);
imagePieces.push(canvas.toDataURL());
}
var docDefinition = {
content: [{
image: imagePieces[0],
width: 500,
pagebreak:'after'
},
{
image: imagePieces[1],
width: 500,
pagebreak:'after'
},
{
image: imagePieces[0],
width: 500,
pagebreak:'after'
}],
pageBreakBefore: function(currentNode) {
return currentNode.style && currentNode.style.indexOf('myDivClass') > -1;
}
};
pdfMake.createPdf(docDefinition).download(filename);
};
})
.catch(function(error) {
// Error Handling
console.log(error);
});
}
Any help will be appreciated.
