Export to pdf A4 page break problem

Hi!
I have noticed that if I resize letters on pdf export to A4 format then the pdf page breaks not at the bottom of the page, but in the middle of it. I tried setting paper size numerically but it does not help either.
So, I have a Plumsail form on a Sharepoint list. I put the Title field, an HTML control and a button on it. In the HTML control I have a long random text. In the custom JS have a function attached to the onclick event of the button. This function exports the form to A4 sized PDF when the button is clicked. In the custom css I hide the button on pdf export and also resize all font to 10px. The exported pdf gets broken up in the middle of the page. How to overcome this problem?

<p>"But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?"</p>

Et harum quidem rerum facilis est et expedita distinctio. Nam libero tempore, cum soluta nobis est eligendi optio cumque nihil impedit quo minus id quod maxime placeat facere possimus, omnis voluptas assumenda est, omnis dolor repellendus. Temporibus autem quibusdam et aut officiis debitis aut rerum necessitatibus saepe eveniet ut et voluptates repudiandae sint et molestiae non recusandae. Itaque earum rerum hic tenetur a sapiente delectus, ut aut reiciendis voluptatibus maiores alias consequatur aut perferendis doloribus asperiores repellat."</p>

<p>"On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains."</p>

custom JS:

async function toPDF() {
  fd.exportToPDF(`Test.pdf`, {
    paperSize: "A4",
    margin: "0mm",
    landscape: false,
  });
}
fd.control("btnPDF").onclick = "toPDF();";

custom CSS:

.k-pdf-export button {
  display: none !important;
}

.k-pdf-export * {
  color: green !important;
  font-size: 10px !important;
}

Thanks for looking into this.

Hey @Janos_Nagy,

Does it work fine if you comment out the font-size property?

Hey @IliaLazarevskii ,
yes, if I comment font-size property out, then it seems to work well.

Hi @Janos_Nagy,

I reproduced the issue, we're working on finding out the cause. I'll get back to you as soon as we pin it down.

Hi @Janos_Nagy,

In this case, the positions of page breaks are calculated before applying the CSS class. You can work around the problem with code like this:

$('.text-element').addClass('pre-print');

setTimeout(function() {
	fd.exportToPDF('Name of the resulting PDF', {
		landscape: false,
		paperSize: 'A4',
		forcePageBreak: ".breaker",
		multiPage: false,
		margin: '0mm'
	});
}, 1000);

setTimeout(function() { // Remove the class "pre-print" from all elements
	$('.my-element').removeClass('pre-print');
}, 2000);

This code temporarily applies the pre-print class to all elements with text-element class and removes it after the form is exported.

The pre-print should contain all styles you want to apply to the form elements:

.pre-print {
  color: green !important;
  font-size: 10px !important;
}

Let me know if this helps.

Hi!
It kind of works. In the css I had to add an asterisk to change everything to the target font-size:

.pre-print * {
  color: green !important;
  font-size: 10px !important;
}

By your solution the page breaks at the bottom, however, it can break letters in half:

I do not want to put in page breaks manually as on some forms the text length may vary and it is impossible to pre-calculate where the breaks should go.
Any ideas on how to avoid this?

Hey @Janos_Nagy,

I suspect that this happens due to the PDF export settings. Maybe increasing the margin: '0mm' property in the JavaScript code could help?

Another thing you could try is to add a border to all elements with this style:

border: 1px solid #000000;

This probably won't solve the issue, but seeing where the elements end might be helpful.

Hi!
It does not work. I increased the margin to 10mm and added the border attribute to the css. The pdf export still breaks the letters:

Anything else I can try?

Hey @Janos_Nagy,

It turns out, it's a limitation of Kendo UI.
You can try the solution from this post: https://www.telerik.com/forums/kendo-pdf-export-cut-off-the-table-content

But a much safer bet would be to create the PDF from a template: Generate PDF from DOCX template with Plumsail Processes — SharePoint forms

Dear @IliaLazarevskii,
we do not have Plumsail Documents. The telerik solution is not ideal as you wrote as well.
Thank you anyway!
