@kumar80 Demo:

from PySide6.QtGui import (
    QPageSize,
    QPageLayout,
    QTextBlockFormat,
    QTextCursor,
    QTextDocument,
    QTextFormat,
)
from PySide6.QtWidgets import QApplication
from PySide6.QtPrintSupport import QPrinter, QPrintPreviewDialog


app = QApplication()

dialog = QPrintPreviewDialog()


def handle_paint_requested(printer):
    document = QTextDocument()
    cursor = QTextCursor(document)
    blockFormat = QTextBlockFormat()
    for i in range(1, 11):
        cursor.insertBlock(blockFormat)
        cursor.insertHtml(f"<h1>This is the {i} page</h1>")
        blockFormat.setPageBreakPolicy(QTextFormat.PageBreak_AlwaysBefore)
    document.print_(printer)


dialog.paintRequested.connect(handle_paint_requested)
dialog.exec()

@eyllanesc said in How to print to a printer PySide6:

filename = "test.pdf"

Do we need to create a pdf file before printing it? For my use case will be filling out a form with text boxes and then click on print. In such case is there a way to print without have having an intermediate pdf?

@kumar80 No, it is not necessary, I put 2 codes together but do not eliminate the unnecessary elements. I recommend you test my code by removing that line and you will see that it works. See my updated code.

Sorry to revive this topic but I can't deal with it. For me, the text on the first page is not displayed in the dialog box, but it prints correctly. Why? How to improve it?

@karlowic Your problem is not related to this thread - would be better if you would open your own thread and provide your code.

My post is about the code written by eylanesc in this thread.
This is what Print Preview looks like:

This is what the PDF document looks like after printing:

Print Preview is missing text on the first page but prints correctly. I don't know why this happens, can it be improved?
