i tried to use QtPrintSupport
it works fine with html content but image doesn't shows up

from PyQt5 import QtPrintSupport

self.editor = QTextEdit(self)
self.editor.setHtml(html_page_var)
dialog = QtPrintSupport.QPrintPreviewDialog()
dialog.paintRequested.connect(self.editor.print_)
dialog.exec_()
