Calc - How to remove TitleRows (Rows to Repeat) via macro in pyhton? (PrintRepeatRow)

I use this macro to set the line to repeat across pages when printing a spreadsheet. But how do I remove this via macro too?

import uno
from com.sun.star.table import CellRangeAddress

#=========================================================================================
#*****************************************************************************************

def create_instance(name, with_context=False):
    CTX = XSCRIPTCONTEXT.getComponentContext()
    SM = CTX.ServiceManager

    if with_context:
        instance = SM.createInstanceWithContext(name, CTX)
    else:
        instance = SM.createInstance(name)
    return instance

#this works ok
def add_title_row(*args):
    doc = XSCRIPTCONTEXT.getDocument()
    sheets = doc.Sheets

    mysheet = sheets['MySheet']

    title_row = CellRangeAddress()
    title_row.StartRow = 0
    title_row.EndRow = 0
    mysheet. = title_row
    return

#It does not work
def remove_title_row(*args):
    doc = XSCRIPTCONTEXT.getDocument()
    sheets = doc.Sheets

    mysheet = sheets['MySheet']

    #???
    title_row = CellRangeAddress()
    title_row.StartRow = None
    title_row.EndRow = None
    mysheet.TitleRows = title_row
    return

here a simple example file:
test.ods (9,7,KB)

Try:

mysheet.setPrintTitleRows(False)

Thanks this work now:

def remove_title_row(*args):
    doc = XSCRIPTCONTEXT.getDocument()
    sheets = doc.Sheets
    mysheet = sheets['MySheet']

    mysheet.setPrintTitleRows(False)

    return
