Printer Keeps On Changing In Libre Office


I am new to Libre office and is recently facing a strange kind of problem. I have 3 different printers installed however only one was default which I mainly use for printing. Recently the default printer keeps on changing and some errors occurs and the printing task gets cancelled.

I am a bit confused that whether I need to set the default printer from inside windows, or there would be some option inside libre offce to do the same. I have found a link which says it needs to be done from inside the Windows. A small guide from the community will be really helpful.

Thank Guys!
