Print to PDF Resolution

Is there a way to permanently change your Microstation printer to pdf preferences? I would like my resolution to change from 1200 dpi to 300 dpi automatically when printing out drawings to pdf, as this would save a lot of time when printing out many sets of drawings individually. I currently manually change it to 300 dpi through the printer settings every time I have to print each drawing. Please let me know if this is possible. thank you.
