I have just installed BIAB 2020 and discovered the instrumental studies section. I have tried repeatedly to print notation to pdf, loaded the driver, restarted my computer (Windows 10) and each time I attempt to print, I get the message to install the driver. I did some searching on your forums and also installed pdf995. I am still unable to print to pdf. When I try to print the notation to paper, all that prints are a series of / / / /. What am I doing wrong?
