well, are the extra printers in os 9 when booted into os 9, or in classic apps that are running from the classic enviroment in os x? i'm not to sure on how classic handles printers, being i've never printed from it. i thought it used the os x printer installed. but you could try the way to remove os 9 printers. os 9 keeps all the printer drivers in the extentions folder. so in os 9 open your extentions manager control panel and uncheck the box next to all printers that you do not have. for classic, i believe that there is an option in the classic preference pane that allows you to start classic with the extention manager, and then do the same there, uncheck the box next to all the printers you don't want.
