I was going to suggest that you see what a typical Windows PCL driver does by creating a printer using a PCL driver connected to the FILE: device, then print a GDI file containing a bullet, e.g.
//SETOPTION,EMBEDDED-ENTITY-REFERENCES
bullet: •
That does print a bullet character (both in the APEX preview and on paper), but when I tried outputting it to the FILE: device, I ended up with a file 24 blocks long, and I couldn't find the bullet in it.
