- I think BIOS routines works only in 80x25 mode. If you want to have it
- working in a graphic mode, you have to load the program GRAPHICS (if I
- remember well), which will setup a new routine for graphic printing (on an
- IBM compatible printer :( ). I *guess* it is the same problem for 80x50
- text mode, but I don't know if the answer is the same. Why about trying ?
