There are two BJ10sx drivers. One comes with the latest Workbench disk
(CanonBJ10). This is basicly a driver made by Canon (or me) and used by Commo.
The driver is also available in a MUCH more recent version on the CanonDisk
V3.10 here on CIS in the AmigaUser forum library. So download the CanonDisk
V3.10. Everything is on there
