Richard, thanks for quick response.

Anyway, it seems it's not because of the driver, but it's because of the bios setup for LPT1 mode.
My machine is Dell Optiplex 745 and it has LPT1 mode as EPP/ECP/IBM AT/IBM PS/2. By default it sets as IBM PS/2.
By changing to ECP, it works now.

thanks again.

rgds,
