That's pretty much what I used to do. The nice thing about gscan2pdf's way of doing it is that it copes with the second sides being scanned in reverse order if you use an ADF. You could script that, but when someone has already done it, laziness... I mean efficiency, wins. --=20 Neil Bothwick Anything is possible if you don't know what you are talking about. --Sig_/UakZOakHOgnFdWKH1HTMlUq Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE8k9T/rX16EJxEKG692eFu0QSMJgFAl/R6aoACgkQ92eFu0QS MJhZFxAArdA1yMWRf+TloejYEkgTUEhXzNUfnU2W6TOzcnWL03buTcREMHQdD9Go MPEHioUYajvr7kNSDBEcPZn4dhCSSioNKdd0Po9v7FmCsjbCDv0o59qhFmCtVpW5 57jK9bi7896MHZVs7fMEIhnouxAO9pkW5MUMgX3SHIOqGX+p/M33jytz30ZQaWMq xrt4BOX4dlgMY8iFfuu6UNkc+wkRXFvvCAWh305ILS3rkjCGjVtxedVvosCUyVy0 dttO/nuZ1DTT3EDmMtNYL32w4a5/AYpuPE8iWLqABrECK+k8XShvAYfriUDZDpMK nrJCTgxNWC3zB4koYEebdaT/Ausxbbq+Dj3BQ3vrzh35TXxcvQrTaD6Ia/nUbAfe GbtJQHtFKevJypBwtdCsjN5JetT5E96AUY3YUd9H73RaAjtVXqujRUataDe5m62M XoYHUVZrUEMTdMxvk1kqMVIp6poMawQjDMwSSnZG6C6HgMBdpDyD5+GBKPY5bL7J hr1zN7Ya47mp7GHx3wmPA2Y84hzmq+i3WSbQEAU1w1KRY4J+L/iDSm8cMty1TDAl hUci5kyjAuj1lBHRN0UWQ2TpdYACj+5caI8fqEkMcRVFjwiSYzbWBxNfpEeeQhqe Pe9CYqKtriAXA/HSHuh+iloJz4+Qx3xq6TrU0J+/R0VznhpSlD8= =3fsW -----END PGP SIGNATURE----- --Sig_/UakZOakHOgnFdWKH1HTMlUq--
