Home › Forums › TWAIN Classic › Setting CAP_DUPLEXENABLED failures
Follow up to my Query get State message really.
I finally (I think!) pinned down my failures to trying to set
CAP_DUPLEXENABLED to True when CAP_XFERCOUNT = 1.
It returned TWCC_BADCAP (which as a 1.9 driver it should never).
While this might make some sense on the surface, as the TWAIN spec. says that
CAP_DUPLEXENABLED should be set before
CAP_XFERCOUNT this seems to be an error.
I also checked and setting CAP_XFERCOUNT to 3 did not seem to be a problem.
Seems to me if 1 croaked so should 3.
FYI: Scanner is Canon DR-2510C.
