Twain driver concurrent requests -

-

it's possible use 1 twain driver manage concurrent request 2 different multifunction printer?

i mean, if have 2 mfps , can 2 scan request in paralel using same twain driver?

it depends on if driver supports it.

from twain spec page 125: if application attempts connect source supports single connection when source opened, source should respond twrc_failure , twcc_maxconnections.

also spec on page 212: source responsible managing this, not source manager (the source manager not know in advance how many connections source support).

i tested fujitsu fi-7260 scanner , got twcc_maxconnections error twacker:
