    Dear Friends,

    I’m working on Epson PLQ22csm, it is a scanner printer. I’m developing code for this printer using twain drivers(TWAINDSM.dll) in vc++.

    I created console application and getting data also but control is not coming from twain GUI to console application until i click on the console application.

    Have you tried looking at the TWAIN Specification under DAT_CALLBACK? This may help.
