we publish one app using citrix xenapp 7.17 for POC all on one physical server.its working fine and printing fine.the only problem that we are unable to scan from the published apps.its giving the message that unable to find the appropriate scanner.
i installed the twain compatible driver for the scanner on the client PC .i test the drivers working fine by disabling the WIA service and test the scan.i double check the USB redirection policies enabled and compression set to medium.i use twaker on server and client machine to check the scanner but did not see my scanner to acquire.i also check by copying the user.dll to user profile on citrix server but no luck
locally the scanner is working fine with application without citrix xenapp.
scanner is cannon
