I have the Adobe Creative Suite and an AGFA 1212u scanner. I have downloaded the OSX ScanWise software for the scanner, and was to able to get scanning directly to PhotoShop to work by placing the ScanWise plugin in the appropriate plugins directory for PhotoShop.
My question is this: Acrobat 6.0 Professional has a Create PDF From Scanner... menu option, that brings up a device list. I cannot seem to figure out how to install my scanner so that it shows up in this list allowing me to scan directly to a PDF. I know that you are supposed to be able to use the PhotoShop plugin to enable the Acrobat scanning, I just don't know where to place the plugin to make Acrobat recognize it, and thorough searches of Adobe's support site doesn't seem t bring anything relevant up (it's mostly directed at Windows.)
I've been using the two step process so far, I just thought it would be nice to do it all in one step.
I saw a Adobe Support Knowledgebase article that said Acrobat 4 or greater supported Photoshop plugins. After placing a posting up in the Adobe forums for this same question, I got a reply back that the Knowledgebase article is incorrect and that yes you do need a TWAIN compliant driver to scan to Acrobat.
Someone suggested the SANE website for setting up a workaround for scanners but I haven't had a chance to check it out yet.
