While we find it a lot easier to batch scab a bundle of papers and afterwards match them to individual patients, you can do what you want by connecting your scanner via SANE and using a SANE-TWAIN bridge on the Windows computer / CITRIX terminal session (if you have Macs or Linux/BSD, you should be able to use SANE directly) http://sane-project.org/ - you'll have to search that web site a bit for instructions how to run it on non-POSIX platforms and where to find the SANE-TWAIN bridge SANE is network capable, that is you can address a scanner via network address instead of USB or SCSI interface - like addressing a printer via print server. In my practice, we can access any scanner in any room from any computer / terminal session just as we can access any printer I quote from SANE's web site: """If you're familiar with TWAIN, you may wonder why there is a need for SANE. Simply put, TWAIN does not separate the user-interface from the driver of a device. This, unfortunately, makes it difficult, if not impossible, to provide network transparent access to image acquisition devices (which is useful if you have a LAN full of machines, but scanners connected to only one or two machines; it's obviously also useful for remote-controlled cameras and such). It also means that any particular TWAIN driver is pretty much married to a particular GUI API (be it Win32 or the Mac API). In contrast, SANE cleanly separates device controls from their representation in a user-interface. As a result, SANE has no difficulty supporting command-line driven interfaces or network-transparent scanning. For these reasons, it is unlikely that there will ever be a SANE backend that can talk to a TWAIN driver. The converse is no problem though: it is pretty straight forward to access SANE devices through a TWAIN source.
