RemoteScan – Seamless scanner connectivity for virtual desktop environments

An article that provides details on Quest RemoteScan that is now part of the Quest Desktop Virtualization Group (vWorkspace).

Since 2004 RemoteScan has been the trusted name for document scanning solutions within distributed network environments.  RemoteScan software enables any TWAIN or WIA compliant device to be used over any RDP, VDI, EOP/EOP Xtream or ICA/HDX network environment, with any application that uses TWAIN or ISIS image acquisition. RemoteScan offers an extremely stable, seamless, and secure option for scanning that has become the solution of choice for the medical industry. Since RemoteScan rides over the RDP (or ICA/HDX) channel, it inherits whatever security is in place there. RemoteScan also turns any scanner into a network device to be shared with any number of scannerless workstations, offering significant cost savings. RemoteScan can work with any XPe or Windows Embedded standard thin clients. The below diagram demonstrates some of the configurations in which RemoteScan can be used.


How does RemoteScan work?

Anyone using vWorkspace, Terminal Services (or Citrix) will at some point run into a need for RemoteScan. Variables amongst scanner drivers and operating systems and flavors of mix and match virtual environments become a non-issue for users of RemoteScan. RemoteScan makes it easy: from a workflow perspective, the end user can simply log into their remote session and access whatever application they need to use to scan, whether it is an EMR software package like NextGen, or a scanning package like Adobe Acrobat, etc. The application detects the scanner as though the end user is scanning from within a local application. The end user then drives the scan, and saves the image to whatever folder necessary on the server, using whatever file formats are native to the application that is being used to scan. Lossless compression and defaults and templates that control color depth, dpi, and image dimensions provide fast transfer rates over the virtual channel. Alternately, in VPN environments, endusers can choose to use direct IP connection for even faster results. We have been able to achieve great results with speed - in many cases 100+ pages a minute for black and white images.

While RemoteScan has become the gold standard for image acquisition in virtual environments, project managers are too often caught by surprise that scanners and cameras are not by default usable over virtual networks. This oversight can create substantial budgetary snags and delays in completing a project. This is not trivial - scanning and image acquisition are essential workflow functions, especially in medical, financial, government, and transportation sectors.  Stability and open ended flexibility are the hallmarks of RemoteScan, and the reason RemoteScan is widely used and recommended by all of the major EMR companies.
