MSTSCAX
MSTSCAX.DLL is the Terminal Services Client ActiveX Control. With regard to printing, it is a TS client-side component that implements the RDP Virtual Channel for redirected printing. The client-side RDPDR subcomponent within MSTSCAX.DLL enumerates printers on the client and announces them to the server. Printers are enumerated using the EnumPrinters() API. In RDP 5.0, only printers connected locally to the client machine via COM, Serial, or USB ports are redirected in Terminal Server sessions.
The printers automatically detected via the EnumPrinters() API are always called automatic printer queues. The client sends data for each enumerated printer, including printer name, printer type (for example, network or local), driver name, and any configuration data, such as paper orientation (portrait or landscape) or number of pages per sheet, that was previously saved by the client in the registry.
In addition to the printers that were automatically detected, the client also announces printers that were manually created in a previous session by the user or administrator. These printers were persisted by the client in the registry (see Details of Queue Configuration Changes). These manual printer queues from the previous session now are automatically announced to the server by MSTSCAX.DLL (client RDPDR.LIB) and can now be viewed as automatic printer queues.
