Raw.exe Sends Binary Data to Printer w/Device Driver


The information in this article applies to:

  • Microsoft Windows Software Development Kit (SDK) 3.1


In the Microsoft Windows environment, device ports are a scarce resource that are shared by all applications running in the system. If an application is designed to send raw, unformatted data to a device port, it should use the Windows Print Spooler to ensure that two or more applications do not use the port at once.


The best method to implement this functionality is by means of a device driver through which an application can pass data to the port without change. Raw.exe is a file in the Microsoft Software Library that contains the source code to a device driver that implements the PASSTHROUGH escape function. The RAW printer driver is intended as a sample driver and has not been designed to be distributed as part of a commercial application.

Microsoft used the most current virus detection software available on the date of posting to scan this file for viruses. Once posted, the file is housed on secure servers that prevent any unauthorized changes to the file.

Earlier versions of the RAW driver were incompatible with Adobe Type Manager (ATM) because ATM requires a printer driver to return a nonzero value when the driver processes the RealizeObject function. The current version of RAW has been updated to be compatible with ATM.
