Windows Process Description:

SoftCopy is a virtual printer driver that produces output in JPEG, BMP, PNG, TIFF as well as PDF image formats. After its installation, SoftCopy appears just like another printer available to all your applications so that when you print, you can choose to write the output to any of the supported image formats and you decide which image format you want to write to at the point of final output.

SoftCopy supports an unattended operation through the extension.dll module. This DLL always provides the SoftCopy application with the filename and the image format for each output file instead of asking the user to specify them interactively. When a job is completed, SoftCopy calls on the extension.dll application to perform any post-processing operations such as displaying an alert to the user, etc.

The extension.dll file comes with the default installation of the software that allows you to configure it according to your unique application requirements. A GUI configuration tool is provided to make it easier for you to install/configure the file extension.dll without having to use the command prompt or manually edit the registry.

However, you can install the file extension.dll by modifying the Windows registry directly, by adding a string value of HKLM/ Software/ DobySoft/ SoftCopy/ ExtDllPath in the Windows registry. These values should be the full path to the extension.dll file such as C:/ Program Files/ SoftCopy/ extension/ Release/.

Simply submit a sample print job to the SoftCopy application in order to check if the extension.dll process is working. If the output file is immediately displayed, then the extension.dll application is working correctly. However, if the dialog box "Save as" continues to pop up, then you need to recheck either the extension.dll process or the installation is properly configured.

The module extension.dll interface has changed with SoftCopy V3. Its most important change is the scEndOfJob function that takes a single SCFILEINFO* pointer as an input parameter. If you export the scEndOfJob function in the extension.dll file, the function interface must be changed and recompiled, otherwise the print driver may crash.
