ReportBuilder renders to the printer using the Delphi TCanvas class and via calls to Windows GDI functions.
We do not have any direct experience with sending escape codes directly to the printer driver. According to the Windows API documentation, the ExtEscape function allows applications to access capabilities of a particular device that are not available through GDI. Try searching the Windows API docs and Google for more information.
The question here is that the client is attempting to print a signature stored in a printer DIMM. The signature printing is triggered by a specific PCL command sent to the printer. Thus, the question is how to send PCL commands to the printer? This seems like a common enough situation given check printing security. Do you have a tech tip or how have other users of ReportBuilder solved this problem?
