FaxCore PCL Print Spooler Service

The FaxCore PCL Print Spooler (FXC6.PCLPrintSpooler) captures raw network print streams over TCP/IP port 9100, parses embedded routing codes, and submits faxes without requiring file exports.

Installation & Client Setup

1. Run FaxCorePCLPrintSpooler.msi on the FaxCore server to install the service.
2. Ensure embeddedCodesPcl is enabled (value="1") in GatewayAgent.exe.config.
3. On client workstations:
   • Add a new printer using a Standard TCP/IP Port pointing to the FaxCore server IP (Port 9100 Raw).
   • Install the standard HP LaserJet 4000 PCL driver.
   • Name the printer FaxCore PCL Printer.
4. Any PCL document printed to this queue containing ^[D...^] codes is automatically delivered as a fax.
