Using a Dot Matrix Printer as an Alarm Printer with Sigma on Windows 7

[Product_Support]

Issue

The Epson LQ-300+ II dot matrix printer fails to print alarms correctly when configured with Sigma on Windows 7. Alarms are spooled but not printed unless manual changes are made in Sigma's Alarm Manager.

Product Line

Satchwell BAS & Sigma

Environment

• Epson LQ-300+ II
• Satchwell Sigma
• Windows 7 64-bit

Cause

When the printer is set to Continuous Print, Sigma spools the alarms, but the printer does not initiate printing. This issue is linked to driver compatibility and printer configuration settings.

Resolution

To resolve the issue and enable reliable alarm printing:

1. Remove Existing Printer Configuration

   • Go to Devices and Printers.
   • Remove the Epson LQ-300+ II printer.

2. Reinstall the Printer

   • Use Add Printer to reinstall.
   • Important: Use the Windows XP 32-bit driver from the original CD.
   • Do not use the Windows 7 driver, as it causes compatibility issues.

3. Configure Printer Settings

   • Go to Printer Properties > Advanced tab.
   • Set Print Processor to: Raw [FF auto].
   • Set the printer to Spool directly to the printer.
   • Choose appropriate paper type: Fanfold or A4.

4. Clean Up Sigma Configuration

   • Shut down Sigma Client and Sigma Server.
   • Navigate to C:\sigma\data and delete the file: printerconfigs nn.rec.
     • This removes outdated printer references and avoids confusion.

5. Reassign Printer in Sigma

   • Restart Sigma Server and Sigma Client.
   • In Alarm Manager, highlight and reassign the printer.
   • Set to Continuous Print.

     Tick the LF (Line Feed) and CR (Carriage Return) boxes.
