These steps are to be performed on the PC being configured with POS closed

1. Install the Logic Control USB support package to create a virtual com port. This step is not needed if you are converting an existing OPOS printer to a windows printer.
2. Remove the current Logic Control OPOS for .net software from the system if one exists:
   1. Go Control Panel, Add/Remove Software.
   2. Find the Logic Controls OPOS for .net entry. (I am not sure of the exact name)
   3. Remove the software.
3. Identify the virtual com port currently being used by the display post:
   1. Press the Windows Start button and select Devices and Printers
   2. There should be a line in the unspecified area that is labeled LCI Line Display.
   3. Make a note of the device name and COM port number in parentheses. This will be used latter.
4. Add the display post as a printer.
   1. Press the Windows Start button and select Devices and Printers
   2. Select Add a Print on the top of the page.
   3. Choose Add a local printer.
   4. On the Choose a port screen select the “Use existing port” radio button.
   5. Use the pull down menu on the port and select the port that was found above. This will most likely just say COMx.
   6. Press Next.
   7. Select the manufacturer “Generic”
   8. Select the printer “Generic / Text Only”
   9. Press Next.
   10. If you are prompted to update the driver select Use Current Driver.
   11. Give the printer a name. I called mine “Display Post”.
   12. Select Next
   13. Choose Do not share this printer.
   14. Select next.
   15. Uncheck the “Set as Default Printer” box.
   16. Print a test page and the page should write messages across the display.
   17. Select Finish.
5. Change the PC settings to use the new display post:
   1. Launch [i]merchant
   2. Select Tools, Administration, PC Settings
   3. Find the PC you are on and select properties.
   4. Change the Display Post to “WindowsPost” and make sure the Use box is checked.
   5. In the right box, change the POS Display Post Printer to the printer we just added.
   6. Set the characters per line to 20.
   7. Save the Settings.
   8. Select Test Devices and test the display post, you should see a test message.

If for some reason the post does not work.

Make sure you uncheck the Use box next to the display post before starting the register.
