Q: When RTG Timer starts up, it says Printer error and when I click OK, it exits.

A: The first time RTG Timer runs, it reads the fonts for the Windows default printer. You will get this message if you don't have any printers defined for this computer.

You must install a printer for your computer, even if you never actually use a printer with this computer. Open the Printers (or Printers and Faxes) folder.  Double-click Add Printer to start the Printer Wizard. Choose "local printer" if you don't actually have a printer for this computer.  Choose "HP" for the manufacturer and "HP LaserJet 4" for the printer. Choose "LPT1:" as the printer port.  Do not print a test page if you don't have a printer attached!
