O&K Print Watch counts the number of printed pages incorrectly.
First of all make sure that you use the latest version of the program. The number of the supported printer languages as well as their versions is constantly growing. Make sure that your printer driver uses the command language that O&K Print Watch supports. Most printer producing companies provide a number of drivers for their printers. Use the driver with the PCL or Postscript support. If the problem is not solved, please, let us know about it at Support Ticket.
