In TOPAZ -> SETUP -> PROPERTIES -> PABX,
"run every" ? "minutes".
If you entered a 4-digit number as the minutes,
for example 1440, to import every 24 hours,
you will get the range check error.
This has been fixed in TOPAZ 1.7.5.5 or newer.
Make sure the printer driver is installed and working.
Make a test print from Windows to the TOPAZ printer.
