Thank you for the answer, it realy worked.
But i still have a problem, before i print the invoice to the printer i'm sending the cash drawer comand it opens the cash drawer but spools the print job.When i print the next invoice it prints the spooled job and don't opens the cash drawer. How should i set the spooler options and do i need a special seting or comand in Fox. ( if i set the spooler to directly print to the printer it gives me a error in Fox.

Thanks for you help and have a great new year.
