Check printed with dots instead of commas

Hi everyone,

I´m facing a problem with the amount format of some checks, when I look at the check in SAP the amount is correct, for example: $20,123.45 but when I send the check to the printer, the amount changes to $20.123.45. As you can see, the comma used is changed by a dot so the check is denied becuase the amount format is incorrect.

Do you have any ideas why this is happening?

Thanks!!
