Take a look at Message #550173.

>Well, for the sake of simplicity, in my situation it's essentially the following list of commands:
>
>. sys(1037)
>. report form x1 to printer
>. report form x2 to printer
>. report form x3 to printer
>
>In this case the printer has an option to send the output as a fax. It's a Xerox Docuprinter. So, when sys(1037) is called the user can change printersettings and thus will have the opportunity to direct the output to a fax.
>When report x1 is sent, the user will be confronted with the Docuprinter-controlled dialog where a telephone number must be entered. That's okay.
>But that same dialog appears for x2 and x3. Cut-and-paste of the telephone number might help, but it remains a 3-time dial of the Docuprinter.
