printing from the sketcher

Hi

I have problems when I want to print a file example.sec ( using wildfire4.0)

I use the command /file/print then a window "print" ask for a printer. But all the printers that are running OK when printing  a .drw file are not listed in this window . Printing a drawing file ( example.rdw ) is Ok

My Question is :

  - can we print a setch file ( .sec) ?

  - if so, it seems that printers for sec files are different from rdw file .

How can I define printers for sketch file ?

Thanks for help
