Yes, and it was the function I used as basis.

But it's static, and I thougth, trying to read hprinter.prg that there
was a way to create a file when creating the print job, and there where
a way to then print it.

METHOD LoadScript( cScriptFile )
METHOD SaveScript( cScriptFile )
 
Then it needs only the structure of the scriptfile to make it usable.
Exactly as source code ?

Thanks
