Hi,
Looking in the help for PrintTextFile() it states that "Newline/carriage-return characters are honored" however it does not talks about form-feed characters. It is possible that it does not process form-feed commands.
There is the chance that changing the ATTR_EJECT_AFTER attribute in the SetPrintAttribute() will cause the form-feed to be honored. You may want to give this a try. Otherwise; you can read the text file into memory, separate the buffer into blocks devided by the form-feed characters and then use the PrintTextBuffer() function.
I hope this helps, let me know if you have any furhter questions.
