The PRINT FORM command does not have a parameter to print User Forms created by the CREATE USER FORM command. To print these forms the PRINT RECORD and PRINT SELECTION commands must be used.

This is possible because OUTPUT FORM has an optional third parameter which allows developers to specify User Forms as the output form. For documentation on how to use OUTPUT FORM in this manner see the 4D Online Documentation at the following link:
