smartform: Please maintain an output device in your user master data

I am using smartforms to send an email.  If I remove the printer from my master data and I run my program in the background, I get the error 'Please maintain an output device in your user master data'.  If I run it in the foreground I do not get the error.  This will be a background job and that user does not have an output device.    Here are my output settings.

  l_output_options-xsf        = 'X'.      " XSF Output active

  l_output_options-xsfcmode   = 'X'.      " Get XSF params from program

  l_output_options-xsfoutmode = 'A'.      " Application

  CLEAR l_output_options-xsfoutdev.

  l_output_options-xsfformat  = 'X'.      " Formatting ON

  l_output_options-tdimmed = space.

  l_output_options-tdnewid = space.

  l_control_parameters-no_dialog = 'X'.

Please help!
