output type in SAP Script

hi all,

what is this output type?why it is needed?

i have developed a print prog for exise invoice

but not used output type anywhere to see the output of the form.

so my question is when this output type is reqired and when not?

whther i should create output type for the above print program also. whether it is good practice to have output type? if yes why and how can we create output type for my above program?

thanks & regards

sanjeev
