How does printing of a smartform through standard tcode works?

Hi Experts,

I have attached successfully the customized sales invoice smartform to the tcode vf03. Currenly, client is taking print out through the customized tcode. They want to take it out from the standard tcodes. But the steps are long enough. Please check the following screenshots as how it is working currently:

1. goto vf02 (click on issue output to, the following status comes and print icon is disabled)

2.Click Enter..Goto---header----output

Enter the details and save it. (for a particular invoice number)

3. Click on issue output to.

4. Click on print preview/print then it shows the smartform

My question is that if the customer wants to take the printouts, do they have to follow these 4 steps for each invoice numbers? If yes, they prefer customized tcode. Please do let me how it all works?

Regards

Mani
