Locking a document when printing?

Hi Gurus,

I hope you can help me with this issue.

I made a customized printing program in ABAP that will print a certain document. My requirement is, I need to prohibit/lock the document to be printed until SAP is done passing the spool request to the printer. I tried to research the concept of enqueue and dequeue but I guess i need sample code for customized programs so that I can understand it.

I hope you can help me with this requirement.

Thanks,
