I would like a Software where to adjust all my stuff to be printed, BUT the final step, instead ti send all to my printer, send it to my Penn Drive , so to be printed by a professional shop...
I was lookinf for this in the LR module but nothing
You might want to explain in a little more detail exactly what you are trying to accomplish. For example, what are you trying to do that you cannot accomplish by just sending a Jpeg or TIF file to the print shop?
That said, I'll go ahead and mention two things you may want to look into:
1. You can use the Print Module in LR and print to a Jpeg. This allows you to use the different layout templates and you can also use special ICC profiles if necessary.
2. Qimage has always been a very popular pre-print processor. It isn't mentioned as much these days due to advances in software like Photoshop and Lightroom but it is still being sold.
As Eyeball said, it is not clear what you feel is lacking from LR. I do this with LR by printing to JPEG. you could also export to TIFF or other formats.
