>My application needs to print directly to a printer located at long distance (5 km) of our office. It works but take 1 minute by page. And it's really too long for the user to wait as long. How can I do REPORT FORM with NOWAIT?
>Could I use DLL, service or any technical solution to print without wait in main application?

One solution would be to print into a file (hopefully it would be fast) and later send the files to a printer in a remote site. You can use COM for that if needed. Check RawPrint class from Downloads section here.
