The port is Ok.

Look... The printer is a Bar Code Printer... I just want to know if there's a kind of initialization that must be done before send the reports to print. When I installed the Windows Drivers for this printer, I though that I can do a report in the report designer, and send it to the printer. I just want you to know if there's an special command I must send to printer before the printing so it could recognize the report. Maybe the printer mode EPP/ECP/SPP... an Idea please.
