The Communications tab gives information about the Parallel or TCP/IP port to which the printer is connected. It contains standard Windows settings related to communication between the computer and the output device. 
- Parallel
Accept the default Timeout settings on this tab. As a troubleshooting technique in Windows NT and Windows 2000, you may wish to increase the size of the Transmission buffer. Because many printers cannot accept data as quickly as a computer sends it, they use a buffer to store information. Increasing the size of the buffer may help in those cases where a particular printer model receives data at a slow rate. The recommended value is 8192 bytes On Windows 98 and Windows ME, the supported buffer size is 2048 bytes. Note that if you select Use standard LPT driver, the throughput may be low and the printer may stop frequently, affecting the quality of the output.
