A 2,000 line per minute parallel impact printer is being installed in a room that is 100 feet (30.48 meters) from the print server. Once connected it does not print reliably. Which of the following…

The correct answer is B. The cable length has exceeded the limit of the standard. Parallel port (IEEE 1284) cables have a maximum recommended cable length of approximately 10 feet (3 meters) for standard mode, or up to about 32 feet (10 meters) for IEEE 1284-compliant cables. At 100 feet, the cable length far exceeds this specification, causing signal…

Question

A 2,000 line per minute parallel impact printer is being installed in a room that is 100 feet (30.48 meters) from the print server. Once connected it does not print reliably. Which of the following is the cause?

Options

AThe cable was installed next to florescent lighting.
BThe cable length has exceeded the limit of the standard.
CThe printer should have been a USB model.
DThe printer I/O logic is faulty and must be replaced.

Explanation

Parallel port (IEEE 1284) cables have a maximum recommended cable length of approximately 10 feet (3 meters) for standard mode, or up to about 32 feet (10 meters) for IEEE 1284-compliant cables. At 100 feet, the cable length far exceeds this specification, causing signal degradation, data errors, and unreliable printing. Parallel signals are susceptible to attenuation and noise over long distances. Fluorescent lighting interference (A) is unlikely to be the primary cause at issue here. USB (C) is not relevant since this is a parallel printer. A faulty I/O logic board (D) would produce consistent failure, not intermittent unreliable printing.
