Answer:
Option B, incorrect printer driver, could also cause printing issues, but since Steve was able to print a test page earlier, this is less likely to be the issue. Option C, Steve not being connected to the network, is also unlikely since he was able to print earlier in the day. Option D, Janice not being connected to the network, is also possible, but less likely than option A since Janice's computer is the one hosting the shared printer.
