Computer Applications
Shobha recently got a printer as a gift. She has connected the printer to her computer as well as to the power source. Everything seems to be in order but when she tries to print, the printer does not show up in her list of devices. What could be the problem? Can you suggest what Shobha can do to resolve this issue?
Answer
A possible issue can be that Shobha's computer cannot recognise the new printer. She can resolve this issue by following the given possible solutions:
- She can install the necessary printer drivers on the computer. Sometimes, printers require specific drivers to communicate with the operating system. She can check the printer manufacturer's website for the latest drivers and install them.
- Sometimes antivirus software or firewall blocks the communication between the computer and the printer. If the drivers for the printer are installed correctly and still it is not showing up in the list of devices, then Shobha can temporarily disable the antivirus/firewall to quickly check if that is causing the issue.
