Moreover, if you’ve been using a front USB port to connect the PC and printer,try a rear port instead.Front USB ports are connected to the mainboard through normal copper cables.

On the other hand, rear ones are embedded directly into the motherboard PCB so they’re often more durable and work faster.

Restart Print Spooler Service

Fix Wi-Fi Connectivity

If you’re facing Error Code 45 with a wireless printer that connects to Wi-Fi, do the following. However, this will only work if you know the Wi-Fi network name or its password.

Fix Ethernet Connectivity

When your printer is in a network for shared usage, it uses an IP address to communicate with all the PCs in the network.

Any issue with this IP address allocation might prevent the printer from communicating with the PC.

Eventually, the Device Manager tool shows Error Code 45 because it thinks that the printer isn’t connected. So, you’ll need to re-establish the IP configuration to nullify any issue related to the network setup. Here’s how:

Try printing a test page on the printer.

Update Printer Driver

Once it’s done, reboot the PC and try printing a page.

An easier way to update drivers is to use a specialized tool such asPC HelpSoft Driver Updater. This software will allow you to scan for and automatically update any drivers in just a few minutes.

Run the Printer Troubleshooter

Use System File Checker (SFC) Scan

Try doing an SFC scan to find out if the Error Code 45 printer issue is caused by system file integrity problems:

Perform a DISM Scan

If there’s indeed an issue with the system files, the terminal will show you the result that indicates you must follow the DISM Repair Process. Here’s how:

Sometimes, Windows Registry directory issues can cause printer errors. In such a case, you must restore the registry to its last known working configuration. If you’ve created aWindows Registry backupfile, you can easily restore it with that.

If you didn’t, you can try a third-partyWindows Registry repair toollike theGlary Utilities Proapp. Download and install it on your PC and follow these steps:
