HP OfficeJet 5255 Scan Connection Issue

[TheBoyWhoLived]

When I go to scan from either the printer or the Easy Scan app, I get a connection error on the computer or the printer tells me I need to visit 123.hp to get the latest software/driver (title of message "Software Required"). When I go to HP Utility app, I can connect to the printer to do everything else (check ink levels, clean heads, etc), but going to Scan to Computer I get a communication error. All it says is check cables and connection settings, and restart the devices. I have done all of this but it still will not work. Scan was working a month or two ago. I downloaded the latest firmware for it but it said it did not need it when I tried to run the update.

Hi @TheBoyWhoLived,

Since HP Utility works but Scan to Computer fails on macOS Tahoe, the scan driver (HP Easy Scan) is outdated or blocked, not the network.

Option 1 – Scan with macOS tools

1. Open Finder > Applications > Image Capture, select the OfficeJet 5255 and click Scan.
2. Or go to System Settings > Printers & Scanners > select the printer > Open Scanner.

Option 2 – Reinstall the HP software

1. Remove the printer in System Settings > Printers & Scanners and add it again with + (choose AirPrint).
2. Install the HP app from the Mac App Store, sign in and add the printer, then use Scan in the app.
3. If macOS asks to allow HP software during installation, approve it in System Settings > Privacy & Security.

The "Software Required" message on the printer refers to Scan to Computer, which needs HP software on the Mac; Image Capture or the HP app replace it.

Let me know how it goes!

Hi @GOLD_MASTER,

I tried the following:

I ran Image Capture, but when I try to Scan  I get an error message saying "Failed to open a connection to the device (-21345)."
Same goes for going through the Printers & Scanners option. The printer status is green, idle. I tried re-adding the printer but the same error occurs.
