02 Install and test the Color LaserJet Pro M155a
Check the exact model name
Read the full model name on the printer label. It should match Color LaserJet Pro M155a exactly; printers with similar names can need different software.
Download the package for your system
On HP's support site, choose your operating system version. Pick the full software package for a first-time setup, or just the printer driver if the printer already works with another computer.
Run the installer and connect the printer
Follow the installer prompts for USB or Wi-Fi. For USB, connect the cable only when the installer asks. For Wi-Fi, keep the printer and computer on the same network.
Check that it worked
Print a test page from your system printer settings. If the test page prints, the driver is installed correctly.
03 Troubleshooting
The installer cannot find the printer
Check the connection first. For USB, try another port and cable. For Wi-Fi, make sure the printer shows a network connection on its panel and that your computer is on the same network, then run the installer again.
The printer is installed but shows as offline
Turn the printer off and on, then remove and re-add it in your system printer settings. On Wi-Fi, a changed router or IP address is a common cause.
My operating system is not in the list
Check HP's support site for your exact system version. Newer versions of Windows and macOS often include a built-in driver for older printers, so try adding the printer in system settings first.

Current manufacturer guidance for HP Color LaserJet Pro M155a
The M155a support entry belongs to the M155–M156 series. Its selected Windows 10 64-bit results separate the full software solution from basic or universal driver and firmware categories.
Choose the appropriate setup route
Match M155a, your operating system and the package purpose. Firmware updates and universal drivers are different tasks from the full software solution; generic HP app text does not establish scanning hardware on this model.
