LaserJet Pro CP1525n keeps going offline

[cvhmanchester]

When switching on the computer and printer in the morning, I can print. However after a couple of hours, the printer goes off-line and nothing gets printed.  I then run HP Print and scan doctor, which says it has fixed the problem (i.e. deleted the print queue) and suggests that I print a test page.  Which just joins the unprinted print queue. 

When I go to printer>properties, the offline option is  greyed out.  If I go to Administrator, the offiline option is in black, but the printer is still offline. 

This has been happening every day for a week.  I have tried to uninstall and reinstall software, but it seems impossible to delete completely all traces of the printer driver.

How do I get the printer to stay online?

Kudos to you for trying out the steps before reaching out to us.

Hard reset on the printer, router, computer and other devices on the same network.

The following steps temporarily disconnect network and Internet connections and require restarting your computer. Complete any tasks or downloads in progress before continuing.

1. Press the Power button on the printer to turn it off.

2. Disconnect the power cord from the rear of the printer.

3. Disconnect the power cord from the wireless router.

4. Turn off the computer.

5. Wait for 30 seconds.

6. Reconnect the power cord to the wireless router.

7. Wait for 30 seconds, or until the router is fully on and ready

8. Turn the computer back on.

9. Wait for the computer to reload

10. Reconnect the power cord to the rear of the printer.

11. Turn the printer back on.

Let’s try assigning a static IP to try and fix this issue. Follow the steps below:

• Obtain the IP address of the printer – You can touch the “wireless” icon on the printer control panel to get the IP address.
• Type the IP address on your web browser to obtain the printer EWS page on your computer.
• Go to "Network" tab - General - Select "Network protocols" - Select "Enable IPv4 only" (or similar) - Apply the settings.
• Go to the “Network” tab – Click on “Wireless (802.11) – Then click on “Network address (IPv4)
• Click on the radio button which says “Manual IP” and then click “Suggest a manual IP address” to give a manual IP address to your printer.
• Click on radio button which says “Manual DNS Server” and under manual preferred type 8.8.8.8 and under manual alternate type 8.8.4.4 (This is Google DNS server address)

Once done, reinstall the printer drivers. Follow the steps below:

• Unplug the USB cable from the printer and computer if present.
• Go to Control panel – Programs and feature – Select all the HP Envy printer entries and uninstall them.
• Restart your computer.
• Now click on http://ftp.hp.com/pub/softlib/software12/COL34882/lj-86469-4/CP1520series_n_full_Solution.exe to download and install the updated printer drivers.
• In the connection type window, select “Wireless” and follow the on-screen instructions to complete the installation.
