Printer going offline

[Rosm]

This is driving me crazy. My 7858 randomly goes off line. Usually it fixes itself if I shut down the computer and restart but this time it doesn't.

It makes no sense because I am able to scan and print from the HP Smart App. But I cannot print directly from other apps.

Why does this keep happening? I shouldn't have to reboot but I have not found a consistent way of turning it back on line. It was actually working for a while and now, since a recent Windows 10 update (which has caused me other problems), I'm again having issues.

Welcome to the HP support community.

I understand that you are getting printer offline error, follow these steps to fix the issue.

Use HP Print and Scan Doctor to fix connectivity and printing issues.

Download HP Print and Scan Doctor.

1. Run HPPSdr.exe from the download location on your computer.

2. Once HP Print and Scan Doctor opens, click Start, and then select your printer.

   • If your printer is not in the list, turn it off and on, and then click Retry.

   • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.

3. If a screen prompts you to turn on printer updates, click Yes.

4. If a screen prompts you to make your printer the default printer, click Yes.

5. Try to print.

Assign a manual IP address and that should fix the issue.

Find the printer IP address to assign it manually.

1. Load plain U.S. letter or A4 paper in the input tray.

2. On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .

3. Swipe up on the display, and then touch Reports.

4. Touch Network Configuration Page to print the page, which can be up to four pages long.

Setting a Static IP Address

Once you know your printer’s IP address from the page you printed, entering it is pretty easy. Here’s what you do:

1. Run your Web browser.
2. In the Web browser’s address bar, type the IP address of your printer and press Enter. Assuming you entered the right address, the HP printer control panel should appear.
3. Click the Networking tab.
4. Under Connections, click Wireless.
5. Under IP Address Configuration, click Manual IP.
6. Enter the IP address, subnet mask, and default gateway in the appropriate boxes.
7. Click Apply.
