Connection problems with officejet 7740

[TTinsley]

My printer is constantly losing wireless connection with my computer.  I have tried restarting my computer and printer and rebooting the modem.  I have deleted and re-entered the wireless settings.  I have removed the printer and reinstalled it.  I have tried updating the firmware.  I can get it working temporarily but then it will lose connection again.  Also, if one laptop has been using the printer.  Another laptop won't be able to print until they reinstall the printer.

I have HP Smart on my computer.  Right now it shows that the printer is connected but when I try to print a pdf using the app, the app shows it is ready but the printer spool indicates the printer is not connected.

HELP please.

Hi @TTinsley

Welcome to the HP Support Community. I'd be happy to assist you with the  "connectivity issue" issue. 

Try the steps below to resolve the issue -

Step1- Add the AirPrint printer to the Mac printer queue

Confirm you are using AirPrint by adding the printer in System Preferences.

1. Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

   Figure : Example of the Printers & Scanners window

   

2. Check if your printer name displays in the Printers list, and then do one of the following steps.

   • If your printer is listed, remove and re-add the printer to confirm it is set up for AirPrint. Click the printer name, click the minus sign  to delete the printer, click the plus sign , click Add Printer or Scanner, click the printer name and then continue to the next step.

   • If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, and then continue to the next step.

   • If your printer is not listed in the Add Printer or Scanner window, go to the Frequently asked questions in this document to resolve connection issues, try to add the printer again, and then continue to the next step.

3. Confirm AirPrint or Secure AirPrint displays in the Use or Print Using menu, and then click Add.

   Figure : AirPrint displays in the Use menu

   

4. Open a document or photo, click File, and then click Print.

Step 2-Assign a static IP address to the printer

1. Obtain the IP address of the printer – You can touch the “wireless” icon on the printer control panel to obtain the IP address.
2. Type the IP address at the top of your web browser to obtain the printer EWS page on your computer.
3. If you get any security notification, click on show details/advanced and 'proceed to this website'.
4. Go to "Network" tab - General - Select "Network protocols" - Select "Enable IPv4 only" (or similar) - Apply the settings.
5. Go to the “Network” tab – Click on “Wireless (802.11) – Then click on “Network address (IPv4)
6. 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.
7. Click on the 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)
