HP7740 printing error after restart

[DisillusionedD]

Why do I have to power cycle the 7740 so often to make it print? Both the printer and my network are connected to the same wifi, I can see the printer in Devices, but (most times) when I try to print, I have to power cycle the printer. Is there any fix for this bug?

Hi @DisillusionedD,

I'd like to help with the printer offline issue.

Try the below suggestions-

Use HP Print and Scan Doctor

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues. 

For more information, go to https://support.hp.com/us-en/topic/printscandoctor

Set a manual IP-

To set a manual IP and try the steps below ( with control panel)

--->Touch on the wifi icon ((i)) on the printer, and take down the IP address 
--->Open a web browser (ex Chrome or Mozilla) and type in the printer's IP
--->then go to network ---> general ---> network protocols ---> select IPV4 only-->apply 
--->go to wireless ---> wireless 802.11---> select manual ip ---> apply
--->Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS.  
--->then go to settings on the main ews page --> power management ---> select sleep mode to max 15min

If the issue persists,

We would have to connect the printer to TCP/IP port- follow the below instructions-

 --->Touch on the wifi icon ((i)) on the printer, and take down the IP address 

a. Click Start/Devices and Printers.  Right-click on your HP Printer.  Select Printer Properties.  Select the Ports tab at the top.

b.    Select Add Port.  Select Standard TCP/IP Port.  Select New Port.

c.    Follow the Add Port Wizard.  Under Printer Name or IP Address, .  Example:  192.168.1.15.  The IP address will be copied under Port Name.  

d.    Select Next and Finish the Wizard.

Hope this helps! Keep me posted.
