e-Print and printing from my iphone stopped working

[Craveking]

I have a Deskjet Plus 4155. Remote printing (e-Print) and printing from my iphone suddenly stopped working, I didn't change anything. It just stopped. I can print from my PC. All my settings are correct. EWS is telling me e-Print is enabled. The printer and iphone are on the same wireless network. It just stopped working.

Hi @Craveking,

Welcome to the HP Support Community

I understand you are facing an issue with your HP DeskJet Plus 4155 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Was there any update on your iPhone or on the printer recently?
• Which iOS version is running on your phone?
• Which application are you using on your phone to print?
• Have you tried printing normally from your phone?
• Do you get any error messages on the iPhone?

While you respond to that, Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle

Update the firmware 

• Click here to download and install the latest printer firmware from your product
• Click here to know different methods of updating printer firmware.
• Update software on iOS

Disable and Enable e-print from the EWS page once. Reference Document: HP Printers - Turn On Web Services

Print with AirPrint and check

1. Open the app that you want to print from.
2. To find the print option, tap the app’s share icon oror tap .
3. Scroll down and tap or Print. If you can’t find the print option, check the app’s User Guide or Help section. Not all apps support AirPrint.
4. Tap Select Printer and choose an AirPrint-enabled printer. 
5. Choose the number of copies or other options, like which pages you want to print.
6. Tap Print in the upper-right corner.

Hope this helps! Keep me posted.

To assist better:

• Was there any update on your iPhone or on the printer recently? iOS 15.6; Apple has frequent updates and I can't tell you if this problem was related to an iOS update.
• Which iOS version is running on your phone? iOS 15.6
• Which application are you using on your phone to print?  HP Smart
• Have you tried printing normally from your phone? Yes and I get asked for a user name (which is filled in as "guest" by default and password. I have never seen this log in screen before to access my printer
• Do you get any error messages on the iPhone? Yes. When using HP Smart to print, it sees the correct printer and then fails to print. I can scan from my iPhone but cannot print. This is very perplexing. The error message is error while printing. I get the option to reprint and same message again.

The firmware is correct. I do get a message that the app is seeing more than one router with the same wifi name but I only have one router which supports the typical two bandwidths, 2.4/5. I'll try the power drain and Airprint solutions and get back to you. Thanks.

This is the error message I get printing with HP Smart

[Craveking]

I also downloaded the latest firmware update and when the app asks me to check the box for my printer, it won't allow me to check the box. Unbelievably frustrating.

I have to tell you, this is completely unacceptable, I have spent at least 4 or 5 hours working on this issue. Nothing works. How can I scan from my iPhone but not print? Same app. That's the basic question.

I can print using AirPrint. I cannot print using the HP Smart App. The error I get says there was a problem during printing. Check the printer and try again. I’ve done all the power drain steps. The firmware was updated. I always have the latest iOS version. Why would it print with a random AirPrint app but not your own app?
