LJ 127 will print wirelessly but not with UBS cable

[joebea3]

My LJ PRO 127 prints wirelessly but won't print if I use the UBS cable and turn off the wireless connection on my Mac.  The reason this is important is that I am taking my printer in my RV and I won't have a wireless connection so I want to be able to print with the UBS

Let me take a moment to thank you for posting on the HP Support Forums. 

I understand that you have an  HP LaserJet Pro MFP M127 printer and it prints fine on a wireless network. But does not print when connected via a USB connection. 

I would like to know the following information to assist you better:

• Do you receive an error message when the printer is connected via USB?

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Please reset the printing system in Mac. 

NOTE: Resetting the printing system removes all printers and scanners from the printers queue and clears all print jobs and print settings from the system, including printers and scanners that are not from HP. Resetting the printing system can be useful for troubleshooting printing problems, but you need to add all of your printers and scanners back to the list when you are finished. Resetting the printing system reset might resolve certain issues such as:

• Print jobs that are stuck in the queue

• An incomplete print driver installation

• Communication issues between the printer and the Mac

Post resetting the printing system, please download and install the printer drivers from this link. NOTE: Do not connect the USB cable unless prompted during the installation
.

I sincerely hope this fixes the issue. Let me know how it goes. Cheers!

Kazi, thank you for your suggestion.  I did not receive an error message but it turned out that I had not properly installed the software on my Mac.  I did not click that I wanted both wireless and USB printing when I originally installed the software.  And, when I reinstalled it yesterday, I still failed to catch that suble issue in the installation.  Today, with the help of a geek, he found my error and when we clicked that I wanted both, it worked that time.  Thank you again for the suggestion.
