Error 0x0000007e when connecting a network printer occurs quite often both in Windows 10 and Windows 7. In most cases this error occurs in configurations when the printer is directly connected to another Windows computer (print server) and shared for printing from other computers over the network.
In my case, the error appeared in the following configuration. There is a print server on the 32-bit version of Windows Server 2008 x86 with several shared HP (Hewlett-Packard) printers. If you try to connect any printer from this server to a computer with 64-bit clients (Windows 10 or Windows 7), the operating system successfully downloads the correct version of the HP printer driver from the print server, but fails to install it with the error 0x0000007e.
“Operation failed” with “error 0x0000007e”.
On Windows 10 computers, the printer connection error looks a little different:
Operation could not be completed (error 0x0000007e).The specified module could not be found.
Caution: This Solution require making changes to your Printer and Computer Settings and so may require technical expertise. It is advised to call our Printer Support Helpline on +1-877-717-6111 and talk to our Printer Support Expert who will guide you to fix the problems with your Printer.
However, there are no problems with connecting and installing shared network printers from the same print server from 32-bit Windows editions.
Error 0x0000007e appears only on 64-bit clients when trying to connect to a shared Hewlett Packard printer installed on a 32-bit print server (running on Windows Server 2003 x86 or Windows Server 2008 x86). Typically, the problem appears not with all HP printers, but only with those which are using the universal printer driver HP PCL (HP Universal Print driver).
What do you need to do to fix the error? First of all, you have to check that both a 32- and a 64-bit driver versions are installed on the print server. As you can see, x64 and x86 versions of HP Universal Printing PCL 6 driver are installed.
