Some 64bit clients can add a network printer off a 32bit server, but one can't! Windows cannot connect to the printer. Operation failed with error 0x0000007e

kyates57 used Ask the Experts™
For some time now, I've been "experimenting" with various printer drivers for our London office setup. Our main print server is 32 bit, but even after attaching 64 bit print drivers, I get a Windows cannot connect to the printer. Operation failed with error 0x0000007e" message when a user on Windows 7 64 bit tries to connect. The funny thing is, I have two users who CAN attach to the printers without any issues using the HP LaserJet P2050 Series PCL6 driver, but one user who can't. All the users are on new Windows 7 machines.

The printers in question are a HP LaserJet P2015dn and a HP LaserJet P2055dn printer. Since the server is 32 bit, I am not able to extract the 64 bit drivers off the .exe file off HP's site, I get a message saying that it's not built for that platform. Does anyone have the 64 bit drivers for those printers?
I don't think it is a 32bit vs 64bit issue.   All of the windows workstations will be sending out streams of text commands to the server.  The likelier problem is connectivity or authentication.  Network printers sell well because we don't have to depend upon a server's set up to print.

This is the solution for going the opposite direction when you have a x64 server and you are having issues with getting the drivers to work with x86:

Ok, here is what we have had to do...Be patient...this is VERY VERY painful

You are going to have to get the model of the printer in question, HP 4250, then go to this site and locate it (this is the HP site that has nearly every printer driver that HP has out there):

2. Download the server 2008 x64 bit version of the driver and save it in a location for later retrieval
3. Go back to the site and go to same printer and download the Server 2003 x32 bit driver and save it in a folder for later retrieval

4. Log onto the Server 08 box with admin (domain admin) rights
5. Open up Printers through Control Panel
6. Click on "Server Properties" at the top of the page (if you dont see that then press ALT key -->File--Server Properties)
7. Go to "Drivers" tab
8. click "Add" -->"Next"-->make sure ONLY "x64" is checked-->"Next"-->"Have Disk"-->Drill down to where you placed the server 2008 x64 bit version of the driver
9. Do step #8 all over again except make sure you UN-CHECK "X64" and ONLY check "x86" and then do all the same steps except now find the driver you downloaded for the Server 2003 x86 (32 bit) driver
10. Now go through and add the printer. If you have already added it then just change the driver on the server to you x64 bit, click APPLY
11. Go to the "sharing" tab of that printer's properties --> Additional Drivers --> You should have both "yes" beside "x64" and x86"
12. Just share it like normal now. You have to have both IDENTICALLY MATCHING drivers.

NOW you should be able to add that printer to your Windows XP, Vista, or Windows 7 32 bit machine with no issues.

I can send screen shots of some things if that would help you out. Try this first. We do these ALLL the time and this is what we have to do.
I had the same error on a Win 7 64 bit Dell Optiplex 780. Other computers in the environment could print to this network printer without issue.

My solution was to restart the print spooler service on the PC. Then when I went back to the printer share it installed normally.
