Windows 7 - splwow64.exe crashes when printing to network printer

I have Windows 7 RTM installed.
I am attempting to print from Office 2007 [i.e. excel, word - 32-bit] to a network printer: Xerox WC PE120 Series PCL 6. This printer has both the 32-bit drivers and 64-bit drivers installed. I have installed locally the 64-bit drivers from the Xerox website.

I can print a test page fine after installing the print drivers, however when i go to print from another application, such as word/excel. The print driver crashes with the following showing in the event viewer:

Attached is a screenshot of what happens in my local view also.

Please advise.

Found Solution:

It appears that starting with the RC release, MS did not include the full list of printer drivers on the install DVD. It also appears that when you tey to add a network printer, there is no simple way to find the missing drivers. Here's the solution (works every time on RC and RTM):

Even though your printer is not locally attached, first try to add it as a local printer. When you do this, and your printer is not in the selection list, use the option to search "windows update". Windows will go away for a while while it downloads a lot of missing drivers. You should now find your printer in the new improved list. Go ahead and install it.

If you need to, you can add as network now or leave local using the IP address.

Hi thedook, I've the same your problem (print driver host for 32 bit application has stopped working) with Windows 7 Professional 64 bit and, after installing the driver downloaded from the site of my printer without success, I've tried the trick you suggested, but among the drivers that Windows downloaded, there wasn't the one for my printer (Ricoh/Gestetner GX 3050N Aficio). These are the error messages that Windows returns to me:

As you can see, all of them refer to the same library file: GLS602P.DLL.

Any other suggestions?

Thank you very much.

I'm running 64bit Windows 7 and having the same issue. Trying to print causes splwow64.exe to crash:

My printer is a Dell 3000cn connected through my network.

I was using Excel and had just printed my un-saved master piece. When good old Micro$oft crashed it. in a panic I looked at what the OS was waiting on and found it was SPLWOW64. I stoped this from the task manager and I got my work back!!
Wow64 its great! Thanks guys!.
I am a developer and have to debug my code to get paid. I wish that was the same for the Windows7 team.

Thanks to thedook's post above. I added the printer as a local TCP/IP and specified the IP address of the printer, then when selecting drive, I hit Windows Update, and selected the closest matching model (there was not an exact match). Printing the test page worked fine, and subsequently printing from other applications now also works.
