Win32 error code 2 when using prndrvr.vbs with latest HP P..

I have been using prndrvr.vbs and prnmgr.vbs to automate the
installation of any one of the hundreds of printers in our
organization. However recently I have been unable to use prndrvr.vbs
to install new HP print drivers.

Here is a typical command line that works fine to add a driver:
cscript c:\test\prndrvr.vbs -a -h "C:\Test\4100" -i
c:\test\4100\hp4100p5.inf -m "HP LaserJet 4100 PCL 5e"

HP's new drivers have a different .inf format and when I use the same
command line to install those new format drivers, I receive an error.
Here is a typical command line that would throw an error:
cscript c:\test\prndrvr.vbs -a -h "C:\Test\3800" -i
c:\test\3800\hp3800b.inf -m "HP Color LaserJet 3800 PCL 6"

The error I receive is as follows:
Unable to add printer driver HP LaserJet 3800 PCL 6 Win32 error code 2

With debug turned on:
Debug: In function ParseCommandLine
Debug: In function AddDriver
Unable to add printer driver HP Color LaserJet 3800 PCL 6 Win32 error
code 2

What do I mean by new format driver? Well, without posting the whole
driver .inf here is an example of a driver's .inf [Strings] section
that works fine:
[Strings]
Printer1="HP LaserJet 4100 PCL 5e"
DiskID1="HP LaserJet 4100 PCL 5e Disk 1"
DiskID2="HP LaserJet 4100 PCL 5e Disk 2"
DiskID3="HP LaserJet 4100 PCL 5e Disk 3"
HPDC_MONITOR="HP Master Monitor,HPBMMON.DLL"

Here is an example of a driver's .inf [Strings] section that doesn't
work:
[Strings]
PrinterClassName="Printers"
DiskID="HP Color LaserJet 3800 PCL Printer Driver Disk"
PRINT_PROCESSOR="HPZPP41w,hpzpp41w.DLL"
HP="HP"
HP_Mombi_Driver_Name="HP Color LaserJet 3800 PCL 6"
HP_Wizard_Driver_Name="HP Color LaserJet 3800 PCL6"

Any HP driver that has a driver who's .inf [Strings] section looks
similar to the first posting works fine. Any HP driver that has a
driver who's .inf [Strings] section looks similar to the second posting
failes with the "Win32 error code 2" error.

Anyone have any ideas? Anyone else run into this problem?
