HP LaserJet M1530 MFP Silent Install

HP, as far as I'm concerned, has some of the most insane driver and software installs ever. They are right up next to Adobe, as far as craziness, some of the time.
At work, we just attempted to install the LJ M1530 multi-fuction printer. Of course there were issues as always with new devices like this in a proper enterprise environment. There are at least 5 workstations that the device driver needed to be loaded on. Once I hear that I wondered why I wasn't scripting the install.
So I downloaded the M1530's driver. The first thing I did was use 7-zip to unzip the contents of hp_M1530_MFP_full_Solution_usb_n_w.exe. I found the usual HP mess of install files with no useful instructions for a silent install.
I dug up what looked like the main install executable under the Installer directory and ran it with the /? argument.

hpbcsiInstaller.exe /?
The following text is what I got back

Not exactly the best to go on but at least it was something. After futzing with command line options for an afternoon and part of Monday morning I finally got it to work!
Here is the full command line that I used to get an almost (There was at least one cmd box that came up briefly during the install) silent install working.

hpbcsiInstaller.exe /UI=Silent /IPv4=xxx.xxx.xxx.xxx /AcceptEULA=True
If HP has documentation on this somewhere I wasn't able to find it. Hopefull this will help others out. We are getting more and more of the smaller MFP devices these days and automated installs for all the faxing and scanning software is critical when you have a large environment to deal with.
This sets everything up on my Windows 7 64-bit test workstations without a reboot.
