HP Cloud Print Driver for Windows Server 2003?

Question

Hello,
I have a unique (complicated) situation that I am trying to find a solution for.
Here is the deal,
My company is trying to set up a temporary remote branch location inside a building where we are unable to wire a network. Our solution is to use a wireless hotspot. Connected to this hotspot, we will have an iPad and an HP Laserjet M525.
The iPad will be connecting to our Citrix environment over VPN through Citrix Receiver to deliver a desktop interface to the iPad. This is needed to access a few applications that are used at the branch.
The problem now is printing, AirPrint wont work because the iPad is on VPN (and its at a windows interface, not the iPad's).
I had the idea of using the HP printers built in ePrint function to print, so I set that up. So now sending at email to [email protected] prints to the HP printer attached to the wireless hotspot.
Emaling to print works, but ideally, I would like this printer to show up in the Windows Devices and Printers, so that the user can just click print, choose the HP printer, and it will print, (with a delay obviously as its sending an email).
So I downloaded the HP ePrint Windows Driver, which has to be installed on the main Citrix servers so that the users session can grab the printer and use it, turns out the driver doesnt work on Windows Server 2003. 
My first attempt at a workaround was Google Cloud Print, which was fairly simple to connect to HP ePrint, but apparently the Google Cloud Print Driver doesnt work on Windows Server 2003 either.
Is there a version of the HP ePrint Driver out there that works on Windows Server 2003?
tldr:
I would like to print to a remote HP printer that is connected to a wifi hotspot from our internal network. I need whatever software I download to be compatible with Server 2003.
I understand this is over complicated but thanks for any input.

I believe I understand your issue.  You would like to use a print driver to print to your HP ePrint enabled printer from your apps that are hosted by Citrix server.  While I believe this makes perfect sense, HP does not have a print driver that officially supports MS TS or Citrix that also supports the ePrint Cloud path.  The reason for this is the ePrint windows driver is a "dynamic" print driver (similar to HP UPD dynamic mode) that handles multiple print paths (tcp/ip, wireless direct, cloud, etc) in a single driver instance by dynamically changing the port the print queue is bound to so the port is specific to the delivery path.  For example, if printing to a network printer it will use a MS Standard tcp/ip port.  If printing to the ePrint cloud a custom port is used, etc.  Well, if you have lots of Citrix users trying to print to a single print queue, but to different destinations, the users would be colliding with each other when they print by having the driver trying to change the print queue to different print ports at the same time.
What you could do is install an ePrint print queue on the citrix server if you can control the access to that queue to just your local branch users.  Also, if you only have on ePrint enabled printer the situation is even better as only one port will be needed by that queue.  You can find the ePrint software at www.hp.com/go/eprintsoftware   You might want to download the version of the driver that supports XP as Windows 2003 is very similar print system.
NOTE:  this is not a supported environment for this driver.  You would be using it without warrenty or support and no promises are being made here.
Good luck if you choose this path and please post back the results.  Thanks!
