Introduction

Thin clients are primarily designed:

•For use with terminal sessions using Microsoft Remote Desktop Protocol (RDP).

•For use with terminal sessions using Citrix Independent Computing Architecture (ICA).

•And/or as green screen terminal replacements.

Due to this design goal, HP thin clients provide limited out-of-the-box local printing support for the wide range of printers available today.

HP thin clients do not support document scanning devices, whether standalone or integrated into Multifunction or All-in-One Printers. This is not a limitation of the HP thin client, but a by-design function of the small-footprint software image installed on the thin client, which includes a minimum of operating system components. Thin clients are designed for session-oriented computing, not for the heavy local use that scanning requires. Typically, thin clients are connected to server sessions which access networked printers.

This document describes the new solution that enhances Thin Client local printing support through the use of HP Universal Print Driver for Thin Client add-on, from now on referred on this document as the “UPD for Thin Clients”. This add-on is based on the existing HP Universal Driver PCL5 (UPD, available at http:///www.hp.com/go/upd), and from this point forward referred to as “original UPD”. The original UPD has been fitted with some modifications to improve compatibility with the Microsoft® Windows® XP Embedded (XPe) or Microsoft® Windows® Embedded Standard 2009 (WES) environments and to better accommodate disk space limitations.

The UPD for Thin Clients differs from the original UPD in several aspects, of which the most important are as follow:

•The only language supported is English – there are currently no localized versions available

•No help files or user documentation included

•Status Notification Pop-up is turned into an optional component that can be removed when installing

•Plug-and-Play support for selected printers in the XPe or WES platforms

•Smaller installed disk space footprint

•Available only as a PCL5 driver at this time

Pre-requisites

•HP Thin Client or HP Mobile Thin Client running an XPe or WES image

•The installation procedure requires about 50MB of disk space on the system drive during installation, and 14MB for storing temporary files (Please check the environment variables %TEMP% and %TMP% in your system’s configuration; these point to the z: ramdrive in the factory image)

•After completing the installation and finishing NTFS compression, the installed driver will require from 12MB to 22MB of disk space in the system drive, depending on the install options.

•A supported HP printer.
