Though this is a step many users want to skip, the software is a vital part of the setup process. If you want to set up a USB printer on a HP Thin Client correctly the first time, you must use the software. Do not connect the printer until the software tells you to.
No matter what type of USB printer you purchase, the printer comes with software or the software is provided in the printer itself. If you do not have software, read the quick start manual provided with the printer to see if the drivers are installed automatically when you connect the printer.
Insert the software provided with the USB printer. If you do not have an external disk drive, install the software on the server the thin client connects to. The software will apply to all thin clients connected to your network. Follow the software prompts to install the necessary drivers to run your USB printer. If you can't use the software for any reasons, see your printer's manual for a link to download the software, which can be run from your desktop. Please note that you do not have to install the actual software to be able to print. For additional features, the software may be required. For instance, scanning in documents for editing may require the printer's scanning software. In many cases, the software bogs down your system. The only thing you need from the software disk is the drivers for the USB printer.
Sometimes, Windows will correctly recognize and install your USB printer drivers without the software. Though this method is not recommended, it is quicker when it works. If you try to set up a USB printer on a HP Thin Client this way and you find you can't print, right click My Computer, choose Manage, select Device Manager, select Printers, right click your printer and choose Uninstall. If the printer is visible in the Devices and Printers window, right click it and choose Uninstall. This will allow you to uninstall and reinstall you printer the correct way.
