Web Services for Devices

Have you noticed that adding printers on a Windows machine has gotten to be so much easier because of plug-and-play and self-installation? You can connect the printer using a USB cable to one of the computer's USB port, wait a minute or two, and voila, the printer is ready to go. The same applies to adding a printer that is reachable over the network. You would simply click on the Add Printer button and Windows will detect the printer and add it automatically, even without connecting to the Internet to get the driver for that printer. When digging deeper into the magic under the hood, you will most likely see that Windows uses a Microsoft technology called WSD, one that has been adopted by many printer makers, to connect itself to these printers. This works well in most cases, but because Windows uses the generic driver for the device under WSD that should offer basic things like monochrome or color, double sided printing, and the number of pages to print, certain features on the printer may not be available to the computer users, namely things that are unique to the printer or only found in high-end printers. Among these are Secure Print, Store in Mailbox, Department ID Authentication, Booklet Folding, Saddle Stitching, and Hole Punch. Likewise, the scanner on multi-function printers, which are very popular these days, sometimes does not work but the printing portion of the device works just fine. The solution to this problem is simply to add the printer the old fashion way by assigning the printer a static network IP address and telling Windows the IP address of this printer. Once that connection is made, install the driver. Given the automatic nature of WSD, before trying out this manual process, you should go to the printer's management console to turn off WSD for that device. This is usually found under the Network Settings of the printer. With this feature off on the device, the device is not broadcasting itself to be captured by WSD on a Windows machine, forcing you to add the networked printer with its IP address. 

Because of the potential restrictions on advanced features caused by WSD, many high-end printers have WSD disabled by default. Xerox makes high end printers so to turn WSD on, you have to do this:
