Understanding Print Sharing Services
Printers and printing services are areas of Windows Server 2003 that haven’t changed very much in the migration from Windows 2000. Given that, let’s take a brief look at the relevant terminology associated with printing services and how Windows treats printing in general.
To Windows, a
printer is the machinery that

Some important points to consider:
It is possible and practical in some instances to have multiple logical printers for every physical printer. I cover some of the scenarios in which such a configuration would be useful in this section.
Conversely, you can associate one logical printer with multiple physical printers, creating a “printer cluster” of sorts. The technical term for this is a
printer pool, and it’s most commonly used when print jobs need to be directed to the first available printer. I also discuss that a bit later in this part of the chapter.
Different types of drivers are available for use in Windows Server 2003. Level 2 drivers are older drivers that were written for Windows NT which run in kernel mode, a function of the OS that makes the entire OS vulnerable to any instability on the part of the driver. Fortunately, ...
