c) After checking all of the physical components, you should try to resend the document Open the Print Manager by clicking the icon in the system tray/noti cation area In the Print Manager, select the failed print job by highlighting the job with Error in the Status column (see Figure 20-10) Select Documents | Restart If you are creating the printer problem, the printer icon in the system tray/noti cation area indicates that the print job has failed once again d) Highlight the document once again, and then select Documents | Cancel to delete the document If this were a real scenario, you would verify that the print drivers were installed and are the correct drivers for the operating system You would then perform Step 4 to see if the problem is related to the Print Spooler Step 4 If the print device is online and ready, there are no paper jams or mechanical errors, and restarting the document is of no help, you can check to see if the Print Spooler is stalled The Print Spooler is a holding area for print jobs and is especially important for network printers If the print device runs out of paper while printing a document, you may have to stop and start the Print Spooler before the print device will receive jobs again In 14, Working with the Command-Line Interface, you accomplished this task using the command line Now you will use the Services snap-in for the Microsoft Management Console (MMC) to do the same thing, only more quickly and in a GUI a) Launch the Services console by opening Administrative Tools in the Control Panel and then double-clicking Services b) Scroll down and highlight the Print Spooler Select Action | Properties You should see that the Print Spooler is started and running (see Figure 20-11) c) Click the Stop button The Print Spooler indicates that it has stopped d) Click the Start button The Print Spooler indicates that it has started e) Alternatively, you can highlight the Print Spooler and select Action | Restart You ll see a message stating that the Print Spooler is stopping, and then another message indicating that the Print Spooler is starting

Lab Analysis Test
Patrick and Erik are having a small disagreement Patrick says that printers can use a number of different interfaces, while Erik says that there are only two: parallel and USB Who is correct List the interfaces you are aware of and a typical use of each interface Theresa is using Windows XP and just purchased a printer from a friend When she installs it using the original driver CD that came with the printer, it won t install properly Why Danyelle has just joined a large organization as a level II tech and is tasked with the evaluation of all of the laser printers in use The business managers are concerned that all of the units will need to be replaced because of frequent paper jams and poor print quality Danyelle makes her recommendations, and is actually awarded a bonus for saving the company money What is her recommendation Brandon has sent a document to the printer, but the document never actually prints Where can Brandon check to see the status of the document Why are laser toner cartridges so expensive
