You should also look at the System log to see if the spooler has registered any error events, and, in the Printers And Faxes Folder, make sure that the printer is not in Offline mode. Attempt to print a job from an application on the print server. If you can print to the printer from the print server, the problem is not with the printer. If you cannot print to the printer from an application on the print server, create a new printer directed at the same port and attempt to print to the new printer. If that job succeeds, there is a prob lem in the configuration of the original logical printer. If that job is unsuccessful, there is a problem communicating with the printer, or with the hardware itself.

In this practice, you will redirect a printer. Redirecting a printer is useful in both proactive and reactive troubleshooting. If you are going to take a printer offline, you can redirect its logical printer(s) to another device that is compatible with the logical printer s driver. If a printer fails due to a paper jam or other error, you can also redirect the jobs that have already been sent to, and spooled by, the logical printer, so that users do not have to wait for the failed printer to be repaired, and do not have to resubmit their jobs. Note that additional troubleshooting practice is included in the Case Scenario Exer cise and Troubleshooting Lab sections of this chapter.

If a printing device fails, you can redirect print jobs to another printer. Assume you are printing to HPLJ8100. While your job is in the queue, a job ahead of yours encounters a paper jam. 1. Open the Printers And Faxes folder and ensure that HPLJ8100 is offline. If it is not, right-click the printer and choose Use Printer Offline. This will prevent generating errors because the printer is directed to a non-existent network port. 2. Open Notepad and enter text into the blank document. 3. Choose the Print command from the File menu and select HPLJ8100 as the printer. 4. In the Printers And Faxes folder, double-click HPLJ8100 to open its printer win dow. Confirm that your print job is in the queue. 5. From the Printer menu, choose Properties. 6. Click the Ports tab. 7. As it was configured in Lesson 1, the printer should use the network port IP_10.0.0.51.

8. Select the check box next to the port IP_10.0.0.52. 9. Click OK. You have now redirected the printer. All jobs in the queue, except any in-progress jobs, will be directed to the new port. The printer attached to the new port must be compatible with the driver used by this logical printer, because jobs have already been processed and spooled based on the existing driver.
Lesson Review
The following questions are intended to reinforce key information presented in this lesson. If you are unable to answer a question, review the lesson materials and try the question again. You can find answers to the questions in the Questions and Answers section at the end of this chapter. 1. A Windows 2003 Server is configured as a print server. In the middle of the workday, the printer fuse fails, and must be replaced. Users have already submitted jobs to the printer, which uses IP address 192.168.1.81. An identical printer uses address 192.168.1.217, and is supported by other logical printers on the server. What actions should you take so that users jobs can be printed without resubmission a. In the failed printer s Properties dialog box, select Enable Printer Pooling. b. At the command prompt, type Net Stop Spooler. c. At the command prompt, type Net Start Spooler. d. In the failed printer s Properties dialog box, select the port 192.168.1.217. e. In the failed printer s Properties dialog box, click Add Port. f. In the Printers And Faxes folder, right-click the failed printer and choose Use Offline. 2. You re setting up printing on a Windows Server 2003 computer. You attach a printer, configure a logical printer, and submit documents for printing, but the documents do not print completely and sometimes come out garbled. What is the most likely cause of the problem a. There s insufficient hard disk space for spooling. b. You re using an incorrect printer driver. c. The selected port is not correct. d. The device settings for the printer are using an incorrect font substitution.
