Troubleshooting Printing Problems
Troubleshooting Printing Problems
When problems occur, you must be ready to troubleshoot those problems. Of course, when looking at what is causing the problem, you need to look at everything that can cause the problems. When it comes to printing, this includes
. The application attempting to print . The logical printer on the local computer . The network connection between the local computer and the print
server . The logical printer on the server . The network connection between the print server and the print device . The print device itself, including hardware, configuration, and status
The first step is to identify the scope of the failure; in other words, determine what is working and what is failing. For example, if a user can print from one application but not another on the same computer, the problem is most likely related to the application that is having problems printing. If the user can print to other printers with no problem, you should then try to print from another system in an attempt to duplicate the problem. If the problem occurs on multiple computers, you need to focus on the logical printer on the server or the print device. Of course, one place that might give you insight into some problems is the logs in the Event Viewer, specifically if the spooler has written any errors to the event logs.
You can confirm connectivity between the print client and the print server by opening the Printers and Faxes folder and double-clicking the printer to open the printer window. If the printer window opens and it shows documents in the print queue, the client is communicating with the print server. If you cannot open the printer window, the problem is with authentication, security permissions, or a network connectivity problem. You can test connectivity fur- ther by trying to ping the print server or by clicking the Start button, select- ing Search, and typing in \\printservername. Also, make sure that the printer has not been disabled or offline within Windows.
Printer in Windows
If you suspect that the print server cannot connect to the printer, you should first check to see if the print device is in operation: Make sure that the printer is on and online; make sure that it is connected to the server or network; and make sure that the printer is not showing any errors. Next, from the print server, make sure that the print server can access the print device. You can also make sure that the IP address on the logical printer port matches the address of the print device. You could test network connectivity by pinging the address of the print device.
If you suspect a problem with the print server itself, you need to make sure that the Print service and the remote procedure call (RPC) service is running. You might also try to restart the print service and make sure that you have sufficient disk space on the drive where the spool folder is located.
If you have trouble connecting to a printer on a Windows 7 computer, you can check the Advanced sharing settings and make sure the following settings are on:
. Network discovery . File and printer sharing . Sharing in the Public folder sharing section
You can also make sure that the Server service is running on the computer that is hosting the printer and that the workstation service is running on the client. Both of these are on by default for all Windows computers. If pages are only partially printed, check that there is sufficient memory on the printer to print the document. If text is missing, verify whether the missing text uses a font that is valid and installed. Of course, another reason might be that you need to replace the printer’s toner cartridge.
If your printed documents have garbled data or strange characters, you should verify that you have the correct print driver loaded for the printer. You might also consider reinstalling the drivers because they could be corrupt. Finally, check for bad cables or electromagnetic interference. See Table 11.2 for a list of common printing problems and how to fix them.
