If you send a print job and printer is not working, check the following things:
a) Is the printer turned on?
c) All the cable are in working condition.
d) There is no problem is power source.
If every thing is well, the next step is to check the print sever' print spooler status.
The print spooler is the hard disk space reserved for channeling print jobs from the PC to the printer. You can check the spooler status by two methods:
1. Click Start, Control Pannel, Printer and Faxes, and double click the printer icon.
2. Click the tiny printer icon in the system tray. This icon will be mostly there if print is failed to print.
The print spooler windows shows all the pending jobs. You can delete, start or pause jobs.
Print spoolers can overflow or become corrupt because of a lack of disk space or too many print jobs in the queue. The Printers window shows all the pending print jobs and enables you to delete, start, or pause jobs. The best answer is usually to delete the print jobs and try again. You might also run into a situation where the print jobs seem to spool, but then just vanish or “despool” as the jargon goes. The print spooler shows print jobs for a brief moment, but then nothing prints. Check the printer driver. An incorrect driver for the attached printer can cause this issue.
Incorrect Page Size
A print job that comes out sized incorrectly usually points to a user mistake in setting up the job. Check the Print dialog box for incorrect print parameters. Also check the Page Setup option in the relevant application. Make sure the user is setting up the page properly. If you know the page is set up correctly, recheck the printer drivers. If necessary, uninstall and reinstall the print drivers. If the problem persists, the printer’s print engine may be causing the trouble, but that is a possibility only when you continually get the same strangely sized printouts using a number of different applications.
Garbage Characters in Printout
Misaligned or garbage printouts invariably point to a corrupted or incorrect driver. Make sure you’re using the appropriate printer driver and then uninstall and reinstall the driver. If the problem persists, it’s possible that you’re asking the printer to do something it cannot do. For example, you might be printing to a PostScript printer with a PCL driver. Check the printer type to verify you haven’t installed the wrong type of driver for that printer. Try some of these diagnostic avenues:
• Make sure the printer cables are attached firmly and haven’t become loose.
• Turn off the power to the printer, and then turn it on again.
• To check the basic communication between the PC and the printer, try printing a plain text file—Notepad is excellent for that.
• Restart your computer. Many Windows and application problems can
be resolved simply by restarting your system.
• Reinstall your printer drivers. Drivers occasionally become corrupted and might need reinstalling.
• Check your resource settings for the parallel or USB port to verify no resource conflicts exist.
• Connect the printer to a different computer. If the printer continues producing garbage characters on the second computer, you know the problem lies within the printer.
• Try printing a smaller document. If you can print a smaller document, the problem may be insufficient memory in the printer. Insufficient memory can be remedied by adding more RAM to the printer.
Printer Not Responding
If the printer isn’t responding, check the easy things, first make sure the printer is turned on and the cables are securely and correctly attached. Make sure the printer is online. Make sure the application you’re printing from is sending the print job to the correct printer .Make sure you have the correct print driver installed for the printer. Try to print a test page. Try attaching the printer to a new computer. If nothing works, your printer might have to go to a printer repair facility.
