However, there are other probable causes for this message with an error 49 code to appear. There is a chance that it is related to the file that is being printed, or it could be due to a firmware problem. You must determine the cause of the problem and then fix the error to be able to make use of your printer again. This tutorial will guide you how to resolve printer error 49 on HP printers.The first step to fix Printer Error 49 is to “calibrate” the printer. This basically means that you use several inbuilt Windows features to not only make sure your computer recognizes the printer, but is also able to simulation software perform operations & print from it. To do this, you basically just need to turn off the printer, and then turn it back on again. After you’ve done that, test out the printer from another application, and if that works, you should look at what could be causing the problem in the other application you were using. If the printer doesn’t work on a different application, then you should “reinstall” the printer on your system by using the “Device Manager” to remove the device and then install it again.The second step to fixPrinter Error 49 is to use a “registry cleaner” program to scan through your PC and fix the various errors that your PC may have inside.
