Shared print out of order to find fault cause

With the continuous popularization of network applications, more and more organizations have established their own LAN networks. In order to make full use of the network's functions, more employees in the organization begin to use the network for sharing and sharing; Has also been widely used in the LAN network, this office mode can not only effectively save the unit's office costs, but also can fully improve the printing equipment and network equipment utilization efficiency. However, in the actual sharing of print, we often encounter some bizarre network failures, in the face of these failures, many people tend to be helpless, do not know how to deal with. Now, from the actual point of view, this article will contribute to the failure to resolve the problem that I have encountered in the past. I hope everyone can get help from the following content!

Shared printouts are out of order

There is a laser printer in the local area network, in order to save office costs and fully utilize the utilization of the printing equipment, the author specifically intends to connect the laser printer to a very high-performance computer system. The IP address used by this computer is 192.168.1.12, the host name is "hsyf", the computer is installed using the Windows Vista operating system, in this system environment, the author opened the network discovery function, while the laser printer connected to the local host is set to a shared state, and will The share name is “share”; all normal client systems in the local area network can normally access the shared printer and can also print document materials through the printer.

Recently, the author has been receiving calls for help from the employees of the unit and said that their client systems cannot print normally. The specific symptom is: After shutting down the host system “hsyf” and restarting each time, Other client systems on the LAN network can print one or two materials. However, when printing continues, the system will prompt an error and the network printer will not be found. In this error state, the user can be in the printer list window of the corresponding system. , find the target shared printer icon.

Locating fault location

At the beginning, I thought that the shared printers received more printing tasks at the same time, causing the shared printer to not respond to other printing tasks normally. So I rushed to the faulty printer site and disconnected the input power of the printer. Turn the printer on and let it reboot so that all print jobs stored in the printer's cache are freed. After the network printer restarted and stabilized, I tried to perform a network printer on my laptop. Sure enough, just as the employee described, just printed two items, and the system popped up the shared printing error message. It looks like this The phenomenon exists in every client system on the LAN.

Whether it will be a problem with the LAN network? Considering that all client systems in the LAN are sharing the same print, they all have encountered the same failure phenomenon. I also began to suspect that this kind of unstable printing is due to the instability of the network connection. Caused; think of this, I decided to test whether the local area network connection is normal; I in their own laptop, click "Start" / "Run" command, in the pop-up system running dialog box, enter the string command "Ping 192.168.1.12 -t", after clicking the Enter button, the author found that the ping command test operation is normal and the response speed is very rapid. There is no network delay and packet loss phenomenon. ; continue to use the ping command to test the switch address of the local area network, the author found that the test operation is also normal, which means that there is certainly no problem with the LAN network connection.

After excluding the network connection factor, the author began to suspect that the target shared printer's own working status may have problems. To confirm this, the author worked tirelessly to connect the laser printer to another client system, and at the same time re-set the laser printer to the shared state in the system; afterwards, the author tried to access the new location from his laptop. At the shared printer, it was found that the shared print was all normal. Later, the author was still a bit unsure, and shared print tests were performed on several other client systems on the LAN. The test results confirmed that the target shared printer was working properly, and that the malfunction of the shared print failure that occurred before was definitely due to "hsyf" caused by the host itself.

Finding the cause of the failure

After the above investigation, the author now basically believes that the fault location is on the “hsyf” host itself. Is there a problem with the operating system of the host or is there any problem with the settings related to network printing? After repeated weighing, the author decides that From the shared print settings began to check; speaking of it, I immediately in the "hsyf" host system, click "Start" / "Settings" / "Printer" option, from the pop-up system printer list window, find that Laser printer icon, right-click the printer icon, execute the "Properties" command from the pop-up shortcut menu, open the target printer's property settings dialog box, in which the author in turn checks the conventional, shared, advanced and other aspects Nothing suspicious was found.

Since there is no problem with the shared print settings, will it be a problem with the shared printer driver installed on the "hsyf" host system? Considering the frequent installation and uninstallation of applications, as well as the continuous detection of network viruses and In the process of Trojans, the shared print driver is likely to be mistakenly deleted, and some dynamic print program files are deleted, then the working state of the shared printer may naturally be significantly affected. In view of this, I decided to reinstall the driver of the laser printer again; in this operation, the author first opened the device manager window of the "hsyf" host system, found the target printer device, and right-clicked the device. Options, execute the "Uninstall" command from the popup shortcut menu to completely remove the old printer driver from the local system.
