What should I do if the network printer is encrypted, the printer is displayed encrypted and cannot

HP network printers are encrypted by restricting IP addresses.

Visit. Background: HP LaserJet series of laser printers.

Connecting to a network through a print server makes the printer available to some people and not to those who are not authorized?

Solution: The solution that implements this feature.

Enter the IP address of the network printer in the browser, find the network-> control list, and find the access control list.

Generally as shown below);

Enter the IP address and subnet mask that you want to allow access to.

Then select the previous "check" and click Apply.

After setting the IP address that allows access, only the host with the IP address in the list can print point-to-point with the printer.

In fact, this control list is controlled by the subnet mask, for example, if the subnet mask above is entered, then only the host above can print, and no one else can print through IP. If the above subnet mask is entered , then the entire segment is .

can be printed. If you need to set up non-contiguous IP addresses that allow access, you can only set 10 users. Alternatively, use the subnet mask to set the range of CIDR blocks that are allowed to be accessed.

For example, the IP above is also , and setting the subnet mask to is equivalent to that the IP of this network segment can be printed. If the subnet mask is set to , it is equivalent to that the IP of this network segment can be printed. In this way, you can manually specify the IP that needs to be set to allow access to be contiguous IP, and then control the network segment of access through the subnet mask.

The above principle of subnet mask control is to replace the last bit of the subnet mask with an 8-bit binary number.

For example, the 248 above corresponds to 11111000 in binary numbers, and the number of digits corresponding to 0 is the number of its allowed access lists, because there are 8 binary numbers between 11111000 and 11111111, and these binary numbers are converted to decimal.

It's exactly a number between 248 and 255.

Some enterprise encryption products support network printing encryption, you can choose your own one.

The document encryption software such as Esaitong, IP-Guard, and Vertain all have print control functions, which support anti-leakage protection of printed files, including adding printing watermarks, recording printing content, printing date, printing host, printing page number, etc.

As for print encryption, it's not clear whether the encryption you want refers to the encryption of the network transmission process of the printed file.

You can use Haiyu to effectively solve problems, and the safety and after-sales service are very good.

Summary. 1. We know that there is no difference between PDF printing and Word file printing, so the first thing we need to consider is whether the PDF file is encrypted and cannot be printed. 2. If it is encrypted, then after we open the PDF file, we can't click on the print option, and the gray state is grayed out The PDF has been encrypted and cannot be printed.

3. If it can't be printed because of encryption, then here we go to the Internet to install a PDF restriction removal tool, and the encryption of the file can be unencrypted to print PDF can not be printed. 4. In addition, if you know PS, you can also use PS to make the PDF file into the first format, and then print, which is also a quick way to PDF has been encrypted and cannot be printed.

What should I do if the printer shows encryption and cannot be printed.

1. We know that there is no difference between PDF printing and Word file printing, so the first thing we need to consider is whether the PDF file is encrypted and cannot be printed. 2. If it is encrypted, then we can't click on the print option after opening the pdf file, and the gray state of the pdf has been encrypted and cannot be printed. 3. If it can't be printed because of encryption, then here we go to the Internet to install a PDF restriction removal tool, and the encryption of the file can be unencrypted to print PDF can not be printed.

4. In addition, if you know PS, you can also use PS to make the PDF file into a ** grid landing, and then file to imitate printing, which is also a quick way PDF has been encrypted and cannot be printed.

5. If the problem of PDF file encryption is ruled out, then we open the online neighbor, and click the "Printer and Fax" option in the window that opens, and the PDF is encrypted and cannot be printed. Rent Bi Chain 6、Finally,In the printer icon that clicks on the option,We right-click the printer icon and click on the "Properties" option,After entering the property window, click "Advanced Digital Pairing",Then click the "Print Defaults" button below to disadvantage that the PDF has been encrypted and cannot be printed。

Foxit Protection Master is a very popular software, the main function is to split multiple pages of large PDFs into multiple single-page small PDF formats, and you can set up multiple spikes of lead socks monitoring folders, automatic batch conversion.

First of all, open Foxit Protection Master, find "PDF Merge" in the toolbar, open the PDF file that cannot be printed, click "Open", and then click "Start" to merge. After waiting for the PDF file to be merged, we will save the merged new vibrasel file as a desktop, it is recommended to put it on the desktop, and then find the file on the desktop, and then we will go to the tomato to print this merged burning PDF file and find that it is no longer restricted by copyright and other passwords, and can be printed normally.

Now the office will use the shared printer, in order to for the security of the printer sharing, it is necessary to set a password, so how to set a password for the shared printer? Let's teach you how to encrypt a shared printer.

LAN Shared Printer Password Setting Method:

We need to find the folder option in the folder, find the simple file share in the pop-up dialog box, and then remove the checkmark at the back, and then click OK.

In the pop-up shared folder options, select the share as this checkbox, and below we will see the option of access type, in which we find the third option, which is to access this checkbox according to the password, and then enter and confirm the password according to the requirements and prompts.

We arrive at a different computer location and set up the computer to access the Sakura Bun. Here we talk about opening the Internet Neighbor, finding the name of the server in it, and then opening it and finding the shared printer.

Double-click on the printer and it will automatically search for the relevant driver, and at the end of the process, it will ask for the password and username for access. We enter the relevant password and click OK.
