The Office has a canon selphy cp900 photo printer. the IP address of the original wireless route settings is the same as that of the computer, so you can print it directly after installing the corresponding client software, later, I changed a wireless route, started DHCP, and assigned a private IP address 192.168.x.x, which is not a network segment with the computer. The client software prompts that the printer could not be found. Consider Windows Settings are in the registry, so start to find, 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M01/4D/67/wKioL1RQsSrjGoA8AAH0ZggK0tg332.jpg "Title =" QQ photo20129171521.jpg "alt =" wkiol1rqss?goa8aah0zggk0tg332.jpg "/>
Here, we can see that the port number is 8609, and the target address is a hexadecimal number 0xdf5a120a (3747222026). I want to know the rule, and finally I finally got it. The calculator converts the value.
650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/4D/68/wKiom1RQszjgIq2BAACpwEzDsoI114.jpg "Title =" QQ photo20129172413.jpg "alt =" wkiom1rqszjgiq2baacpwezdsoi114.jpg "/>
According to the IP address I set, it is reversely arranged in the IPv4 format 10.18.90.223, 1101 1111 is converted to 10, 223,0101 is 90, and so on.
Next, let's make it easy. We first retained the IP address obtained by cp900 In the DHCP settings of the wireless route to ensure that the IP address is the same every time, as shown in figure
650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M00/4D/68/wKioL1RQto2xyXXlAAEy_DqYlKE985.jpg "Title =" QQ photo20129173603.jpg "alt =" wkiol1rqto2xyxxlaaey_dqylke985.jpg "/>
Then add a 8609 port in the forwarding rule, 650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M01/4D/68/wKioL1RQtvPx-d4DAADWHegKjRM404.jpg "Title =" QQ photo20151129173635.jpg "alt =" wKioL1RQtvPx-d4DAADWHegKjRM404.jpg "/>
In this way, as long as the Internet IP address of the wireless route is set to the same network segment of the computer, for example, 10.18.90.223 in the registry of the Computer above, the client software will find the wireless route port 8609 for communication, as we have forwarded the request in advance, the request will be directly forwarded to the cp900 printer to implement the network printing function.
