Technology is always changing, generally creating more efficient and effective processes. Devices connected to computers are also always developing and changing for the better. One of computer devices that has changed widely is wireless printers. Printers that used to use a lot of cables to connect to computers, now it can use wireless technology.
In this article we will discuss all about wireless printer and its DJID certification requirements in Indonesia.
What is wireless printers?
Wireless printers are a type of printer that can communicate via radio frequency transmission such as Bluetooth or Wifi technologies. Printers with Wifi technology usually operate in the frequency bands of 2.4 GHz and 5 GHz. The existence of this radio frequency technology allows users to print documents remotely so they can print from anywhere.
The most significant difference between wireless printers and regular printers is the presence of cables as a connector to computers. Regular printers still require a direct cable connection to computers. While wireless printers can connect computers via wireless technology.
How does it works?
Generally, printers are used by connecting them to a computer using some cables as the connectors. However, along with technological development, the process of printing documents with a printer can now be done wirelessly.
In addition, users can also make one wireless printer into a sharing printer. This condition allows several computers to connect to one printer on the same WLAN network. Here are the steps to connect a computer with a sharing printer via a Wifi network.
- Make sure the computer will be used to connect to the sharing printer is connected to the same Wifi network as another computer connected to the printer via cable.
- Open Windows Explorer on the computer that will be connected, then in the Windows Explorer address bar please type the IP address of another computer connected to the printer via cable.
- Then a list of printers that have been shared from that another computer with the IP address entered earlier will appear. Please select the printer to be used then click connect.
- If the computer has successfully connected to the Wifi sharing printer, then now it can be used to print documents.
The Benefits
The wireless feature on printers is one feature that already widely used on today’s printers. Efficiency is the main reason why this feature is highly equipped on printers. In addition to efficiency, there are several benefits provided when using wireless printers.
Simpler printing process
Wireless printers offer convenience in terms of connectivity and accessibility. Unlike regular printers that still require cables to print documents. To start printing with a wireless printer, users can simply connect their computer to the printer via a Wifi or Bluetooth connection.
Can be accessed by various types of devices
Not only computers and laptops, various types of gadgets can also be connected to wireless printers. Gadget devices such as tablets and smartphones that are equipped with Wifi connectivity features can also be used for the document printing process.
Do not require additional devices
A printer equipped with a wireless connection no longer needs to use an additional computer that is used as a server. So, wireless printers can be used with other devices as long as they are in the same network.
Save time and increase productivity
Unlike regular printers, wireless printers are equipped with wireless connections, simply connect your gadget to the printer to start printing. Working process becomes faster, hassle-free, and productivity will definitely increase.
DJID certification
As mentioned earlier that a modern printer can do Wifi or Bluetooth connectivity to connect with other devices. These technologies require strict monitoring from the authority to ensure there is no frequency interference or harm action during the operation.
That is why wireless printers need to be complied with technical standard in Indonesia before being used and marketed in Indonesia. The process of fulfilling the technical standards is carried out through DJID certification process. By processing DJID certification, it indicates that wireless printers with Wifi or Bluetooth features have complied with applicable technical standards and can be used and marketed legally in Indonesia.
Before processing DJID certification, it is necessary to perform RF, EMC, and Electrical safety tests for wireless printers because the RF, EMC, and Electrical safety test reports will be required during DJID submission process.
RF test
Generally, a wireless printer uses Wifi feature as main wireless function during its operations. Most wireless printers with Wifi feature can operate in frequency bands of 2.4 GHz and 5 GHz. The testing of Wifi is conducted based on the technical regulation of KEPMEN KOMDIGI No. 12 year 2025 and the required testing parameters as below.
| Frequency range | Classification of use | Output power | Channel bandwidth | Spurious emission |
| 2400 – 2483.5 MHZ | Access type 1 | < 27 dBm EIRP (500 mWatt) | < 40 MHz | ETSI EN 300 328 (min version 1.8.1) |
| 5150 – 5250 MHz | Access type 1 | < 23 dBm EIRP (200 mWatt) | < 80 MHz, < 160 MHz | ETSI EN 301 893 (min version 1.7.1) |
| 5250 – 5350 MHz | Access type 1 | < 23 dBm EIRP (200 mWatt) | < 80 MHz, < 160 MHz | ETSI EN 301 893 (min version 1.7.1) |
| 5725 – 5825 MHz | Access type 1 | < 23 dBm EIRP (200 mWatt) | < 80 MHz | ETSI EN 300 440 |
In addition to Wifi feature, some type of wireless printers such as a thermal printer also equipped with Bluetooth connectivity to supports it operations. The testing of Bluetooth is conducted based on the technical regulation of KEPMEN KOMINFO No. 260 year 2024 and below are the required testing parameters.
| Frequency band | Output power | Spurious emission | Testing method |
| 2400 – 2483.5 MHz | < 20 dBm EIRP | ETSI EN 300 328 | ETSI EN 300 328 |
In addition to Wifi and Bluetooth connectivity, some type of wireless printers such as multifunction printers also equipped with Fax function to support it operations.
EMC test
Since most of wireless printers are supplied by AC power, then EMC radiated and conducted emissions are required to be tested. The EMC testing process will be based on the international EMC standard of CISPR 32.
The testing of EMC radiated emission for wireless printers is carried out in the frequency range of 30 – 1000 MHz and 1000 – 6000 MHz. Meanwhile, the testing of EMC conducted emission is carried out at main terminal power of wireless printers and in the frequency range of 150 kHz – 30 MHz.
Electrical safety test
Since wireless printers are supplied by AC power, then electrical safety test is required to be tested. The testing process is performed based on IEC standards of IEC 60950. However, the required electrical safety parameters for DJID certification are only touch current and electrical strength.
The testing of touch current is carried out by attaching the test leads to particular parts of the wireless printers that possibly hold by hand. The results of touch current test should be less than 3.5 mA.
The testing of electrical strength is carried out by providing excess voltage to the wireless printers. The results of electrical strength test should be no disconnection when it is given a voltage of 1500V – 3000V.
