How to Video Chat on Snapchat:   

Video chat is a great way to establish communication with friends and relatives. Although, we have other apps like Skype for the video chats we all like something extra. Isn't it??

When features like video and audio chats get added to our favourite apps like Snapchat, nothing can be happier than this.

But before we walk you through the steps to initiate a video chat, you need to know the requirements first. So here are the requirements for video chat on Snapchat!

#Requirements for Video Chat on Snapchat:

To start a video call on Snapchat, you need:

  • The first and major requirement is, of course, the Snapchat app. You need to have a Snapchat app installed on your phone. Without that, you can't have a video chat with anyone. Not only you, the person, with whom you want to have a video chat should also have a Snapchat app.
  • The second requirement, both of you need to be online at the moment of video chat. If the person with whom you want to talk isn't online, you can't video chat with them. But you can leave a video message if you want to!
  • Another thing, which you need to have on the compulsory basis is the front or rear camera. Without it, forget about the video calling.
  • Last but not least, the internet connection, of course! Without that, no chances of video calling.

So, once everything is up and ready, it's time to start video calling! Let's see how to do that.

How to Video Chat on Snapchat:

Video chatting on Snap is very easy. It's just similar to any other app. Below steps will tell you how to video chat On Snapchat. Believe me, it's as easy as ABC.

So shall we start with the guide??

Step 1. To start a video call with someone, first, you need to go through your contacts list. Now scroll up and down to find the friend you want to talk in the video call.

Now select the name of that person by tapping on its name. Once the name is selected, you will see a screen similar to the following screen.

Step 2. In the above screenshot, you can see there are multiple options there in the above image. Now there are no special methodology for video chatting or sending the normal text message or any snap.

If you want to send the text message, just type your message in the text field and send it to your friend by tapping the Send button. Or if you want to send any snap(Image) to your friend, just tap the first option, i.e image icon, browse the image from your mobile and send it up to your friend.

Similarly, if you want to call your friend with an audio call, simply tap the phone icon and for video call, you need to tap that camera icon. I've highlighted the camera icon in the below screenshot.

That's how we make a video call on Snapchat. If your friend is online, (S)he can receive the call. If the person to be video-called is not online, you get notified that the person is busy.

Step 3. When your friend is online, he/she will see a screen similar to the following screen.

There you can see the three options in the above screenshot. The first option is a big red cross, which is obviously to ignore the call. The middle option i.e Join is to accept the call. If your friends tap the Join option, he will come live with you on the screen.

The third option is the Watch. If your friend taps the Watch option, he will be able to hear and see you but you can't see the person. This option is good when your friend is angry, doesn't want to talk to you but want to see you apologising.

So to establish a two-sided video chat, the option to be used is Join. 

To disconnect the call, you need to tap the green camera icon   – ciao! If you touch this icon, you will get disconnected but you can still see and hear your friend until he also disconnected the call.

So this how-to video chat on snapchat!

But as I promised I'll tell you how to leave a video message when your friend is offline, here's how to do that.

Open the contact you want to leave a message for, tap and long press the grey camera icon, and record your message. As soon as you will leave the tap, the message will be released, just similar to the Whatsapp voice message.

If you are not happy with the recording, you can drag the recording to the big red cross option! Your message will be deleted.

So, that's it for the guide. You can drop the comment below, in the case of any doubt!

Installing a computer printer, basically, involves two steps. One, installing the software which allows your computer to communicate with the printer and the other one is establishing the connection.

The connection between a printer and the computer can be made via two mediums. One parallel and the other way is via using a USB cable. Most of the printers used in recent time mainly support USB.

If you have an old system, then you will have to use the parallel connections. Since this is the only options provided on old computers.

In today's article, we will let you know the complete step by step guide on how to install a printer for your computer,
So, let's not waste much time and get started with the guide How to install a printer for a computer. 

How to Install a Printer For Your Computer

The guide on how to install a printer contains all the steps that will help you to learn to install the printer. In this guide, we have provided almost all the steps with the screenshot.

But before following the steps, make sure all the cables are properly connected on both ends i.e., the computer and the printer. If it is so, move to the steps given below. And if the cables are not connected, then before following further steps, make sure you do connect them.

In the guide on how to install a printer on Windows, I will let you know all possible ways to install a printer on your computer. First, we will begin with the Printer Wizard. The steps are given below.

Step 1: first of all click on the start button displaying on the taskbar and go to the control panel.

Step 2: In the control panel, pick the category Printers and Other Hardware. Check out the below screenshot I have mentioned.

Step 3: As sooner you click on the Printers and Other Hardware option a new window will pop up. Here you will have to click on the Add a Printer option.

Step 4: When you click on the add a printer option, an Add Printer wizard will pop up. Click the Next button to enter the Local Printer wizard.

Step 5: In the next window, you will be provided with some options. There would be two radio buttons; you have to select the first option that is Local Printer attached to this computer.

Also, make sure the checkbox beneath this radio button i.e., Automatically Detect and Install my Plug and Play Printer is selected. If it is not, click on it. Once done, click Next.

Step 6: In the next step, you will see a New Printer Detection dialogue box along with the message Windows is searching for the new plug and play printers to install. 

If the wizard is unable to detect your printer in the New Printer Detection dialogue box, click Next to install the printer manually.

Step 7: When you click on the Next button, you will see a dialogue box I have mentioned below.

In the Use the Following Port drop-down menu, select the port for the printer to use. Once done, click Next.

LPT1 is recommended. But you can choose any if you want.

Step 8:  In the next window, you will have to select the manufacturer and the model of the printer from the Manufacturers and Printers section. Once done click on Next. 

And if you have Software Disk for the printer, then you will have to select the option Have Disk and insert the disk into your floppy or CD-ROM drive.

Step 9: After you click on the Next button, you will be asked to enter the name of the printer. You will see a dialogue box, similar to the image I have mentioned below.

In the image above, as you can see the name of the printer is highlighted. If you want to edit it or change it, simply remove the previous one and type the name you want. And try to keep the name as short as possible.

And if you want to keep the printer as default, then leave the Yes radio button selected just below the name.

Once done, click Next. 

Step 10: As sooner you click on Next, you will see a new printer sharing dialogue box. If you want to share your printer with other users, then select the radio button, Share name.

This is the name which appears in front of anyone when they select this printer for printing their documents. If you don't want to share the printer, keep the radio button Do not share this printer selected and click Next. 

Step 11: As sooner you click on the next button, you are done. You will see a dialogue box, the Print Test Page. If you want to print a test page from the newly installed printer, keep the radio button selected as yes. And click on Next.

And if you don't want to print a test page, select the radio button No, and then Next.

As sooner you click the Next button, you will see a completion wizard saying, completing the Add Printer Wizard. Simply click Finish.

And you are done!!

This is how to install a printer for your computer. This was the most useful way to install the printer. Another way to install a printer is by using the CD drive.

For this, you will have to establish all the connection as mentioned above and then Insert the CD that came with the printer.

If the CD doesn't start automatically, you will have to go to My computer and open the CD drive. Once done, open the setup.

In case, the CD is not working, or you are facing any issues with the above method I mentioned, you can download drivers as well and install them to the computer.

And you will be able to install the printer on your computer.

These were the three ways to install a printer. I hope you found the guide useful. In the case of any confusion, you can drop the comment below.

But, for those who don't know much about Netflix, let me give a quick introduction of Netflix to them.

What is Netflix?

Netflix is a subscription-based online video streaming service, which provides numerous television programs and films to subscribers. It works on the monthly disc-rental base structure.

Netflix is one of the very first Internet streaming media, which offers video streaming services to subscribers. To use Netflix, you need to have an Internet connection, Netflix application, and Netflix subscription. You can run Netflix on almost every device that has an Internet connection.

How To Use Netflix?

Netflix service is very convenient to use. All you have to do is to subscribe to Netflix, and you can enjoy video-streaming right after the subscription. The best part of Netflix subscription is it offers the free trial.

You can use Netflix by providing your billing information. Once your free subscription is over, Netflix starts charging you as per their plans.

How to cancel Netflix?

Though it offers free trial base service it starts charging you right after the trial period is over. If you like the services and want to continue with Netflix, no worries, let is be the way it is.

But, if you are not so happy with the services and want to quit Netflix, you have to cancel Netflix account.

How To Cancel a Netflix Account?

Now, you might be wondering how do I cancel Netflix? Or does Netflix cancel account? If this is so, don't bother yourself much. I'm here to solve your queries.

As I said above, Netflix is easy to deal with service. You can cancel Netflix subscription anytime and can re-subscribe to it without any hassle. Let's go with the step by step guide.

#1. To cancel your Netflix account, first, you need to log into your Netflix account or click here and enter your credentials.

#2. You can see your name along with your small-sized picture on the top right corner of the page. Hover your cursor there.

#3. A drop-down menu with a handful of options will appear. One of these options is Your Account. Click on that. See the above screenshot.

#4. Once you click on that, a new window will open up. There, in the My Account page, you can see all your membership and billing detail. Click on CANCEL MEMBERSHIP.

#5. Now, you need to confirm your cancellation by clicking on the Finish Cancellation button. But, before you do that, Netflix would provide you with the information like

  • When your current billing expires.
  • How long Netflix will save your viewing preferences
  • Notify you that if you decide to restart your membership in the future, the price for services may increase.

If you are sure about cancelling the subscription, click Finish Cancellation button and you are done. If you are wondering what ‘cancel my Netflix account will disallow me for the future subscription' you are very wrong. You can re-subscribe Netflix any moment you decide to.

All you need to do is log in again into your Netflix account and subscribe it.

If you have decided to cancel your Netflix account before the completion of the subscription month(for which you have already paid), don't worry, you can still use Netflix till your month is up.

But, make sure you return all your CDs you have been sent to your home by Netflix, else you'll be charged for them.

Moreover, Netflix also keeps a record of your viewing preferences for the next 10 months of your cancellation. So, if you re-subscribe them within that span of time, you'll be presented with all the shows and videos you left off and can continue watching them.

Hope all your doubts regarding how to cancel Netflix account is clear now. From now on, you don't have to be dependent on anyone asking how do you cancel Netflix or anything related to the streaming service!

You can now easily subscribe, unsubscribe and re-subscribe Netflix anytime you want.
