Set Up a Printer: Wi-Fi Printing Without Frustration

With classic printing, the printer was connected directly to a computer by a cable. Anyone who wanted to print sent the job over this cable to the device. Wi-Fi printing dissolves this fixed connection: the printer no longer hangs on a single computer but signs in to the home Wi-Fi router – just like the smartphone, the tablet and the laptop. All devices are thus part of the same wireless network and can find each other. The print job then travels wirelessly from the phone or PC via the router to the printer.

The decisive idea here is the image of a shared room: all devices signed in to the same Wi-Fi are, so to speak, in the same room and can talk to each other. If the printer, on the other hand, is signed in to a different network – for example the guest Wi-Fi or a second wireless network of the router – it stands in a different room, and the smartphone cannot find it. This invisible difference is by far the most common cause when the printer seemingly fails to appear for no reason.

For the wireless path to work, the connection within the house also plays a role. If the printer stands far from the router or behind thick walls, the signal can be too weak, and jobs get stuck. Anyone already battling dead spots benefits from a well-covered home network – how to achieve that is described in detail in our article on stable Wi-Fi throughout the house. A reliable Wi-Fi is the foundation on which wireless printing first works without stress.

When Wi-Fi printing does not work, it is rarely the printer itself. As a rule, it is a few recurring points that resemble one another and are hard for non-experts to see through. We encounter these patterns on nearly every job and resolve them one after another. Anyone who knows them also understands why a clean first setup saves so much trouble later.

The classic case: the smartphone is on the home network, but during setup the printer accidentally signed in to the guest Wi-Fi, or there are two separate wireless networks and both devices sit in different ones. Since a guest Wi-Fi deliberately seals devices off from one another, the printer stays invisible. The solution is to sign both in to the same home network. Sounds simple, but in the menus of many routers and printers it is not always so – especially when the network names differ only by a single number.

Modern routers broadcast on two frequency bands: 2.4 GHz reaches further and penetrates walls better, 5 GHz is faster but shorter range. Many affordable Wi-Fi printers support only the 2.4 GHz band. If the printer is accidentally connected to the 5 GHz network – or cannot find it at all – the connection drops or never forms in the first place. During setup we therefore make sure the printer lands on the correct band and adjust the Wi-Fi settings if needed.

Many manufacturer apps push you toward creating an online account during setup and advertise ink or service subscriptions. For plain printing on the home network, such an account is in many cases not necessary at all. Anyone unfamiliar with the steps clicks through sign-up screens, leaves behind data and may sign up for a subscription they do not need. We set up the printer in a data-thrifty way, avoid unnecessary account requirements where possible and explain which app actually makes sense. Data thrift matters to us – more on this in our article on data privacy in the smart home.

Wireless printing shows its strength above all with the smartphone. Since 95 percent (Bitkom) of internet users go online on mobile, the phone has long been the most important device in everyday life for many. A photo of the grandchild, a travel confirmation, the recipe from an email or an important official letter – all of this can be printed straight from the phone, without the detour via the computer. Modern smartphones already bring a print function with the operating system, so often no additional app is needed at all. In the photo or document view, a tap on the share or menu symbol, then on print, and the printer appears in the list.

Scanning works the other way around: anyone who wants to digitize a paper document places it on the device's scanner and pulls the image as a file onto the phone or PC. A letter quickly becomes a PDF that can be sent by email or stored safely. This is handy for insurance papers, invoices or keepsakes. We set up the right function on request and show how scanning succeeds in everyday life.

For families in particular, wireless printing is a real relief: the children print homework from the tablet, the parents the school letter from the phone, and no one has to sit down at a specific computer first. How technology cleverly eases family everyday life is something we explore in our article on smart home for families. The Wi-Fi printer is often the first device that really gets used by everyone.

A printer is not a device you set up once and never look at again. For Wi-Fi printing to stay reliable in the long run, a few points belong to its care. On the computer, the right driver makes sure the operating system talks to the printer. Outdated or wrong drivers lead to error messages, missing functions or blank pages; keeping software up to date is one of the basic rules of secure IT (German Federal Office for Information Security). During setup we install the correct software and remove superfluous extra programs that many manufacturers bundle along.

The printer itself also occasionally receives updates to its internal software. These updates fix errors and close security gaps – an aspect that becomes increasingly important with connected devices. The German Federal Office for Information Security recommends keeping connected devices up to date and switching off functions that are no longer needed (German Federal Office for Information Security). We install available updates and switch off services you do not need, so the printer sits in the network securely and economically.

On top of this come the small, practical things: cleaning the print head, keeping an eye on ink levels, clearing paper jams correctly and re-establishing the connection after a router change. None of this is complicated, but much of it is unclear for beginners. Anyone with a fixed contact person does not have to deal with it themselves. For questions around the printer we are reachable by phone and come by again if needed – entirely without an anonymous waiting queue.
