Make sure you have the latest software

On your Mac, to find out which version of printer software you`re using, choose Apple menu > System Settings, then click Printers & Scanners in the sidebar. Click the printer in the Printers list on the right, then check the Driver version.

Restart or Reset Your Router

Shut down the router and turn it back on. Afterward, connect your iPhone and printer to the network and try printing a file wirelessly. If the AirPrint printer is still missing, or your iPhone keeps displaying a “No AirPrint Printers Found” error, reset the router and try again.

Update your devices

If you`re still seeing the “No AirPrint Printers Found” message, check if your Apple devices are running the latest operating system. If not, update them. The update will eliminate any issues related to the software that could be preventing you from connecting to the printer.

Tap Settings > Hardware > Printers > Create Printer Station. Enter a printer station name. Tap Printer then select printer. Click Connect AirPrint printer and choose your printer.
Open Terminal located in /Applications/Utilities/, enter ippfind , and then press Return. The first section is the name of your printer and the last section is the resource path. Enter the following command and the name of your printer to get the IP address: ping myprinter.
Try connecting the product to your router, access point, switch, or hub with another Ethernet cable. Try printing from another computer on the network to see if the problem persists. If network communication was interrupted while starting Epson Scan, exit Epson Scan, and restart it after a few seconds.
Update Drivers

Outdated or not updated drivers will not allow the printer to make a connection with your system. Thus, if you are thinking Why my Epson Printer is not connecting with Mac or IOS Device, then consider updating your printer drivers.

Start by checking your hardware

If you`re using a wired printer, make sure that the printer cable is properly connected from the printer to your PC. For wireless printers, check the wireless connection. Make sure the printer`s wireless option is turned on and available.

Open System Preferences, and select Printers & Scanners (Print & Scan) on your Mac. Select + to display the printer list. Select the printer`s name listed as Bonjour Multifunction. Select Secure AirPrint or AirPrint from Use.
Share all the printers that you would like to publish over AirPrint: System Preferences → Print & Scan → [select printer] → Share this printer on the network (to do this, Printer Sharing must first be enabled in the Sharing pane).
The most common issues that make a printer appear offline are old printer drivers, too many documents sent to the printer, network issues, loose cables, a paper jam or missing paper.
Almost all new printer models support AirPrint and you can use AirPrint on any Apple device, including your iPhone, iPad or Mac computer.
AirPrint works over Wi-Fi, so if your printer can`t be connected to over Wi-Fi like most of the best printers for Macs, you can be certain AirPrint isn`t enabled on your printer. You can still print from Apple devices to wired printers, of course. You just can`t do so with AirPrint.
Use AirPrint to print wirelessly to an AirPrint-enabled printer from apps such as Mail, Photos, and Safari. Many apps available on the App Store also support AirPrint. iPhone and the printer must be on the same Wi-Fi network.
An Apple AirPrint printer allows Apple mobile device and Mac users to print easily over WiFi, without the need for installing additional software. Only the sending device needs to be an Apple product for the AirPrint task to happen.
You may see a “printer offline” error if your computer can`t communicate with your printer. This can be caused by loose cable connections or an outdated printer driver or operating system.
If your wireless printer isn`t printing, be sure to check your settings. Make sure your Wi-Fi is enabled, and then check to be sure you`re connected to the correct Wi-Fi network. You can often check your connectivity by printing a network configuration sheet by selecting this option from the printer`s display menu.
