When your printer and computer aren’t connected despite the printer being available on your business network or via a physical connection to the Mac, there are many troubleshooting techniques you may resort to for unearthing the reason behind the printer offline Mac issue. Once the Mac connections has been re-established and the proper installation of the printer software and drivers verified, you may go back to work or print business meeting documents, customer invoices, and employee notices about important future company events. When attempting the recovery process, kick-start the process with basic troubleshooting methods. If that doesn’t work and the printer hasn’t still risen from its grave, reset the printer system and add the hardware again.
Switch the printer on and ensure it’s all properly plugged with electricity flawlessly flowing through.
Inspect cables and reconnect or re-secure ones that are dangling loose.
Check if the printer has sufficient paper sheets to fulfill your print tasks. If no, add additional paper.
Inspect the dialog of the printer and see within the machine to see if there are any paper-jamming issues. If there is a jam, refer to the user manual for rectifying the problem.
Open the machine and inspect the cartridge ink levels if there is a window in the cartridge for viewing the levels of ink. Otherwise, inspect the machine software to determine there are any warnings of low ink presented. Most probably, you’ll have an “OK” button or something similar to press and dismiss the critical ink warnings and get back the printer online.
Ensure the computing machine trying to connect to the printer is on or part of the printer’s network, if your printer connects over to your company network.
Resetting and Reinstalling the System
Hit the Apple main menu, choose “System Preferences…” and launch the hardware section’s “Print & Scan” option.
Hit “Control” and click the printer list simultaneously. Hit the option “Reset Printing System” in the menu that pops up.
Use an Ethernet cable between the printer and router or attach a USB cable to connect the printing device to your company network. For direct or straight connections, directly connect the USB cable from the printing equipment to the computer.
Hit the main menu again and click “Software Update..” to launch any updates available for your system.
Click the menu and choose “System Preferences” from the menu that drops down. Hit the “Print & Scan” option.
Choose the button “+”. You would probably have to first select the Lock button and type in the admin credentials: username & password.
From the options that surface, choose “add scanner or printer.”
Choose your printers or printer from the options list and select “Add.” The operating system (Mac OS X) would then download and install the recent drivers and software for the printer.
Among the common problems that make printers go offline are outdated drivers, excessive documents, loose cables, network issues, and a missing or jammed paper. Also, the above step-by-step guide only applies to Mac OS. Other operating systems may see significant or slight variations in steps.
