Because Mac OS X supports all these technologies in its print system, you don’t have to worry about sending PostScript to a non-PostScript printer—even if the printer is an old dot matrix printer. For example, to print out the contents of a PostScript file named requirements.ps, you would use the command shown in Example 10-5.
If you are new to the Mac operating system, you may be wondering how to print a screen on a Mac. You may have already noticed the lack of a “Print Screen” button on the keyboard. This should not make you feel that the process is complex. By using keyboard shortcuts, you can print the screen on a Mac. You can capture specific windows or select an area to capture. What they call “Print Screen” in Windows is known as screenshots or screen capture in Mac. Depending on the screen capture action you need, there are several keyboard combinations to use.
You can pick one of the methods to capture screens and get used to it for everyday use. Let’s get started and see the 7 different ways to print screen on a Mac.
Method 1: Capture the entire screen
Step 1: press keys Command + Shift +3 simultaneously.
This will save a copy of your screen to the clipboard awaiting other actions. You can repeat the key combination without the “Command” key to save the screenshot as a PNG file on your desktop.
Method 2: Capture a selected area
Step 1: begin by pressing the key combination of Command + Shift + 4 simultaneously.
Step 2: the mouse pointer will turn into a crosshair. Use it to select the region you are interested in capturing.
Step 3: the spacebar will let you take a full-screen capture.
The selection will be copied to the clipboard. If you press the key combinations without the “Command” key, your selection will be saved to the desktop as a PNG file.
The selection will be copied to the clipboard. If you press the key combinations without the “Command” key, your selection will be saved to the desktop as a PNG file.
Method 3: Using the Touch Bar
With a MacBook Pro featuring a Touch Bar, you can use the Touch Bar to pick from “Selected Portion,” “Window,” or “Entire Screen” after you have simultaneously pressed the Command, Shift and 4 keys simultaneously. You can also take screenshots of the Touch Bar display using Shift + Command + 6 or touch the Screenshot Icon.
Method 4: Take screenshots with grab
If you have no time to memorize keyboard shortcuts, you can use Grab. This program is pre-installed on all Macs and will assist you in creating screenshots from the menu bar. Grab can let you take time-delayed screenshots in case you want to set the stage before you start.
Step 1: launch Grab from the utilities housed within the applications folder. Once launched, its icon will display in your dock. You can also pin this icon for quicker access later.
Step 2: you can either use the Capture menu system or the keyboard shortcuts detailed alongside the respective command.
Method 5: Timed screenshots with Grab
Grab gives you the option to capture screenshots on a Mac of the entire screen, an individual window, or a selection of the window. You can do this with a time delay of ten seconds. This gives you some time to properly position your mouse or open the right window before the shot is taken.
Begin by opening Grab, then select “Timed Screenshot” or press the shortcut Command + Shift + Z. Note that the mouse cursor will not show on the capture, but you can change that in the preferences.

Method 6: Using the preview
Preview is well known for its functions like opening photos, PDF, and other files on Mac. Printscreen on Mac is its other hidden feature you should know about. Open preview then highlights the file in the menu bar; the drop-down menu will give you the option to take the screenshot from where you can select “From window” or “From entire screen.”
Even though the keyboard shortcuts methods are faster, the Preview method allows you to choose where the screenshot ends. You can make edits of the screenshot using Preview before saving it with the desired file name and preferred location.

Method 7: Capture selection and save to clipboard
Printscreen on Mac, Command + Control + Shift + 4This method is more advanced but is very useful. It helps you PrintScreen on mac with options like a selected area, opened applications, menu bar, parts of a desktop, and anything else.
Option one: capture the selected area and save it to the clipboard. Press Command + Control + Shift + 4 then drag with the mouse to select and save to clipboard. This will change the mouse cursor to +with pixel coordinates. Once you click and drag selection as desired, it will save the area to the clipboard for use in other apps.
Option two: capture selection and save on desktop.
Use the Command + Shift + 4 keys simultaneously, then drag with the mouse to select the desired area. When you release the mouse button, the selected area will save on the desktop as a PNG file if not specified otherwise.

Conclusion
When you PrintScreen on a Mac, it will be sent to the clipboard or time-stamped, then save on the desktop as a PNG file depending on the method used. You do not need to memorize all these keyboard shortcuts.
Just one or two that are easiest for you, then practice on them, and you will find it very easy to print screen on a Mac.
Software This section of the manual is split into different sections for ease of use, one section covering Mac OS 10.8+ installations, and another covering Windows hosted print queueA print queue displays information about documents that are waiting to be printed, such as the printing status, document owner, and number of pages to print. You can use the print queue to view, pause, resume, restart, and cancel print jobs. setup. In most cases only one section applies on your network. As Mac systems have become more popular recently, many sites are opting for Mac print servers to support their Mac workstations. You can install PaperCut NG/MF directly on a Mac print serverA print server is a system responsible for hosting print queues and sharing printer resources to desktops. Users submit print jobs to a print server rather then directly to the printer itself. A print server can be a dedicated server but on many networks this server also performs other tasks, such as file serving, offering native, end-to-end Mac printing.
Terminology
Below is an overview of the common terminology.
Print queue: There are typically two ways of providing shared multi-system access to a printer:
- Configure each system to print directly to the device. The device needs to be networkable (e.g. have an Ethernet connection) and support multiple connections.
- Configure a shared print queue. In this setup, only one system connects directly to the device (e.g. a server) and in turn the device is shared on the network via a print queue. Other systems on the network print to the shared queue rather than directly to the device.
Option 2 is regarded as a better solution on multi-user networks as it provides a higher level of scalability, allows for centralized administration, and allows administrators to move or remap devices without needing to propagate changes to workstations. PaperCut NG/MF requires a shared print queue as it works by intercepting the jobs as they pass through the server's queue.
CUPSCommon User Printing System (CUPS) is a printing system for Unix operating systems that allows a computer to act as a print server. A computer running CUPS is a host that can accept print jobs from client computers, process them, and send them to the appropriate printer.: CUPS is the print queue system used by Mac. This is the same queue system used by many other UNIX based platforms including popular Linux distributions. Apple is a major supporter of CUPS.
IP PrintingIP Printing is a generic term used to describe a number of print protocols that are used to exchange print documents between a computer, a server queue, or a physical printer.: This is a generic term used to describe a number of print protocols that are used to exchange print documents between a computer, a server queue, or a physical printer. (Note: This term is also occasionally used incorrectly to describe the 'JetDirect' print protocol discussed below)
IPPThe Internet Printing Protocol (IPP) is an Internet protocol for communication between a print server and its clients. It allows clients to send one or more print jobs to the server and perform administration such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs. IPP can run locally or over the Internet. Unlike other printing protocols, IPP also supports access control, authentication, and encryption, making it a much more capable and secure printing mechanism than older ones.: This is an acronym for Internet Printing Protocol. This is the 'native' print protocol used by CUPS and the Mac. It's a modern protocol designed to work well on modern networks including local networks, or even over the internet or a WAN.
LPRThe Line Printer Remote protocol (LPR) is a network protocol for submitting print jobs to a remote printer. A server for the LPD/LPR protocol listens for requests on TCP port 515. A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character. An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue names may exist in one LPD server, with each queue having unique settings. The LPR software is installed on the client device.: LPR/LPDThe Line Printer Daemon protocol (LPD) is a network protocol for submitting print jobs to a remote printer. A server for the LPD/LPR protocol listens for requests on TCP port 515. A request begins with a byte containing the request code, followed by the arguments to the request, and is terminated by an ASCII LF character. An LPD printer is identified by the IP address of the server machine and the queue name on that machine. Many different queue names may exist in one LPD server, with each queue having unique settings. The LPD software is stored on the printer or print server. is the traditional UNIX based print protocol.
JetDirect/Socket: This is a very simple print protocol used to transmit print jobs to a physical printer on a TCP network. The printer accepts connections on port 9100. In Windows, this print protocol is often referred to as a Standard TCP/IP Port, and in some cases generally as IP Printing. Almost all network printers support this method.
BonjourBonjour is Apple's implementation of zero-configuration networking (zeroconf), a group of technologies that includes service discovery, address assignment, and hostname resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. Printing: This is not a print protocol, but instead is Apple’s method of publishing printers on a network so workstations can locate the device/queue.
Where possible PaperCut NG/MF works with all print protocols, however, we do recommend some over others. The following set up procedure highlights methods that have shown to work in most environments.
PaperCut’s recommended setup procedure is:
- Install the printers on the server using a compatible driver.
- Test printing from the server.
- Share your printers.
- Set up the workstations to connect to the server's shared print queues.
Optional hardware configuration
Some printer models support several of the connection methods listed above. If the printer offers the option to disable these protocols through their web administration page, you should turn off all except the connection method that you will use. This minimizes the chance of incorrect configuration, and the chance of a workstation user discovering the printer directly. Some printers also support access control via IP address. If this is available, consider setting access control so only the server IP can submit print jobs directly to the printer.

Handling unauthenticated systems (e.g. laptops)
Print queues in Mac OS X by default are unauthenticated. Authentication in an Open Directory environment is instead performed at the time of system login. Unauthenticated systems such as laptops fall outside this. The introduction of unauthenticated systems on your network mandates the need for an extra layer of authentication. To address this need, PaperCut offers two options:
- Popup authentication via the PaperCut client software.
- Authentication via a Release StationPrint Release Stations place a print job on hold and allow users to release it when required. Often a Release Station is a dedicated PC terminal located next to the printers, however, Release Stations can take other forms such as a web browser based interface. Some common examples where Release Stations can be used include secure printing, approved printing, and authentication. In a secure printing environment jobs are only printed when the user arrives at the print area and confirms his or her identity. This ensures the user is there to collect the job and other users can't 'accidentally' collect the document. In some organizations it may be appropriate to hold jobs until they are approved by selected individuals. A good example would be a teacher approving printing on an expensive color printer. Hold/Release queues can be used as a form of authentication in an unauthenticated environment. Users must authenticate prior to releasing their jobs allowing PaperCut NG to confirm their identity. or the web-based release interface (end user login > Jobs pending release).
It is your decision whether or not the authentication policy/procedure is to be applied to all systems on the network, or just 'untrusted' laptops.
Network-wide policy
This is the simplest solution and provides a consistent procedure and policy across all your users irrespective of their access method (such as via workstation or their own laptop). Select your authentication method and enable this option on ALL print queues. The set up procedure for both methods is summarized as follows:
Using popup authentication
- Select the Unauthenticated printer option on all printers. You can apply this to multiple printers via Copy settings from Printer to Printer.
- Ensure that all workstations have the PaperCut client software installed. This includes both authenticated lab systems and laptops. The PaperCut client must be running to be able to print successfully.
- Instruct users that they need to enter their username and password in the PaperCut client. You you can set PaperCut NG/MF to save the credentials for a defined period of time if required.
Using hold/release queue authentication
- Select the Enable the hold/release queue check box on all print queues. Jobs do not print until a user has authenticated and released the job.
- Set up Release Stations, or, on the Options tab in the PaperCut Admin web interface, select the Allow users to view held jobs check box.
- Instruct users on how to release their jobs. This procedure must be followed by all users.
Laptop only policy (advanced)
One problem with the network-wide policy discussed above is that the authentication method (e.g. client popup or hold/release queue) also applies to authenticated systems. In some ways this is a positive (i.e. provides a consistent policy), while in other ways it can be viewed as an unnecessary on trusted authenticated systems. This section discusses a solution appropriate for larger sites.
The solution is to set up two servers. One server hosts a set of queues for authenticated systems, while the other server provides queues for unauthenticated systems. Network router or firewall rules are used to ensure that only authenticated systems have access to the authenticated queues. Laptops systems must use the other queues. This is best done with partitioned IP address ranges and/or subnets. An experienced network administrator can assist with restricted server access by IP address.
Eliminating popup authentication via Mac Login Hook
You can use popup authenticationPopup authentication involves matching the source IP address of the print job with the user confirmed to be operating from the popup client IP address. Authentication is provided by the PaperCut NG client software in the form of a popup dialog requesting a username and password. To print with popup authentication the client software must be running on the workstations or laptops. to provide a secure environment. For example, there might be a mix of lab systems and unauthenticated laptops. The lab systems are managed and secured via authentication against a central user directory source, while the unmanaged systems (e.g. laptops) are limited to local user authentication only so user identity is indeterminate. Use popup authentication at the print queue level to provide an added level of user verification.
This is an advanced topic and is targeted at experienced Mac administrators with command-line knowledge. The double-authentication is eliminated by having the system login also perform the PaperCut log in via the system login hook. After the administrator has confirmed that the workstation is securely authenticating via a central directory service, they endorse the system by copying a shared secret file onto the workstation. To perform this endorsement, follow these steps:
Corposprint Mac Os X
- Setup the PaperCut client on the workstation and configure it to start via the login hook as explained in detail in Multi-User Install.
- Use a secure method (e.g. USB key or scp) to copy the file located on the PaperCut primary server at:[app-path]/server/data/pc-shared-secret.datto the workstation in either of the following locations:/etc/pc-shared-secret.dat or /Library/PCClient/pc-shared-secret.dat
- Set ownership and permissions on the file using the command line as follows:sudo chown root /etc/pc-shared-secret.dat sudo chmod 600 /etc/pc-shared-secret.dat
- Test login and verify that PaperCut popup authentication step has been eliminated by printing to an unauthenticated printer. Confirm that the job prints and logs as expected.
- Repeat the steps above for each trusted directory authenticated system (e.g. lab system) on the network, or use system imaging processes.
