I'm trying to figure out how map a function or sub that grabs a file from some directory 'C: Temp.pdf' and prints it to a designated printer (I will have to print to multiple printers). On top of that, I need to be able to tell the printer when it's time to print that it needs to staple the printout together when finished.
If you're printing from your Mac to a:. If your printer is connected to your Mac with a cable, disconnect the cable from your Mac. Turn off your printer. Your Mac automatically downloads the latest software for most printers as part of these updates, so it's best not to install software from the printer manufacturer. Reconnect your printer to your Mac, if applicable. Turn on your printer and wait for it to finish starting up. Choose Apple () menu System Preferences, then click Printers & Scanners.
Select your printer in the list of devices. If your printer doesn't appear in the list of devices in Printers & Scanners preferences, click at the bottom of the list, then choose the command to add a printer or scanner. The window that opens offers, such as by IP address: If you still can't print, and your printer is connected via Wi-Fi:. Restart your Wi-Fi router.
Then restart your printer. Move your printer closer to your Wi-Fi router. Update your printer and Wi-Fi router with the latest firmware from the manufacturer. If the issue continues on your Mac after, take these final steps to remove any currently installed printer drivers. These steps don't apply to.
From the menu bar in the Finder, choose Go Go to Folder. Type /Library/Printers/ and click Go. The Printers folder opens. Choose Edit Select All, which selects all items in the Printers folder. Choose File New Folder with Selection, which puts all of the selected items into a new folder named New Folder With Items. To save storage space, you can delete this folder. If the issue continues, contact the printer manufacturer for support. In corporate environments, DNS records can be configured to allow AirPrint-enabled printers to appear across other networks instead of just the network used by the device you're printing from.
You can also use in iOS to set up AirPrint printers. Firmware updates—such as for —update the software on the printer or router, not the software on your Mac or iOS device. If the latest firmware from the manufacturer is several years old, the manufacturer might have stopped supporting or updating your device. If so, you might need a more up-to-date printer or router.

As the title implies, today we will learn how to retrieve the local and the public IP address, as well as the MAC address of a computer using VBA. First of all, the definition of IP address according to is the following: “An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. Its role has been characterized as follows: A name indicates what we seek. An address indicates where it is.
A route indicates how to get there”. Public or external IP VS local or private IP A public/external IP address is any valid address, or number, that can be accessed over the Internet. Internet standards groups, such as the Network Information Center (NIC) or the Internet Assigned Numbers Authority (IANA), are the organizations responsible for registering IP ranges and assigning them to organizations, such as Internet Service Providers (ISPs). On the other hand, a local/private IP address is any number or address assigned to a device on a private TCP/IP Local Area Network that is accessible only within the Local Area Network. For a resource inside the Local Area Network to be accessible over the Internet, a device within the Local Area Network must be connected to the Internet with a public IP address, and the networking must be appropriately configured. MAC address (from ) “A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment.
MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model. MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware, such as the card's read-only memory or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address (BIA). It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. This can be contrasted to a programmed address, where the host device issues commands to the NIC to use an arbitrary address”.

Simplistic definitions When I am thinking of IP or MAC address, one simple term comes always to my mind: the national identity number – ID number. MAC address is the hardware’s ID number (usually the ID number of the network adapter), whereas IP address is the ID number of the computer over the local or the global network. As the ID number is used by the governments of many countries as a means of tracking their citizens, similarly the MAC and IP address are used over a local or global network (internet) in order to track down different computers or devices. Unfortunately there is no way to get programmatically the public/external IP of a computer without communicating to another computer over the internet.
Thus, the GetMyPublicIP function sends a request to and returns the response text. The GetMyLocalIP function on the other hand, uses WMI in order to get the IP addresses from the network adapters that have the property IPEnabled equal to true; then it returns the first non-empty IP. Finally, the GetMyMACAddress follows a similar approach with GetMyLocalIP function and returns the MAC address of the first adapter that has a non-empty IP.
