USFOS on linux

As a commercial (engineering) software, [USFOS][u] needs to be manually installed. I tried this today on [elementary OS][e], powered by frugal hardware, and USFOS runs just fine. At minimum, the following are needed:

1. usfos, xact binary, and usfos_etc files.
2. A valid license usfos.key file.
3. A computer with Linux 64-bit OS to run on.

As each binary needs to be separately downloaded from USFOS site, I’ve automated this via [wget][]. Here are the commands to run in a terminal:

Brother HL-L2321D as a network-enabled AirPrint printer

Brother HL-L2321D is a delightful bare bones printer. It's fast, prints duplex, and is lean on cartridge usage. HL-L2320D drivers are readily available for Windows 10 and MacOS, and installing this printer is a breeze.

Since connection to the printer is only via USB-A interface, it is not a network printer, since it has no LAN port and no built-in WiFi. For those that want their printers to work with their iOS devices, no AirPrint support out of the box either. But that said, making this printer accessible over network is pretty easy with any of the following two ways:

1. Connect it to a router that has a USB-A port.
2. Connect it to a Mac, PC, or a Raspberry Pi, and share this printer to be accessible for printing.

Setup on a Raspberry Pi
