You need to install the printer driver, and it's likely you'll find it here:

^]
Once you have installed and configured the driver for your printer you can get a handle to the printer using the
OpenPrinter[
^] function.
You can get a list of available printers using the
EnumPrinters[
^]
You can use the
WritePrinter[
^] function to send data directly to the printer, but it's usually easier to use
GDI[
^] or GDI+.
