+### Adding a Printer
+
+A printer can be added using the webinterface.
+The webinterface is normally reachable on port 631.
+This process is guided and should be self-explanatory.
+However in some cases additional drivers have to be installed.
+For example Brother label printers of the ptouch series feature drivers that are available for most
+[Linux](/wiki/linux.md) distributions in a package named `printer-driver-ptouch`.
+When adding the printer a network address has to be given.
+For USB printers this can be done via the USB protocol.
+Continuing the example Brother label Printer QL-600 the connection `usb://Brother/QL-600` is
+sufficient.
+When using multiple printers the serial number can be given in addition to this.
+This is done by appending it the the mentioned connection string and will look like
+`usb://Brother/QL-600?serial=000J1Z140282`.
+The examples using the Brother printer are taken from a
