Valid commands:
-f Enable Fast return from prints [1]
-s Query printer status
-m Query media information
-u Query user string
-U somestring Set user string to 'somestring'
[1] This terminates the backend as soon as the printer has acknowledged
the print job, without waiting for the print job to complete.
This can also be enabled by setting the 'FAST_RETURN' environment
variable. This is the default behavior when using this backend
with CUPS.
