We have a Sharp photocopier AR-286.
Both the scanner and the printer have separate ip addresses and are networked. The windows computers all access this printer and there is a windows driver which allows us to print using:
single sided, double sided, pamphlet (A5 on A4), and select A4 or A3.

I am successfully accessing the printer set up as:

lpd://192.168.0.15:515/

with the following driver:
Sharp AR-161 Foomatic/pxlmono (recommended), as there not a driver for the AR-286 listed.

Unfortunately, this driver does not let me select any of the options listed above, however I am pretty pleased I managed to get it working at all.

Does anyone know of a suitable linux driver, or any other way to get the above options?

Thanks in advance,
Ross
