The LaserJet 3600 printer is a 'host-based' printer.
As such, it doesn't understand any of the traditional Page Description Languages (PDLs) like PCL5, PCL6 or PostScript.
It uses a proprietary language (known, I think, as JetReady).
Most of the work of rendering is done on the host workstation, which rasterises each 'page' into one or more images, then compresses and encapsulates these images.
The printer firmware then just unencapsulates and uncompresses these images, and prints the resultant dots.
I've no idea whether or not iOS supports host-based printers.
