I have a raster only engine in the printer already. By that I mean a micro
that accepts pixel line images, and it's job is to print those in high
quality, as fast as possible.

I have another engine that is given the job of managing the other systems
in the printer, and converting "stuff" to pixel line images.
This design initially started as an ASCII text input printer, and has
"evolved".

I like the idea of just getting pre-rasterized data from the PC/PDA, that
certainly means less work for me.

I wonder about the complexity of this.
For example, I don't have "pages", my media comes on a roll.
HP-PCL is another one that's been discussed, and I understand there are
several variants on both of these systems.

If they would tell me, it would be easier to achieve. :)
