Canon CX Laserprinter. This used the PERQ raster operations hardware
to produce the bitmap for the printer and talked directly to the Canon
printer engine. The printer contains no formatter board.

As an aside, I converted an HP Laserjet 1 to the engine-only model to
use with my PERQ. I also wire-wrapped the prototype QIC02 controller
onto the prototyping area of an OIO board so I have ethernet,
laserprinter and tape in the machine.

I am told there was an official PERQ laser printer, just a rebadged
Canon CX-VDO. I've never seen one,
Thank you
I'm familiar with the Corona Data one; I bought one used for $500 when
Laserjets were >$2K, and used it as my primary printer for years.
I knew that the board that originally came with it is not very useful, but
there are other ways to drive it. I had an ABC DC37 switch for several
such boards, including the Eiconscript with HP-PCL and Postscript
emulation.
But, I didn't know that there was a popular Perq interface.
THAT makes it much more worthwhile!
IIRC, at one time TallTree (JLaser) sold a cheap reverisble modification
for using LaserJet as a CX-VDO, and a similar interface for SX.
Printer-Works used to provide a lot of information about them.
