Ha, great find! I'm disappointed that I didn't remember that my success simply owed to other LisaListers' helpfulness. Of course I should have suspected nothing else!

"James's change to my adapter --- moving Lisa pin 16 from PC pin 11 (\BUSY) to PC pin 10 (ACK) --- results in color printouts from the Lisa to the Canon printer! "

Alright, so I got my 3852 in today! Unfortunately it is the later revision with the two ROM chips. Initial playing around with it suggests it's not going to be as easy as whacking in a 1080A ROM and calling it good. With the IBM ROM in place (a 27C128), you can remove the OTP ROM and it'll still boot (I dunno if it'll print, but) however, once you slap in the 1080A ROM on either a 2764 or a 27128 (or a 27256), then the printer behaves as if there's no ROM installed - all status lights on.
Based on the pictures over on VCF, it looks like the 3852 has a lot more RAM onboard than the 1080A - I wonder if the start of ROM is in a different place on the 3852 than the 1080A?
On a more practical note, what's a good way to clean out the printhead lines? It looks like old ink dried up in the lines over the years. I'm also wondering what would be a good replacement foam for the black cartridge? I cleaned out mine but when it dried, the foam turned hard and shrunk.

You could use a kitchen sponge or some other absorbent pad.
The ink is water soluble. You could try pushing a lot of water through the lines if they're super gunked up. I had to do this on a slightly later Canon printer to get it going again that used a similar cartridge and flexible line setup (A BJ130e).

I think I need to figure out how to do this. I got the CMY lines working reliably but the K line won't print. If I watch the purge lines on the right side of the lever, the CMY lines are solid with no bubbles, but the K line only shoots out a little spurt of ink and then goes dry again. Interestingly the supply line going to the print head is solid with no bubbles as far as I can tell.
On another note, the OTP ROM is indeed the character ROM. Which makes me wonder if I can pull a Foone and make this printer print in Comic Sans... https://twitter.com/Foone/status/1347408722033745921/photo/1
