Docs for the Apple Daisy Wheel Printer

Not attached, but rather at this link: https://lisaem.sunder.net/adwp.tar.xz are 3 Apple Daisywheel Printer documents collected from various places on the internet. This includes the user guide, a quick reference, and a brochure I've found on archive.org.
For some reason, attaching this doc here proved problematic, even after increasing the attachment size limits well past the 32MB, not sure why.

I had meant to post this up earlier, but other things got in the way. At some point circa LisaEm 2.0, I'll likely add emulation for this printer, but will be low priority.

Of the 3 docs included, the most interesting is the quick reference which contains the printer's ESC codes that allows fine spacing for drawing graphics. However, this PDF is nonstandard in size and printing it will produce very fine mouse print which will require a magnifying lens unless you've got really great vision. If you happen to have a full reference manual for it, please share that manual.

You can see a demo of a Lisa printing graphics to this printer here: https://www.youtube.com/watch?v=tkGigZrVMbE (this our very own compu_85 ofc).

I pinged him a few weeks ago about his video and this printer, and learned a few things about this unique printer such as it's proprietary wheel size.

It turns out that this printer is both rare and unique. The wheel size it uses is specific to this printer and incompatible with standard daisywheels. This provides extra characters that the smaller ones do not at the cost of compatibility, and now add an extra feature of being unobtainium.
In terms of emulation, as long as I get the ESC code spacing correctly, I suppose I can use whatever form of courier font comes with the host OS and that should be "good enough", though perhaps not as authentic, so getting hires scans of full font printouts from the wheels will be useful for the emulation.

The printer was made by Qume - I suspect the fonts are the same as normal Qume printers, just with more characters.

Attached are some sample prints.

The attached photo was the result of trying the Courier wheel :/

This reference card also lists the characters: https://www.apple.asimov.net/documentation/hardware/printers/Apple%20Daisy%20Wheel%20Printer%20Reference%20Card.pdf

Thanks, yeah, they're not all that great in the reference card, some of them have circles around them and I wasn't sure if they're exactly the same as the wheels or somehow different, etc. Many thanks for the actual real samples, and thanks for finding the original link. I had downloaded that and forgotten from where.

One thing I just noticed: The full stop / period character is different than the "single pin" character, which is metal reinforced.

I took some high resolution pictures of the wheels, you can get them here:

There's also a picture of a standard Qume / Diablo 96 character wheel. Getting good pictures of these is difficult, shadows have to show the characters. If it will help I can take some more pictures with alternate lighting. The Qume 130 character wheel has some differences in the "extra chars" section compared to the Apple wheels!

Thanks,

Also, here's an article talking about the variations in print wheels https://books.google.com/books?id=hcHq9kHRifYC&lpg=PA297&dq=qume%20daisy%20wheel%20130&pg=PA289#v=onepage&q=qume%20daisy%20wheel%20130&f=false .

Wow, thanks for the trip down memory lane, was fun reading this issue of PC Magazine. So many computer problems back then that have similar solutions today - memory, disk space, data loss and backups. It's interesting to see so much software that's just gone the way of the dodo. Best part was seeing ads for DS/DD floppies and Unix (venix?), and turbo pascal "now with windowing, just send in your master with a check for $29.95" - that 132x44 video card vs the multigraph CGA (or was it almost EGA?) card reminds me of how nvidia is now putting out new graphics cards, and their ads for them.

Looking at the exponential improvement since 1984 it's weird to see how much is still the same and how much would be totally alien to me looking at today from the 1984 point of view. Wonder how much more amazing things will be in another 36 years from now.
