Printers, the 2D kind are remarkable because they are
immune to Moore's law. This is because the EvilCorp
manufacturers aren't in the business of selling printers,
they like continuous income from overpriced ink cartridges
and obsolescence of the printer itself.
A quick look at any supplier
of printer consumables will
show you that there are THOUSANDS of slightly different
printers from each manufacturer, such a frenzied pace of
innovation must lead to a remarkable improvement in
performance? No, the 2 monochrome printers from about
2009 perform similarly to a recently bought model. In fact,
close inspection reveals that inside the plastic case with
pointless swoopy lines and tiltable screen, it looks the
same. The cartridges look very very similar, same
manufacturer... it would make everyone's life simpler if
they fit... no, some soulless engineer added a plastic lump
so it doesn't fit. You can cut it off, but they thoughtfully
added a chip... To protect me from the inferior print
performance I assume.
In an attempt to curtail the ranty tone, I'll summarize. The
company that makes a reliable printer with minimal
maintenance and running costs is negatively incentivized.
Instead, rebadging the same-ish hardware under a new
model number every year or two seems the only way to
The solution might be an open source hardware project.
Open source 3D printers exist, which demonstrates the
feasibility of 2D equivalent nicely, in fact it's more
achievable. Similar projects, like the modular mobile/cell
phone by "Phonebloks" are a bit silly. When hardware
changes as fast as smartphone hardware does, a fully
integrated design is likely to win. Printers, however, are
easy. No one cares if a printer takes up +/-39 cubic cm,
weighs +/-2000g, has a chrome bezel & a 4k UHD front
facing camera. Even the price isn't that important,
everyone I asked today ONLY knows you don't buy a cheap
all in one. It's there for the taking as long as it ABSOLUTELY
1. Prints. No 4min calibration and no, you're not getting a
new cyan cartridge, I want my boarding pass now.
2. Stops printing. Every printer I've ever used, when asked
to stop by software or hardware, doesn't. Stop now, not in
3 pages time. "Right, I'll yank your power cord, that'll teach
you.... wait, why does this printer take longer to boot than
my pc... and now its calibrating.."
3. Has very very much ink. I used to have a little
monochrome laser Samsung, it coped with all my
monochrome printing in my whole PhD on one cartridge.
Samsung don't make printers anymore because they clearly
violated the code. Anyhow, point is it would be trivial to
increase the toner 3-10 fold for a decade of printing.
4. Has a stable, reliable available driver. This should be
downloadable from the printer. It should be gettable via
USB from the printer, it should have "Driver available at
www.openprinterproject.com" printed on it. It should have
a list of drivers from other companies that will also work to
various levels. The driver code should be embossed into
the printer surface, or perhaps be derivable from basic
5. Hold a whole ream of paper. I have two printers, both
over a foot tall that don't. Why are they doing this? It also
takes guesswork on how many pages they CAN hold. That
should be written in the tray, the minimum # being "500".
On top of that basic platform people are free to add stuff.
A duplex module here, Wifi there, GPS for no reason
whatever. Also none of those yellow dots the government
uses. Maybe it could have laser/inkjet combo. Go wild.

||This is a very good idea, in every way. Do you think
the printer manufacturers would enthusiastically
support this initiative? I think itd be good if they
do. You should ask them.
||If it were open, youd have open firmware, open
drivers, and open hardware (printable, even). How
about the ink? Itd be good to have a kind of recipe
for suitable ink that any normal and resourceful
person could make on the kitchen worktop (to give
an idea of technological scale required, not that
you must make it there).
||Ink making cant be that complex, and printer ink
making cant be that complexer than the
aforementioned and unspecified ink. Perhaps itd
be nice to raise a small family of squid, destined to
become cartridge refills.
||Itd also be interesting to be able to make inkjet
nozzles at home, from insect parts.
||PS, if anyones getting an HP printer and they
intend to go for the Instant Ink scheme, contact
me and Ill give you a referral code, which gives
me a free month. Oh, it gives you a free month
||We should be able to do the print head positioning
- it's like a 3D printer. And it should be easy to get
ink for it - ink suppliers are happy to inter-
operate, it's the printer manufacturers who don't.
Paper sheet handling might be difficult - paper
rolls would be more similar to what 3D printers are
already handling, can you get standard paper in
rolls? But I think it's doable with a combination of
3D printed parts, simple motors, springs or
magnets, and simple rubber rollers, all of which
are probably easily available.
||It's the print head that's probably the hard part.
But I've heard that for some ink jets, the ink
cartridge includes the print head. So maybe you
could find some type of ink cartridge with a print
head that's been cloned by multiple third party ink
cartridge suppliers, and use that.
||If the project needs to be useful before the print
head part is ready, the paper handling part could
be used for multi-page scanning just by adding a
camera (either at the print head or viewing the
whole sheet at once) or smart-phone mount.
Maybe a multi-page laser cutter for paper would
also be useful. Or a multi-page pen-based plotter.
Or a multi-page pen-based plotter than uses
conductive ink pens (I think there are pens
available for that).
||I found and linked one. Looks like they managed to
do the print head. It didn't have paper handling to
do multiple pages by itself though.
||ETA: it had the paper taped down. I reckon a good
next step before handling multiple pages would be
having a roller to take in a sheet of paper, and
another to pull it out again. Then either improve it
so it can take just one sheet if you put several into
the rollers, or go straight to designing a large
paper tray and feeder (which needs to handle the
variable height and weight of the paper stack).
||It could be motorised to raise or lower the top of
the paper to the correct height. Or the mechanism
could sit on top of the paper, with enough of it's
weight counterbalanced to leave the correct
pressure between the rollers and the top sheet.
||If you base it on a 3D printer, you could have the
bottom of the paper stack on the level of the bed,
and the mechanism to get some paper from it at
the level of the print head.
||ETA: maybe easiest if the 3D printer had the bed
move up and down, rather than the print head.
There are some that do.
||What if the whole basis of a printer as we know it
were reparadigmed? A robot arm, a very very
detail oriented one, could administer over the top
of a ream of paper.
||It could pat it back into true
whenever the wind blew the top few out of true. It
could hold one of a choice of watercolour
paintbrushes, mixing the watercolours or gouache
and then precisely applying. This would take care
of the larger
flat areas and coarser tonal gradations, down to a
reasonable level of detail. It could then switch
media to pens, progressing down to a range of
black Rotring technical pens, for text and keylines.
||Then it could put the pen down, lift the sheet of
paper off the stack and place it in beside the stack
(or turn it over and do the other side).
||This is a problem particular to printers sold to the consumer market. Buyers of office printers for the corporate market don't stand for this nonsense and so office printers don't have this kind of obsolescence. For example, I bought a printer made for big corporations, the HP LaserJet 5M, which dates from the mid-1990's. It cost me £6 (including a full toner cartridge) from eBay, still works fine, and you can still buy 'compatible' (i.e. not HP) toner cartridges for it.
||Cheese, if you get finely ground cheese and use that
||Admittedly the aroma would fade over time, but old
print-outs could still be read by specially trained mice.
||Alternatively, we could all learn braille, end of ink
||Not a particularly new idea in terms of "Stop designing disposable technology".
||There are petitions out there to demand the "right to repair" which many vendors hinder by not opening up devices to third party repair. Apple is the obvious offender here, but it also applies to companies who use built in product obsolescence that a repair guy could resurrect for less that the cost of a courier, but again the parts aren't available.
||It's a sign of a disposable culture if repair shops be they shoes, TV's, computers etc have disappeared from the highstreet.
||Green disposal taxes etc could be used to offset the tax of repair shops. Repair shops are by definition Green entities - labour heavy and resource cheap.
||It seems a shame that this idea is limited to printers [ ].
||Demand the right to repair.
||Then demand devices that are cheaper to repair.
||Designs will then only change when the change to the cost of repair is warranted by what the change of the design offers.
||Market forces - demand the right to repair first.
||Im more in favourite of obsolescence, Id prefer
to have something last a fairly short time so that
when it expires I could get rid of it and get a more
up to date one. Theres nothing worse than having
stuff thats out of fashion.
