Sorry James but I don't understand your point.
Computers store and manipulate data using a binary representation of numbers
sure but that doesn't mean they only handle powers of 2.
I need to correct something in my previous post. When I said dpm I actually
meant dot/mm and the figures I suggested were way to fine a resolution for a
typical laser or inkjet printer, it would be more like 10 dot/mm (rough
equivalent to 300 dpi). Whatever number is chosen it is purely to do with
the physical separation of the dots being produced on paper. There's no
reason why they have to be numbers like 8, 16, 32 etc if these are dot/mm.

Computer science is BINARY not decimal by nature, so
we're just NOT going to get nicely rounded decimal
numbers like many prefer on this board. Since a switch
is either "ON" or "OFF" it is only going to have two
possible numeric values 0 or 1. With the base-2
numbering system you get numbers like:
2^0 = 1
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
2^6 = 64
2^7 = 128
2^8 = 256
et cetera.
To show how little most people know about their
display device and just rely on what marketing people
tell them:
A lot of people know they have a 0.28 dot-pitch
monitor, and that screen resolution is 72 dpi ...but
have no idea what that means.
Hint: 0.28 mm / dot and 72 dot / in are both rounded
values of the same thing.
The modern trend is to have graphics in PIXELS, so
that it is device and output independent.
ALSO....high-resolution output:
After the number of dots/unit reaches a certain
threshold, the human eye can not tell the difference.
Printer manufacturers target this limit as a their
goal, not a rounded, rational number (regardless or
the measurement system).

hmm. A Microsoft invention eh? I didn't know Bill
Gates spoke with a lisp.
Anyway what we need now is to get rid of dpi in
favour of dpc, or maybe dpm,
for printing.
50 dpm, 100 dpm, etc would be a useful way to go.
