| 548.1 | Some of it, at least, is a difference in devices | VAXUUM::DEVRIES | M.D. -- your Device Doctor | Tue Jun 23 1987 13:06 | 4 |
| I don't know if there have been design changes, but it is a fact
that LN03's tend to write darker and bolder than LN01's.

| 548.2 | difference in technology? | ATLAST::BOUKNIGHT | Everything has an outline | Tue Jun 23 1987 14:47 | 4 |
| Is it because the LN01 is a WRITE BLACK device and the LN03 is a
WRITE WHITE device?

| The old font environments for the LN01 used some "pseudo" sizes, so you
may well have noticed differences. BL8 contains the same typefaces
for text and headings, but in their true point sizes and weights.
Also, the monospaced typeface for BL8 (and V1.0) is completely
different from the LN01 monospace. I also agree with Mark that
LN03's tend to print darker and bolder than LN01's.

| Thanks for the explanation, Lee. I'll modify the local design file
to use different fontsizes to try to get back to what my users prefer!

Jack, were you being facetious by any chance?

I don't know for sure, but I suspect that it's simple a matter of
the engineering specs on pixel size. I've heard of write-white
devices that users thought were too light. Since "write-white"
carves out the blank parts of the page, larger pixels would decrease
the proportion of black on the page.
Then, too, the plain LN03 (as opposed to the LN03 PLUS) always writes
an even number of pixels in a continuous line, so it really would
produce more black than the pattern required (since the rounding
is in favor of the black). I understand that is not the case with
the LN03 PLUS, but it still looks nice and robust.
So there you have it, Jack. The ultimate in conjecture and supposition
to answer your technical question. Anything else? :-)

| 548.6 | a possible factor? | ATLAST::BOUKNIGHT | Everything has an outline | Tue Jun 30 1987 22:40 | 15 |
| no, I was not being facetious. Laser print engines fall into two
classes: WRITE BLACK and WRITE WHITE. The determination is based
on whether the "dots" in the picture written by the laser are
BLACK or WHITE in the picture. I believe its true that WRITE WHITE
laser engines are not quite as crisp and clean as WRITE BLACK laser
engines.
I believe the LN03 is a WRITE WHITE laser engine design. I don't
know what the LN01 is. I was asking to see if this was a factor
to consider.
(I'm sure someone from hardware will correct any incorrect information
in the above).
