Harry,
I am so glad you disagree'd. But, you miss the point. Itis not 'skipping
dots'! It is how many dpi the printer does. The 'inch' is a fixed number.
On my old BrandX printers we did 90K dots/sq in. This produced a totally
black square 1in.x1in.
The way the printer 'IT' is how the IG 'draws' IT. I accept your pix of
two resolutions, but I do not agree. Our 1 inch/square printed 'targets'
just got lighter; nothing more. There wasnohorizontal/vertical
difference. Thank you for your () add, but the other axis is quite part
of this
whole equation. All your pix shows me is 'character spacing.' That is
totally IG control. Has little to do with resolution.
HTH,
Duncan

I really depends on how the printer deals with it.
If the printer does 600 vs 1200 DPI by "skipping" dots, then lower DPI
would save toner.
ie (linear only, not showing the other axis)
600 DPI "skipped"

600 DPI "Big"

1200 DPI may use a bit more or a bit less toner depending on the way
the printer renders it, but in most cases I would not expect a
significant change unless the printer was sill using 1200DPI dots, and
skipping pixels.

Thane,
There is a complex formula and special page image that most priter
companies use to help them compute (fabricate/lie) about their printed
pages/catridge. Please note that this business does NOT use 100%
coverage. I just do not know many folk that print fully black pages.
I have to claim age/time/forgetfulness for not recalling what the
'coverage' percentage was/is. But I do recall that there is a
specification
about this the all printer makers try to meet/exceed. And, alot of
this has do do with various makers 'image generators.'
Hi Duncan,
Yeah, I know about the page used (I've seen a copy from
Lexmark). I was just wondering if they are printing this page at
300dpi or 1200 dpi when they come up with the number of pages a
toner will print.
I was sitting down with graph paper trying to figure out the
dot coverage, so I appreciate your help. :)
