Can you tell from this page whether my other printer is better?

http://support.hp.com/us-en/document/c00856588#AbT1

I don't see the dpi listed anywhere except for the scanner.

Wat the frig.

Did you get an email from me?  Now I am trying Thunderbird for nntp and 
I keep hitting "Reply" instead of "Followup".  But there's no mail in my 
outbox, so I don't know what happened.

[ yay, found the post that went out as email ]

Ha! Yes I was looking at the fax section (which is limited by the T4 and 
T30 ancient FAX specs)

So 1200x6000 is very decent, but you still have the "size of dot" issue.
One thing you can do is photo paper, which has less bleeding/absorbancy 
than regular paper. - Make sure to select the photo paper type driver as 
this prints a lot more slowly to minimize the amount of wet ink sitting 
on the paper.

A pro printing shop will have a loupe with a ruler in it so you can 
measure the size and bleed of dots from your paper.  Walmart (not a pro 
shop) will do an 8x10 for $2.89 .  Photo chemistry is going to give you 
the best true resolution. (Although I don't know the resolution of the 
Fuji gear at Walmart, in 2000 they used our Gretag[1] boxes which did 
true 4800x4800).

[1] I worked on the UI and drivers for the machine. I bowed to the 
superior intelligence of the Swiss engineers who used the width of 
molecules in their chemistry calculations.

One *BIG* limiting factor is the paper used.
Most paper will make the ink from an ink jet printer bleed and spread, 
possibly a lot. For the best quality, you need a coated, low capilarity, 
paper. That will make the ink take longer to dry, but prevent most 
spreading of the ink.

It's not such a problem with laser printer that use dry inks, but it 
still can affect the pring quality. For laser printers, the main 
limiting factor is the quality of the optics.

Here is the chromadepth scene again after changing the pattern from 
gradient to spherical. Unfortunately, I don't really sense any 3D 
effect. In fact the tree line in the distance is messed up. The leaves 
of the trees appear much closer than the trunks. I don't consider this 
experiment a success. :(

How do you reply? In my Thunderbird both Reply button in toolbar and
the Ctrl+R shortcut seem to default to "followup" for newsgroup posts.
Only "reply all" or "reply to sender only" include email address.

Also if you do accidentally send a mail via the newsgroup account it
is possible its outbox / sent folder is configured differently from the
email account. Possibly the mail ended up under "Local folders".

I have the same problem as Dick. You have to press the Followup button. 
I never tried the shortcuts though.

My 'Outbox'folder in Thunderbird is always empty. However, look into the 
'Sent/Local Folders' folder: there is where the messages go, from 
'Followup' as well as from 'reply'.

I did find the mail in Local Folders after I didn't need it.

In the message header pane, right-click -> Customize.  Remove the reply 
button. I never hit Reply anymore. ;)
