It's been difficult to get information on these two printers:
HP Paintjet II
Xerox 4020
Apparently, the Xerox costs more. Why? The proverbial question:
which is better (all reasons)?
Thanks,

Why? The proverbial question: >which is better (all reasons)? Both are very good. Red is a color unobtaible by both. The Xerox has a cyan cast to it's red, and the HP has an orange-red red. The Xerox does not have it's horizontal dot pitch equal to it's vertical dot pitch. I'd probably go for the HP; while at the same time sending a piece of email to nick flor at hp-sdd saying /* Sam Kinison mode ON */ HEY !

Nice, reasonably fast ( graphicdump fullpage about 5 min) and its NLQ font isn't too bad. Best of all they can be had for minimum $$$. .... got mine fer about $400 US at the time...

What's more, HP's Deskjet printer sells for about $1,000, around the price of a 24-wire dot-matrix printer. The US made printer uses a patented disposable thermal ink-jet print head to print twice the speed of a dot-matrix model - 240cps in draft and 120 in LQ. Each print head can do 400 pages before wearing out.... The Deskjet, which begins shipping this month, represents the first major technology advance in printers to come out of the U.S. in years. --------- -- Rich miner@ulowell.edu 617/452-5000x2693 ULowell CPE Imaging Research Lab

As you probably know there is a trade off in getting the colors 'correct' since inks have to be in the YMCB form and monitors are in the RGB form. I think that HP did a good job, their red seems pretty good to me. BTW, the Xerox_4020's dot density is the same in both the X and Y dimension. It is 120x120 dpi. If one turns on the 'special mode' then it is still 120x120 dpi BUT the printer outputs every line twice, moving the paper up 1/240th of an inch and spraying the dots 1/240th of an inch to the right. This (sort of) gives an effective resolution of 240x240 (but not really). It actually ends up producing much more vibrant colors although large areas of solid mixed colors (full red=magenta+cyan, green=yellow+cyan, and blue=magenta+cyan) tend to oversaturate the paper. It is quite an interesting effect. The HP_PaintJet's resolution is 180x180 dpi. Both are fine printers.

"thermal ink-jet"?
what's that? have they scrapped piezo-electric jets in favor of
ink rockets? or does "thermal" refer to how the ink is fused with
the paper?

It cools and hardens on the paper, voila! Not quite. Although the solid ink technology is indeed thermal :-), what is referred to by "thermal ink-jet" or tij is the method a spraying the ink. That is, there is a resistor near the nozzle which heats up and creats a bubble which forces a droplet of ink out the nozzle. This is all done with thin film technology (nozzle, resistor,etc), so the comonents are small, quick and accurate. Of course, the ink is quite special, because it can't dry up or it would clog the small nozzles. So a special paper is needed to absorb the ink base better than normal paper. Ethalyne Glycol is a popular base for these inks. -- Tony -- **************** Insert 'Standard' Disclaimer here: OOP ACK! ***************** * Tony Parkhurst --> hp-sdd!artecon!adp (or) hp-sdd!artecon!adp@nosc.ARPA * * "One lawyer can steal more than a hundred men with guns." -- The Godfather * *******************************************************************************

They are not piezo-electric or mechanical. Th'ink jets are much simpler than most other printing technologies. The ink is liquid at room temperature. charles@hp-pcd

I just want to point out that HP has a PLAIN PAPER inkjet printer called the DESKJET. They also have ink cartridges for the THINKJET and QUIETJET type printers that is designed to be used with PLAIN PAPER. (Black only) I don't know if there is a PLAIN PAPER cartridge for the PAINTJET. So -- You no longer MUST have special ink jet paper. -------- DaveS

The difference is output quality. From the advertisements, the DeskJet is just a higher res black only PaintJet (same thermal inkjet drop on demand blah blah blah). Oh, yes, and it retails for less than $1000 (probably $999). The DeskJet also *looks* kind of like a laser printer (the competition). I've seen the print quality first-hand; it's pretty good, but not quite as good as a laser (you have to squint do see the difference). John (* Due to Net recommendations, we purchased the PaintJet over the 4020. We're impressed, but HP is a little pricey. Will the 1.3 driver give us italics? *)

Speaking of printers... I just got back from NCGA'88 at the Anaheim
Convention Center (yes, CBM has a large "booth" there), and I saw the
most a m a z i n g new printer called the Pixelmaster from a company
named Howtek Inc.
21 Park Ave.
Hudson, NH 03051
603-882-5200
The Pixelmaster just debuted in January '88. It stands about 4' tall
and about 1' square, (picture a large floor-standing hifi speaker tower)
and retails in the neighborhood of $5000. They had it spitting out
Mac II images but they know about the Amiga, they have one, and they're
working on a driver for it... the printer emulates HP Laserjet so they
have to "colorize" the driver.
The printous are incredible. Hard to describe the clarity and the
quality, but I saw examples of everything from a Linda Evans portrait
to a bowl of cut flowers to letterhead and whether it was fonts (very
small/very large) or human fleshtones and the nuances of blonde hair,
the reproduction was exemplary. The printer uses plain paper (they
were running it with what looked like 20 pound bond). "Ink" comes
in the form of crayon-like sticks that you just drop into a slot.
They are melted and shot onto the paper, and the printer can spit out
a full page color pic in under 2 minutes. The finished printout has
a texture to it, you can run your fingers across the page and feel
the pixels :-)
Perhaps they'll send you a sample printout if you give them a jingle.
If you do, tell them you want them to support the Amiga (even though
they said already that they will but a little reinforcement can't hurt!).
disclaimer: I'm not on Howtek's payroll, but the Pixelmaster really
knocked me out. Just wanted yawl to know about it.

There was an appetite whetting "sub-article" on this printer in the Sept. 87 issue of Byte Magazine by Jane Tazelaar. It's at the end of the feature on color printing in general. Good issue (for a change). I was wondering if the beast would make it to the marketplace. Glad to hear it has, as the pics in the Byte article *do* look good. > The finished printout has > a texture to it, you can run your fingers across the page and feel > the pixels :-) Seems like you can *see* texture in the sky of the fishing village in the Byte article. May be the result of their color mixing/dithering algorithm, or be present in it original pic that was digitized. The parrot on the 2nd page shows this also, but to a lesser degree. > Perhaps they'll send you a sample printout if you give them a jingle. > If you do, tell them you want them to support the Amiga (even though > they said already that they will but a little reinforcement can't hurt!). Yes indeed! I hope they sell *lots* of them, so the price comes down just a little bit ... $5K, I can't afford, but at $1500 ... /kim -- UUCP: kim@amdahl.amdahl.com or: {sun,decwrl,hplabs,pyramid,ihnp4,uunet,oliveb,cbosgd,ames}!amdahl!kim DDD: 408-746-8462 USPS: Amdahl Corp.
