Who cares? He's asking about the 4800 and it's about twice as fast as
the 7800.

No, Epson has a different "Professional Graphics" division ... here's
the link to their products ...
http://www.epson.com/cgi-bin/Store/WideFormat/pgindex.jsp?BV_UseBVCookie=yes
.... 4800 is on it, the 2400 isn't ...

Here's the link to the 2400 class products, which includes their
consumer-grade inkjets ...

> As for closer tolerences for the 4800 over the 2400, pure bs.

No, it's well known by Epson users that the Pro models are built better
and to tighter tolerances, with much smaller unit-to-unit variance ...
as one example, here's a quote from their FAQ on the Pro models from
the web site listed above for the Auto Head Alignment feature, which
isn't offered on the cheaper consumer models ...

"How accurate is the Auto Head Alignment and Cleaning Technology used
by the Epson Stylus Pro 4800, 7800, and 9800?

Very. In fact, although you can still perform these maintenance
procedures manually, you will probably never be able to beat the
accuracy of the whitebeam sensor technology inside the printer."

On the other hand... The 4800 comes with about $400 worth of ink right in
the box.
-This makes it's somewhat steep price not so outlandish after all...

Who said anything about non-Epson inks.

Measkekite strikes again.

Benwa, when I get the facts wrong I'm willing to eat my words and I got
this wrong, so I apologize ... the 4000 was almost twice as fast as the
7600 but Epson speeded up the 7800 considerably ... I found this
statement on the Epson release info for the 7800 ... "Utilizing our
latest high-performance print head technology, the Epson Stylus Pro
7800 is among the fastest print engines in the industry, while printing
twice as fast as our previous models."

And here are the actual speeds for the 4800 and 7800, which are pretty
similar for the same size prints ...
4800 speeds ...
• Fine — 720 dpi HS produces an 8" x 10" in 1:28, 11" x 14" in 2:27,
16" x 20" in 4:07
• SuperFine — 1440 dpi HS produces an 8" x 10" in 2:00, 11" x 14" in
3:25, 16" x 20" in 6:07
• SuperFine — 1440 dpi produces an 8" x 10" in 3:17, 11" x 14" in 5:35,
16" x 20" in 9:46
• SuperPhoto — 2880 dpi HS produces an 8" x 10" in 3:54, 11" x 14" in
6:35, 16" x 20" in 11:40
• SuperPhoto — 2880 dpi produces an 8" x 10" in 6:25, 11" x 14" in
10:55, 16" x 20" in 18:57.

7800 speeds ...
720 x 720 dpi - HS* produces a 16" x 20" in 4:20, 24" x 30" in 9:54
1440 x 720 dpi - HS* produces a 16" x 20" in 6:41, 24" x 30" in 14:18
2,880 x 1,440 dpi - HS* produces a 16" x 20" in 12:57, 24" x 30" in
26:54
*HS = High Speed Print Mode (Bi-directional Print Mode)

So for a HS 16x20 the 4800 takes 11:40 and the 7800 12:57, a lot faster
than the 7600 IIRC.

And, as long as we are printing corrections in this thread . . .

I said that the smallest size paper that the 4800 would handle was letter
size (8.5x11 in.). That is close but not quite correct. It will print on
paper that is as narrow as 8 in. wide. It will also handle paper,
lengthwise, that is 8 in. as well. So paper pre-cut to 8x10 would work, as
would 8x8 - if you could find that size. This all according to a call that
I made to Epson tech. support because of my own curiosity.
