Probably OT help with Epson scanner

I have an Epson V37 scanner and a laser printer. Epson has a utility to
make copies. Folks here helped me some time back roll back to an
earlier version of the copy routine which, in my opinion, worked far
better than the current one. But, one problem still prevails. It takes
forever to make a copy. It 1st scans (fast rough scan) the original to
size it up and then, eventually, scans at a slower rate to make the copy
and the computer (Epson Scan) sends it to the laser for printing. Does
anyone know of a utility that just plain scans 8.5 x 11 and prints it
fast? I've looked around and haven't found anything that looks promising.

Do you have the scan utility? If not it looks like you
can get it he

https://epson.com/Support/Scanners/P...SPT_B11B207201

The utility should be a TWAIN interface applet. In
that you should be able to set the default scan
resolution. Your scanner is designed for extremely
high quality image scanning. For copies of text
files 300 dpi should be plenty.

Another alternative, if you do a lot of this, might
be to just buy a low-end all-in-one.

A second option.... This may not be as useful because
it would require more steps on your part, but for what
it's worth, in case your Epson utility is limited:

http://www.jsware.net/jsware/scrfiles.php5#wiaed

It's an HTA utility based on Windows Image Acquisition
(WIA). In the past TWAIN was the method for talking
to scanners. Starting in XP, Microsoft came up with
WIA, which was meant to be an accessible interface
for scanners, cameras and image manipulation. If a
scanner supports WIA then that can be used instead
of TWAIN. The utility above just runs in an IE window,
which is what an HTA is -- a scripted webpage running
locally in IE as a program. But it can give you access
to the WIA interface.
The possible advantage would be that you
may be able to access settings the Epson utility doesn't
give you. The utility above, to the extent a scanner
provides, will show you your dpi options and let you
choose. The down side would be that you'd need to scan
to a file, open that in something like IrfanView, possibly
crop it, then print.

To use the above, just open the .hta file and
click the scanner icon. If your scanner is WIA-compatible
you should see a connection happen and then a window
will come up to choose your scan options.

Make sure the resolution is not set too high.

4800 DPI is too high for making paper copies of something.
Most printed materials you get in the mail, will consist
of halftone "dots", and scanning at higher than twice the
dot pitch is not supposed to improve the quality of the output.
(That's an application of the Nyquist sampling theorem.)

If you're handling photographic prints, the grain is
a lot smaller on stuff like that, and doesn't have nearly
the uniform pattern of halftone prints from magazines
or the like. You can crank the daylights out of the
resolution on those (your choice).

Maybe scanning at 150 DPI to 300 DPI is sufficient, depending on
the source material. For newsprint, the correct value is
even lower.

My scanner has a plugin that (partially) removes moire.
Moire caused by aliasing between the dot pitch and the
scanning resolution. And that's why I tend to "count the
dots per inch", before doing scans. So I don't select
too high a resolution, wasting storage space and speed.
I tell the plugin what dot frequency is involved, for
best results, and it takes care of the details.

My scanner never delivers data faster than 1MB/sec to 2MB/sec
or so. I expect yours is a lot better than mine. The speed
is limited by available light - the stepper has to stop moving
the carriage, the CCD or CMOS linear array "snaps a picture" and
the transport moves to the next row. The scanner tries to use
a bright light source, to reduce the exposure time after
the stepper stops to snap a row. But too much light, too aggressive
an approach, can damage sensitive (ancient) source materials.
That may be why they don't try a few million candle power
under the hood :-)

You can take snapshots of a printed page with a digital
camera, which results in a "scan" in a fraction of a second.
A 12 megapixel camera would be a good starting material.
The lens used is probably a limiting factor (barrel distortion,
chromatic aberration, all that photography jazz).

The 2nd scan to pick up the content of the document can probably be
altered to produce differing quality of saved image. Perhaps you have
it scanning at 2400 (perhaps needed for scanning photos) but 600 would
be sufficient for a text document, even 300 DPI would be enough for
readability with some loss of fine character attributes.

Oops, just read the other replies. Yep, the consensus is to use a
low[er] resolution for text-only documents when scanned in. Higher
resolution takes longer. There should be a setting in your scan
software for what resolution it uses. It may even have presets from
which you can select that already incorporate differing scan
resolutions.

Thanks for the replies, however, what I really wanted was some way to
stop it from scanning twice. I've had other scanners that just allow
the user to select the size of the object (like 8.5"x11") to be scanned
and it just does one scan at the final resolution. BTW, I have set the
scanner to 400dpi in the Epson Scan utility for other reasons. There
seems to be no place to change it in the Epson Copy utility. I assume
the Epson Copy utility either is preset in the program or it uses the
400dpi set in the Epson Scan utility.

EPSON Copy Utility 4.01, the CHM help file claims
the utility actually calls "EPSON Scan" to do the scanning
process. Either the scanning process has preferences, or
something else should be popping up.

Since "a picture of a kitten" shows in the CHM file, it
implies the people writing this utility, think they're making
copies of color images. So somehow, you have to make sure the
scanning portion of your Epson software, is configured for the
kind of item you're copying.

There are third-party utilities for this, but when
I saw the price of $129, I wasn't even remotely interested
in product capabilities.

Best guess,
Paul

Don't use the Copy utility. Just scan once, then print the scanned image.

Actually thought of that, but you have to launch the Epson Scan utility,
then draw the box as 8.5x11, then scan it, then open it, then print it,
then delete the file. Not very convenient. The lame copy utility is
actually faster and easier to launch and use. Next step, call Epson and
see what they say ... like that will go anywhere. But, thanks to all
for the good discussion. I'll report back if there is anything good to
report.

The forging boob has no clue how cancels in Usenet work, and that they
are not honored except by few Usenet providers and under very specific
conditions (none of which applies to the NNTP server that I or the
forger use).
