Hello,
iam now doing a survey, on which end i should recommend a scanner for our aplication.

I have come through the forum and noticed that there were some suggestions to HP drivers. So i guess that not every vendor has a good twain drivers.

Have any of you some experiences with for example canon or fujitsu scanners? Is HP really that bad?

Can we say that some wendor writes better drivers than others?

Thanks.

if you provided a little more information - what kind of application, what kind of volume, what capabilities you're using,.. you might get a better response.

In my experience not all Hp drivers are bad I've had a lot of success with some of their scanners. In general I prefer Kodak scanners and personally think they make the best drivers or I should say their i30 - i65 devices - their newer devices I have no experience with. I've also recently had some real pleasant experiences with a fujitsu device. Canon I have no direct experience with but search the forum for Canon and you get a rather depressing experiences.

Hi Gabe, thanks for reply.

Scanner should be used for scanning documents in to our digital archive.
At first stage we need to scan our paper archive (20k+ of papers), so we can move it to backup location.
Second stage is daily use. Scanning icomming mail etc...

Some of the content we need to work with is on paper with low g/m^2 so iam afraid that we cant use Automatic Document Feeder only but also a the flatbelt.

I was thinking of using 200dpi grayscale images, there is also requirement on some speed but i think with theese settings (200 dpi grey) every scanner would be fast enough. Optionaly there might be some barcode recognition process from image (iam curently working on this)

I was looking at the Kodak devices esp i30 / i40 scanner but it lacks the flatbelt so i guess theese are out of game Sad

I was also looking at Fujitsu fi5015c which has flatbelt + document feeder but here iam afraid of not beeing able to controll ADF over twain.

Also i tried to work with older canon scanner and i was not very pleased becouse the twain driver was not able to controll the feeder (it doesnt return in supported caps).

Thanks.

The Fujitsu I have worked with (and heard about were) offered more support than you might think if you use customdsdata, especially if you don't mind hacking the customdsdata string.

Sure we can ...

My personal list :

1 - Kodak (all models)
2 - Inotec (all models)
3 - Panasonic (all models)
4 - Fujitsu (all models)
5 - HP (only high volume scanners)
6 - HP (low volume scanners)
7 - Canon 9080C (the worst implementation ever, mainly based on an ugly TWAIN hack to support ISIS from PixelTranslation)

This is from my own experience, so it may not be same compared to other developers on this forum. From 1 to 5 (included) I can work with them. Below 5 the nightmare begins ...

If you want to test the Kodak driver, you don't even need to buy a scanner, that's the major difference between Kodak and the other manufacturers ...
The TWAIN driver has a simulator mode for a range of scanners, so you can develop and integrate without the hardware in a first step. What you could develop for a high volume Kodak scanner should work also with other manufacturers scanners (that's what I did), with very few modifications.

Hi,
iam already using the i40 driver in simulation mode. Also Twain sample source, but the sample source has limited capabilities, kodak is much better.

You are trying to say that i can generaly switch any driver to simulation mode?

Have a good day.

No you can't, but with Kodak drivers I can simulate almost any kind of Kodak scanners in the same range, not just one model.
But more generally, using this simulator, you can assume (not at 100% of course) that your application is good enough to work with many scanners, not only Kodak.
Of course if you 'hardcode' some Kodak custom capabilities, you can't.
