Hi Rene, hi Karl Heinz, I'm realy impressed by the quick and helpful answers, thank you very much!
I took a closer look at the Epson GT-30000 and the Avision @V5100. The Problem I have with the Avision: It has many features that I don't need like the standalone connection to a printer for copying, faxing etc. I can't use this features because I need cost-control, for example every page printed / copied or scanned must be send to a SAP backend and the print-quota of a user must be watched etc. Printing over IEEE 1284 does not sound like a professional solution where every second waiting for the paper to come out is money. I need a professional color- scanner/printer duo, which is fast in every operation and good in quality, too. The whole system will be controlable via a touchscreen-display-interface and the System should: Copy, Scan, Print, Scan to PDF/jpg, Burn to CD/DVD, send via eMail, save at webspace (FTP) and maybe more. All costs must costs must be cleared by the user. But the price of the Avision @V5100 is not higher than the GT-30000, so it is possible to hide the user-interface integrated in the Scanner and use it as a "scanner-only" peripheral. If the sane support is better (I think about the duplex unit) maybe this is a way. Maybe I've missed a relevant model, did you thought of a special Avision scanner Rene? The GT-30000 seems right: It is robust and offers just what I want. The Other thing is: Which interface to choose? I need to engineer the fastest solution possible, so I think SCSI is the fastest, am I right? Is the sane-backend so "abstract" that it can handle the scanner at USB/SCSI/FireWire or no matter what, or do I need special support for the interface? I'm currently just fetching informations, if I get the assignment I need to choose the right scanner for the job. Since I can program C, it should be possible for me to tune the backend if necessary but maybe it is much more efficient to sponsor somebody with expert knowledge to do that, because I'm neither a experienced sane-user nor sane-developer. And what I don't want is to buy a 5000ยค scanner and see that it don't work for me. I need non-interlaced mode for single-pass scanning, am I right? Is there any limit regarding speed or quality compared to the original windows driver assumed that the sane-driver is well adopted? Please tell me if I'm wrong at the devel-list. Should I switch elsewhere? Thank you again!
