Hi Tom,
|
||
<BR>
|
||
<P><EM>> In case there is any interest... I have begun writing a backend for the
|
||
</EM><BR>
|
||
<EM>> Fujitsu fi-4750C scanner. (As this is a low-volume duplex "production" color
|
||
</EM><BR>
|
||
<EM>> scanner, I doubt there will be much interest.)
|
||
</EM><BR>
|
||
<P>Seems you're in a similar position to me. What do you think you'll do
|
||
<BR>
|
||
about the duplex thing? The suggestion to buffer one full page might
|
||
<BR>
|
||
be viable... although it's a shame, the Windows software that came
|
||
<BR>
|
||
with the scanner supported duplex out-of-the-box.
|
||
<BR>
|
||
<P><EM>> Which brings up a general question... Since most of the Fujitsu scanners
|
||
</EM><BR>
|
||
<EM>> that I have been exposed to in the past have very similar SCSI command sets,
|
||
</EM><BR>
|
||
<EM>> shouldn't we try to merge the functionality of the "sp15c", m3096g", "m3091"
|
||
</EM><BR>
|
||
<EM>> (re: post by Frederik Ramm), and whatever I produce for the "fi-4750C".
|
||
</EM><BR>
|
||
<P>I'd love to. But how do we handle things like different allowable
|
||
<BR>
|
||
resolutions, different maximum page sizes, and so on. It wouldn't be a
|
||
<BR>
|
||
problem to produce one source code file that, using "#ifdef"s, can
|
||
<BR>
|
||
produce three or four different drivers, but what options would we
|
||
<BR>
|
||
have if we were to try producing one single driver. An extra
|
||
<BR>
|
||
parameter, "--model", maybe - but how would we communicate to the SANE
|
||
<BR>
|
||
front-ends that certain settings e.g. of the "resolution" parameter
|
||
<BR>
|
||
are only available if the "model" parameter has been set to something
|
||
<BR>
|
||
specific? I doubt the current mechanism supports that.
|
||
<BR>
|
||
<P><EM>> With that in mind, I will 'try' to make my enhancements to a
|
||
</EM><BR>
|
||
<EM>> "m3096g" base keeping the original functionality unaffected.
|
||
</EM><BR>
|
||
<P>I won't bother since it's all a "draft" anyway. The main work will be
|
||
<BR>
|
||
figuring out *how* it works, and once I've got that, I'll be willing
|
||
<BR>
|
||
and able to build m3091 support into any clean, combined driver. I
|
||
<BR>
|
||
hope .-)
|
||
<BR>
|
||
<P>Bye
|
||
<BR>
|
||
Frederik
