[First of all. The DNS setup for mostang.com seems seriously broken.<br>
|
|
I'm mailing this message by doing a telnet by hand to the SMTP port on<br>
|
|
24.1.65.179. It seems as if the name servers for mostang.com (which<br>
|
|
are supposed to be ns.mostang.com/24.1.65.179 and<br>
|
|
CS.ARIZONA.EDU/192.12.69.5) don't know anything about that domain.]<br>
|
|
<p>
|
|
I have updated the HP ScanJet/ScanJet Plus driver to work with the<br>
|
|
2.2 kernels. The latest release can be found at:<br>
|
|
<p>
|
|
<a href="ftp://rvs.ctrl-c.liu.se/pub/wingel/hpscan/hpscan-2.2.7.tar.gz">ftp://rvs.ctrl-c.liu.se/pub/wingel/hpscan/hpscan-2.2.7.tar.gz</a><br>
|
|
<p>
|
|
The version number is the Linux kernel version the driver was made<br>
|
|
for. I'm running 2.2.7 on my system, but the driver ought to work<br>
|
|
with any kernel from the 2.2 series.<br>
|
|
<p>
|
|
Also, since I have an _original_ HP ScanJet I've a patch which makes<br>
|
|
sane-1.0.1 work better with this scanner:<br>
|
|
<p>
|
|
<a href="ftp://rvs.ctrl-c.liu.se/pub/wingel/hpscan/sane-1.0.1-hporig.diff">ftp://rvs.ctrl-c.liu.se/pub/wingel/hpscan/sane-1.0.1-hporig.diff</a><br>
|
|
<p>
|
|
There are actually three unrelated changes in this diff.<br>
|
|
<p>
|
|
The first is a change to hp-scl.c which uses the [ESC]*s3E command to<br>
|
|
retrieve the model of the scanner and stores this in the faked inquiry<br>
|
|
string. Not very important but it's kind of nice to see a proper<br>
|
|
model name instead of just "MODELx".<br>
|
|
<p>
|
|
The second change is in hp-handle.c, it moves the<br>
|
|
sanei_hp_scl_inquire(... SCL_DATA_WIDTH ...) call (that the original<br>
|
|
HP ScanJet doesn't support) from outside the switch statement into the<br>
|
|
HP_SCANMODE_COLOR case where data_width is used.<br>
|
|
<p>
|
|
Finally, because the original HP ScanJet only handles 4 bits of<br>
|
|
grayscale and nothing else in the SANE packages seems to understand<br>
|
|
the format SANE_FRAME_GRAY with a depth of 4, I've made a really ugly<br>
|
|
hack which which detects if the scanner wants to use grayscale and<br>
|
|
expands the 4 bit data into 8 bit data on the fly. This code is<br>
|
|
really ugly and I'm not sure if it deserves to live, but it is kind of<br>
|
|
useful for me since I have such an old scanner.<br>
|
|
<p>
|
|
I'd suggest that the first two changes make it into the sane sources<br>
|
|
since they ought to break nothing and fix a few things. I'd like it<br>
|
|
if the the third change makes into the sources too, but it's up to the<br>
|
|
sense of aesthetics of the maintainer. Which brings me to the<br>
|
|
question, who should I talk to to get this into the sources?<br>
