Feeb has posted his nutty scanner/printer methods before.

#####################################################################

SANE fully supports the HP6200C, and I mean FULLY.

The following script will scan a document in high res
grayscale, threshold to bi-tonal using the best parameters,
compress with the highly efficient JBIG2 algorithm, and
then produce a PDF.

Of course, you can archive the original high res grayscale
if desired, and do virtually any-fucking-thing else, by
a suitable adjustment of the script.

Step 1 -- discover all relevant scanner parameters with:

scanimage --help --device hp:libusb:major:minor

Step 2 -- program these into the bash script

Step 3 -- execute the bash script as follows:

doc2pdf.sh outputfile.pdf gamma major minor

===================================================
doc2pdf.sh for the HP6200C
===================================================

#! /bin/bash
# HP6200C
# scans to 12-bit 300dpi gray scale pgm
# doc2pdf.sh file.pdf gamma major minor

gamma=$2
outfile=$1
major=$3
minor=$4

scanimage -p -d hp:libusb:$major:$minor --format pnm --mode Gray --depth 
12 \
--resolution 300 --speed="Normal"  --output-8bit="no"\
--source Normal \
--custom-gamma="yes" \
--gamma-table `gamma4scanimage $gamma 0 255 255 255` \
| pamthreshold | pnmtopnm > ${outfile%.pdf}.pbm

jbig2 -s -p ${outfile%.pdf}.pbm > ${outfile%.pdf}.jb2
python pdf.py output > $outfile

========================================================================

Notice Feeb makes everything much, much harder than it needs to be.

I'd say at least a full day to learn how to shell script and set options 
and pipe data from/to scanimage, jbig2, pamthreshold and pnmtopnm.  Of 
course the liar will tell you he did it all in 15 minutes [1]

It's very likely the GUI-driven scanner software will produce a 
visually-identical .pdf document with a few mouse clicks.



[1]  Feeb told me he wrote this C program in "less than 2 minutes":

------------------------------------------------------------------------------------------------
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
int i, sins, rnd_index_1, rnd_index_2;
time_t t;

// define strings
char *sin[7] = {"lust","gluttony","greed","sloth","wrath","envy","pride"};
char *sinner[23] = 
{"DFS","Octavian","7","Melzzzzz","Fabian","Gohde","Kohlmann","Takuya","Ahlstrom","shitv","Greycloud","Marek","Desk 
Rabbit","-hh","JED","Relf","wRonG","Sandman","sbd","Carroll","Tattoo","Bloaty","Dumb 
Willie"};
int sinner_ptr[23];
char *organ[4] = {"heart","stomach","dick","peabrain"};
char *desc[4] = {"beautiful","nasty","wonderful","repulsive"};

// initialize RNG and index array
srand((unsigned) time(&t));
for(i=0; i<=22; i++) { sinner_ptr[i]=i; }

// main loop
for(sins=1; sins<=50; sins++)
{
// get first rnd index
rnd_index_1 = sinner_ptr[rand() % 23];

// swap index pointers
i=sinner_ptr[rnd_index_1]; sinner_ptr[rnd_index_1]=sinner_ptr[22]; 
sinner_ptr[22]=i;

// get second rnd index on reduced set
rnd_index_2 = sinner_ptr[rand() % 22];
// print all rnd strings
fprintf(stdout, "%d The %s %s holds in his %s for %s is a %s thing.\n", 
sins, sin[rand() % 7], sinner[rnd_index_1], organ[rand() % 4], 
sinner[rnd_index_2], desc[rand() % 4]);
}

return(0);
}
------------------------------------------------------------------------------------------------

What a liar.  And it didn't work right, of course.


Before I forget: thanks for being the only poster besides me that bashes 
that fraud.
