Thank you ever so much, Alister, for the super helpful advice. I am
pursuing all the ideas you gave.

Especially thanks for the advice on the foo2zjs printer driver for the HP
P1102 laserjet. It does indeed print with it. I was getting absolutely
nowhere on the Web until I got that advice from you. One problem remains,
however. When printing with Open Office 2.1 (or any other application), it
imposes an undesirably large 10 mm margin at the top of the page. No
adjustments with Open Office will remove that large margin, say to 5 mm, so
I conclude the printer driver is at fault. Can you confirm that that is the
source of the problem? If so, is there any way to edit a printer driver to
remove the imposed margin? Is there maybe something inherent in the HP P1102
printer that causes this problem? Would another printer work better? At the
bottom of the page it prints right off the page with no margin.

I'll try to answer your frequently asked question why I stick with RH9
best I can, but beware it is rare that anyone understands or will accept
my reasons:

o I have an extremely difficult time dealing with rapid-fire obsolescence.
I just cannot cope with abandoning something that I like a lot.

o My RH9 configuration is loaded with the installations and configurations
of highly technical application software, which is so intensive to use
that I don't have time left over to fiddle with an operating system. That
is, I am a LINUX user, not an administrator. It took years to configure
this stuff with scripts etc which do not work with updated operating
systems, and I will not even try to adapt them again.

o I have decided to stick with RH9 indefinitely, and in the future as each
application and routine become obsolete, I will abandon using each of
them, one by one, right up to the point where I expect to abandon
computers altogether and return to typewriters and fountain pens, where I
am comfortable. One by one, Web sites are already refusing me access via
my Konqueror and Firefox 0.8.

o Onward and backwards with RH9!

ppmtosixel(1)						      General Commands Manual						     ppmtosixel(1)

NAME

       ppmtosixel - convert a portable pixmap into DEC sixel format

SYNOPSIS

       ppmtosixel [-raw] [-margin] [ppmfile]

DESCRIPTION

       Reads  a  portable  pixmap  as input.  Produces sixel commands (SIX) as output.	The output is formatted for color printing, e.g. for a DEC
       LJ250 color inkjet printer.

       If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled.  A printer control header and a color assignment table
       begin the SIX file.  Image data is written in a compressed format by default.  A printer control footer ends the image file.

OPTIONS

       -raw   If  specified,  each  pixel  will  be explicitly described in the image file.  If -raw is not specified, output will default to com-
	      pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands.  A raw file is often an order	of  magni-
	      tude larger than a compressed file and prints much slower.

       -margin
	      If  -margin  is not specified, the image will be start at the left margin (of the window, paper, or whatever).  If -margin is speci-
	      fied, a 1.5 inch left margin will offset the image.

PRINTING

       Generally, sixel files must reach the printer unfiltered.  Use the lpr -x option or cat filename > /dev/tty0?.

BUGS

       Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion.  If the original PPM maxval was
       greater	than  100,  rescaling  also reduces the image depth.  While the actual RGB values from the ppm file are more or less retained, the
       color palette of the LJ250 may not match the colors on your screen.  This seems to be a printer limitation.
