I will try it some time.

This is good to know.  But with the -mono switch for pdftoppm I don't need 
to change the ending, it is automatically generated as .pbm no.

New problem.  My script is printing the default 75 dpi instead of -res 300 
as instructed.  I ended up making a new script consisting of multiple 
copies of the command that prints each file, changing the file name on 
each line.  I think what did not work was:

for i in *[1,3,5].pbm;  do pbmtolj -res 300 $i > /dev/lp0; done

It ignored the -res 300

I did not yet try David's suggested script, not expecting the resolution 
to work any better with it.

What did work was:
pbmtolj -res 300 filename1.pbm > /dev/lp0

I made a script with 10 copies of this, each with different file number.

I printed 10 odd pages, then printed the even pages on the back, hand 
feeding them all because the paper feeder is feeding all the paper at once 
again.  My partner wants to try replacing the sanded pads with rubber from 
some rollers out of a recycled printer.  It worked for a few pages, same 
as when he cleaned the pads.
