Here are some "as is" extras for use with duplexpr.

Be sure to check names of commands, etc. to make avoid conflicts with anything else you may already have installed on your system.

For these first few to work you need to add something like
export PQ="the full path to your print queue"
to $HOME/.bashrc
This is also useful when you need to put anything into the print queue from the command line.
You can just say things like
cp some_file $PQ
without having to retype the full path.

Aliases for printing:
(add to ~/.bash_aliases or ~/.bashrc)


alias pqb='kmprbatches -1' ## show how printing will be broken into batches
alias pql='cd "${PQ}";[ -n "$(ls)" ] && mprb -i * || echo "Print Queue Empty"'  ## list the print queue
alias pqp='cd "${PQ}";[ -n "$(ls)" ] && mprb * || echo "Print Queue Empty"'  ## print the jobs in the print queue

----

Here's a function which can be added to .bashrc .
When you type pq, it will change into your print queue and list the files there.

pq() {
  cd "${PQ}"
  echo -en "\t\t"
  pwd
  ls
  echo
}

AutoKey macro for printing to the print queue from Firefox or Thunderbird.

Set a filter so this only runs if the window title includes mozilla or Thunderbird:
.*Thunderbird.*|.*Mozilla.*
Assign Super+P as the hotkey.

[code]
##print2file

## Copyleft 2012/08/31 - Joseph J. Pollock JPmicrosystems GPL
## Last Modified 2018/02/28 - Handle new Mozilla print dialog
##                            Handle printing please wait
##
## May need modifications to work with Python 3.x
##
## Assign <Super>+p for Firefox and Thunderbird
## to print to file in a special print queue using 
## numbered file names, 01, 02, ... so the print jobs stay in order
##
## The new file name/number will have the same number of digits as the highest
## existing file name/number with left zero padding
## Two digit file names/numbers is the default.
##
## You can "seed" the process using e.g. touch 0000 in an empty print queue
## Intended for use with duplexpr
## http://sourceforge.net/projects/duplexpr/
##
## User must manually create print queue directory (~/pq)
##
## Not sure about the following still being necessary, but it works
## Set all *.print_to_filename variables in prefs.js (about:config)
## to path to print queue/01.ps (or .pdf)
## e.g. /home/shelelia/pq/01.ps (or .pdf)
##
## Using Ctrl+P as the hotkey doesn't seem to work in Firefox any more
## Hotkey <Super>+p
## Window Filter .*Thunderbird.*|.*Mozilla.*
##
## Changes <Super>+p to
## Print to file and looks at the print queue (~/pq) - hard coded
## Finds the last print file number and increments it by one
## Also handles files ending in ".pdf" or ".ps"
## Doesn't send final <Enter> so additional options like Print Selection
## can be set by the user
