Re: multi-part forms with barcodes and places for signatures... There is no
way you can feed any kind of multi-part form through a standard laser
printer.  It's because all common laser printers are designed to use
cut-sheet paper.  There are a few laser printers which do use the tractor
feed approach and with those you might be successfull with multi-part paper
stock.

Depending upon how things are setup, you might want to look at printing bar
codes from the dot matix printers.  With some custom programming, most bar
code formats should be printable on the various HP brand printers.  The bar
code printing done by most HP printers is simply escape sequence controlled.
You can also use a bitmap approach to do non-standard (to HP) bar codes.
