Typically this is caused by printer output that's padded with
blank lines to fill the page size which causes an automatic page
feed from the printer. The printer interface then sends a form
feed character to eject the last page which is blank.
My solution for this, which goes back over 20 years to Tandy
Xenix systems, it to use a printer interface script/filter that
(a) strips all trailing blank lines from the output, and (b)
sends an appropriate printer sequence to eject the last page.
The printer sequence for many dot-matrix printers is FF (octal
013, hex 0xb). The sequence for HP laser printers is <ESC>E
which is really a reset command, but it will print a page if
there's anything it the printer's buffer.
