I'm not sure why that does not work for you,
unless its not font 21001 or something is not
right on the download of the font.

I've done a similar thing in the past.
Based on the font in BAR39W14.CHARSETS.SYS, I have a softfont
file that I use just like PCLELITE.HPENV.SYS.
Its just binary PCL in the file, defining font 39, and sets it
to be the secondary font.

As a secondary font, you can switch to barcode-39 and
back to text using the shift-in ($0E) and shift-out($0F)
characters. Much like you do switching in and out of linedraw
on an hp terminal.

In separate attachment, I will send you
BAR39ENV  and BARTSTLJ.
BARTSTLJ is an ascii file with the shift-in/shift-out
control chars surrounding the data.

:FILE OUT;DEV=200;ENV=BAR39ENV
:FCOPY FROM=BARTSTLJ;TO=*OUT

After I've downloaded the font to my HPLJ4+,
the Test Menu - PCL FONT list
lists my loaded softfonts first, then the internal fonts.
