My guess is if your printer prints directly from the file (i.e. it's not
PostScript printer or something), then the printer is printing from a
character look-up table in its ROM. Is the "freak character" French (?)
character "C" with funny tail? If that is so, then it must be updated to
have Euro symbol in its ROM. If your HP printer is several years old and
doesn't contain Euro symbol, then you'll have to somehow generate a
graphic character and send it to the printer as graphic or update the
character set in ROM.

The printer may support many character sets, but the text file may not
conatin the code to switch to the character set with the characters you
want. See the printers reference manual, and update the program that makes
the text file to add the code sequence required to set the character set.

Or the printer is so old (3 or 4 years or older) that the euro symbol is not
available.
Then you have to upload the font yourself.

How do I upload the font myself. Did get to see some useful information at
the HP site about the EURO symbol.But not sure if it will work in DOS.

TIA & Cheers

You can easily send the symbol as a PCL  raster graphic [1b 2a 62 #...# 57
data]. #...# = number of bytes
you want to upload as data.

or you can change the character code of a special character: [1b 2a 63 #...#
45]. #...# = character code.
then you upload the data for this character code: [1b 28 73 #...# 57 data]
#...# = number of bytes and
then the data.

hope this helps

If you print plain text to the printer, you have to make sure the printer
itself has the Euro character as part of its character set. Most of them
don't; read the instruction manual to see if yours does.

In Windows there are True Type fonts with the Euro character. When a Word
document containing these characters (and fonts) is printed it gets
processed by the GDI which converts it to a format the printer can
understand. This is at a different level to printing text and contains
instructions such as "print circle", "print dot", "set colour to blue" and
the like.

I am not very sure of how raster graphics works.    I believe the character is drawn up on a eight
by eight or more raster or perhaps less, e.g.:

128          x                 x             sum(1 to 128) = 256dec = FFh
64            x                 x              16 + 8 = 24dec = 18h
32            x                 x
16            x x x x x x x x
   8            x x x x x x x x             this would then produce a eight digit number: 256,
   4            x                 x           24,24,24,24,24,24,256 by  adding the relative numbers
   2            x                 x             together for each column.    Would I then be
   1            x                 x             required to send (all in hex):

"1b 2a 62 8 57 FF 18 18 18 18 18 18 FF" to the printer to print this H character ?
    Have I got it right ?
