Syntax:        TXDLFONT(<expC1>,<expN>,[<expN2>])

     Purpose:       Downloads a soft font file to the printer as a
                    permanent font.

     Arguments:     <expC1> is the soft font file name including
                    extension. Can include drive and directory path.

                    <expN> is the font ID to assign to the soft font
                    for reference later.

                    <expN2> is the printer port to which the printer
                    is connected. Valid values are "LPT1" and "LPT2".
                    If omitted, <expN2> will default to "PRN".

     Returns:        0  Successful
                     1  Invalid number of parameters
                     2  Only 1 parameter passed
                     3  <expN1> font ID not numeric
                     4  <expC2> invalid printer port
                     5  <expC1> Soft font file not found

     Usage:         TXDLFONT() is used to download a soft font file to
                    the printer memory. It can be used by setting it
                    to the primary font using TXSETPFONT().

     Example:       _ret_code = TXDLFONT("C:\FONTS\TR10R#US.SFP", 1)
                    _ret_code = TXDLFONT("C:\FONTS\TR08R#US.SFP", 2)
                    _ret_code = TXSETPFONT(1)
                    (print using font ID #1)

                    _ret_code = TXSETPFONT(2)
                    (Print using font ID #2)
