Description of problem:
/usr/bin/smbprint derives the location of the spool directory from the last 
parameter passed to it (which is the acct file). It does this by means of \$$#, 
which works as long as $# expands to a single digit.
On my system however, smbprint is called by LPRng with 22 parameters. This 
causes the above to expand to $22, which expands to <whatever is in $2>2 (i.e. 
a digit 2 appended to the value of $2).
In order to avoid this braces are needed, as follows: \${$#}
