If you aren't located in the US, you may be interested in another adjustment I've made to the tagset, that of the paper size. By default it is set to "0" which is interpreted as Undefined. For us, that results in it trying to print to "letter" sized paper which is only (I believe) used in the states. To set it to A4, you need to find the line:-

CODE
put '0' nl;
and change it to

CODE
put '9' nl;

Other valid papersize values and meanings are listed here:-
