there is no additional space anywhere there
however, this is html output.
if your printer does not understand it, i would suggest you to go to wppizza->templates->print order , add a new template, set this new template to plaintext and to be used and then see if your printer can deal with that (edit the template settings as appropriate)
other than that there is nothing else i would be able to suggest here.
if you printer prints new lines where there are no new lines , you will have to ask the manufacturer
