I am trying to print to dot matrix printers from my website. I need to
print invoices to multipart forms. Only the fields I specify on screen
should be printed.

I am having trouble with consistent alignments and page setups. I will
be using the application in many locations, with different types of
line printers. Can anyone offer me a solution to print consistently,
the web pages, to different types of dot matrix printers, alignment,
page setup etc.?
