Some advice in a printing problem ...

I have to develop an application (java) wich access a database and after some calculations updates database an write a receipt (a sort of POS- local administration).
My problem is that if i stick to JSP (which seems like the most elegant and practical solution)- I'll have to print receipts from the workstation browser to a dot matrix printer. As I have no way to print only a few lines of text from the browser (It prints only A4 or some similar formats and my receipts are variable in layouts and sizes) my only choice is to write a client side application (and direct the output to LPT1, without printer driver intervention).
The point is I don't like awt and Swing ...but I'd rather use the browser (not to forget that updating the application would mean to reinstall all the clients)
Can you figure another solution for my issue ?
Best regards

Why would you have to reinstall on updates. Heard of Java Web Start?

Thanks for your message !
I'll take a look at Java Web Start. It seems like a good solution for my problem

No problem.
