Receipt Printing Fonts

Avast ye swabbies! Freshly pirated from Wizzyrea, there's all ye needs know about hackin' yer receipt printer! Yarrr, font be a cruel mistress.

There is a lot you could do to the fonts/receipts, a decent primer on font styling in CSS is available here: http://www.w3schools.com/css/css_font.asp. If you are using Koha 3.4+, there is the IntranetUserCSS preference that you can use

#receipt {
   font: 15px, arial, sans-serif; /*editing to your whim, of course*/
}

to style your receipt fonts.
