Hello.
It´s kind of easy. Just download JasperSoftStudio community edition, add fileds (match there the field value - Class (Math decimal for numbers etc...) then just add the fields on the report. It took me some time to figure things out, but it ´s great, i assume you want print some official papers.
As for the images, it´s better to upload it on web and assign there link to webpage. Offline images are problem if not located on same place (i use multiple computers with memento and print options, this was a problem ...
There are lot of stuff about this you just have to ask what do you need.... I use 80mm thermal printer , A4 printers and 80mm sticker printer connected to memento / jasper reports.
If you have some concrete question just ask my english aint that good but i will try to help. Lot of guys here helped me to develop own system :)
