filemaker will work with most printers that have a standard or postscript printer driver.
As long as filemaker can select the printer, then you should be able to format/orient a filemaker layout to work with your printer. My experience (and others) is that there is a fair amount of trial and error involved with getting the sizing down right. I've found that it's easiest to start with an empty grey outlined box and size that to the border of your print area, then format your content to fit in the box, and finally remove the box when you're done.
As another tip, when you insert merge fields in your text boxes, EG <<Address1>>, as long as you leave the outer < > styled as you want, then you can resize the inside text to a smaller size to save on space without losing formatting. This works great for getting a lot of merge text together in one line. ( to example further, if you break it down to < <field> >, then format the fonts to 12pt 6pt 12pt, then you will have 12pt merge text, even though you saved space shrinking the inside of the merge tag).
Thank you for the advices.
Yeah, I have no chance to install and try the printer without buying it first.
