Then that would make it a label printer
It is just an envelope printer, which is easier as all I need to know is the hight and width of an envelope and then the program can do the match from there automatically.
With labels they can all be different. So simply knowing the hight and width of the paper isn't good enough, the program also has to know the space between each label, how many labels per row and then how many rows. Then it will have all the math needed to do the print. So since I didn't have a way to get the huge list of label sheets out there and what all their specs are for each one I didn't add support for it, thus why it is only called a envelope printer
The reason is that my xmas card collection for sending (in the UK) all have different sized envelopes!
In that case it might be better to do all the envelopes that are the same size and then the next batch of envelopes that are a different size. That way all you have to do is simply change the envelope size in the program once instead of for each envelope
