Just to clarify some points, there is no need for this to be of print quality - it is an online representation of the vinyl they will recieve in the post.
Also, the main problem I've got with GD, is generating text that is stretched? Do I need to generate a text image then stretch this using normal resize functions??

I can't see how imagemagick helps here, it's a bitmap manipulator just like
GD. so it's either use something that generates vector based output (and let
the printersubsytem handle the conversion) or generate massive bitmaps and
print them at a very high DPI.

I'll take your word on that, I've never played with imagemagick, having found
GD to produce quality good enough for my needs.
