Use the “HP7475A_feed_hpgl_file_01” or “HP7475A_feed_hpgl_file_02” sketches, which are almost the same (only the buffer handling works differently). Both do not work perfect yet for each case, but almost. For very detailed graphics (for example the “noise.hpgl” file), version 02 works better. Instructions how to use the programs are in the comments | Use the “HP7475A_feed_hpgl_file_01” or “HP7475A_feed_hpgl_file_02” sketches, which are almost the same (only the buffer handling works differently).
