I have most of the HP Graphics Language on my website www.tech-diy.com

If you are using a program like Ultiboard, note that the command "AA" 
Arc Absolute which is used to create circles, should be modified.  
Ultiboard specified a 1 degree arc which takes forever to print. You 
can modify the output by downloading the program output as a text 
file into Notepad or MSWord (if using the latter, remember to save 
only as a *.txt file).  Do a REPLACE, searching for ==> ,1; and 
replace with ==> ,15; .  This specifies a 15 degree chord (you can 
use 30, 45, 90 whatever, but 90 will give you a square, not a circle!)
