1st printing- (July 1982)- 2.95 cover price.
2nd printing (October 1987)- $3.50 cover price. This is the only one that marks itself boldly as a second printing in traditional comic book indicia style and does so immediately after the Fall '82 cover date.
3rd printing (February 1992)- $3.95 cover price.
5th printing (May 1995)- $4.95 cover price. This is actually the fourth printing, but states otherwise apparently due to a misprint.
The information regarding the exact printing and release date is found towards the end of the indicia in these subsequent printings.
On-sale date, month only, from Amazing Heroes #13, with note "[July-delayed from May]".
