Hello kenfrantz. I understand you would like to print in different sizes. This HP document contains information on how print sizes and settings are controlled from our own software: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01455146
When printing in a different size, assuming the settings in our software are correct, ensure the settings in the program you are utilizing are also correct. Please inform me when you complete troubleshooting, and I will continue to assist you if necessary.
