HP 8600 works fantastic for yellow letter lined paper. As for the hand written font, go to this website and create your own handwriting in a font www.myscriptfont.com. Scan a copy of a blank yellow letter into MS word as a watermark so you can line the typed font up on to the lines. Change the print setting so that it does not print the watermark (so it only serves as a guide for your font) you will have to make minor adjustments the font spacing in between printed batches, but once it is on it works great. Also I hope you are using a mail merge from your data list in excel. Once you have these components in place and good reliable paper that doesn't jam, its off to the races. Use the mail merge for the envelopes as well so basically all you have to do it print and stuff envelopes. Acquiring an industrial envelope stuffer would eventually be a dream.
