The fact that Adobe Reader doesn't print properly under Wine. New York state's income tax forms require Adobe Reader to fill out (enforced with code that specifically checks for Adobe, even though other readers can theoretically work with XFA forms; that said, other readers don't work properly with XFA forms, as I tested on Firefox before the code that blocks out non-Adobe readers even when the XFA is theoretically supported was added), and Adobe Reader doesn't have a Linux version. Unfortunately, the it only prints the first page no matter what, and comes out blurry to boot. I had to dig out my ancient (and dying) Windows 7 laptop to get my tax returns printed. I don't know what I'll do next year, since I'm planning on getting rid of that laptop this year. I guess I'll have to hand write my return, even though my handwriting is garbage and it takes 10 times a long to get my refund that way, as I refuse to pay for tax software or a tax preparer, which are the only ways to e-file taxes in New York if your income is too high for the Free File Alliance.
