How can I print all (400) of my asset life histories without babysitting my printer for an entire day?

Here's the best workaround I could think of:

Under the File tab (after Review along the top of your screen), you can select Print/Save for your records

Then choose to Save as a pdf.  

Once that's on your desktop, you can choose to print only specific forms, so you could just pick 10 or 20 at a time, as you have the time to do them.

I was going to say that too.  I vote for saving a pdf.

Printing the entire return (or saving the entire return to a PDF) does NOT include any of the asset history records.  My return with all detailed worksheets is over 2200 pages.  That does NOT include any asset history records.  Try it.  Really, it takes a full day to print these, and I must be at the desk for every moment.
