Do I need to print my e-visa in color for immigration in Thailand?

Hi Eric, I too have applied for same LTR-P and my application date is April 24. BOI won’t accept funds in Fidelity money market account so I ended up getting the health insurance. This is perhaps my last remaining issue. I submitted the health insurance yesterday. How long did they take to issue the endorsement after resolving the final issue in your application

Definitely don't need color. The only thing that really matters is the QR code on the visa, and that's in black and white. Actually the only thing having the printed e-visa is for is so that the agent doesn't make a mistake and stamp you in visa exempt. But even then, after you hand them the e-visa and your passport and step away from the counter, ALWAYS, ALWAYS, ALWAYS check the stamp you just received in your passport and make sure it is correct. The BOI office has also emphasized this multiple times. If they give you an incorrect stamp and you don't notice, it could completely invalidate your visa.
