Mysterious computer messages

Today my computer was taking forever to log on. Frustrated by my two minute wait, I restarted it with a cold boot. When it chose to actually allow me access to my desktop there was a DOS window open on-screen. This message was one of the lines of text.

Please check to see if the printer exists.

Now, I assume that our printers aren't suffering from existential angst but I could be wrong. I would like to have a discussion with the person who thought up this text but I think it would be safe to assume that they wouldn't find my interpretation amusing.
