Ink-stained wretch in search of ink-stained wretch

Seattle-based journalist Sanjay Bhatt has created "The Ink-Stained Wretches Club," a Ning group, according to the Fitz and Jen blog on the Editor & Publisher Web site.

Being an ink-stained wretch, I joined up. But that got me wondering who coined the commonly-used phrase "ink-stained wretch?" A cursory walk through Google turned up no definitive answer. But I did find where one person made a stab at it.

Any of you "ink-stained wretches" know the history of that one?
