Does anyone know how to print this comparison operator (which looks like a combination of triangle and equal) between two operands?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Please have a look at this question: tex.stackexchange.com/questions/14/how-to-look-up-a-math-symbol I tried Detexify and it works. – Marco Daniel Dec 17 '11 at 13:24
@MarcoDaniel: I tried, too, but Detexify didn't list this particular symbol. (Perhaps I'm simply bad at drawing, though.) – lockstep Dec 17 '11 at 13:32
This symbol is provided by stmaryrd as \trianglelefteqslant and by mathabx as \trianglelefteq. – diabonas Dec 17 '11 at 13:36
@MarcoDaniel: I could make DeTeXify give me the right symbol either. – Martin Scharrer Dec 17 '11 at 14:36
\trianglelefteqslant actually isn't in Detexify. If you go to the symbol table and enter triangleleft, you won't find it among the results. The maintainer, however, isn't accepting symbol requests until the new version of Detexify is deployed. Nonetheless, \trianglelefteqslant can be found on page 40 of The Comprehensive LaTeX Symbol List, hence my vote to close. – doncherry Dec 17 '11 at 15:08

This is \trianglelefteqslant from the stmaryrd package.
