What's the origin of the phrase 'Draw a blank'?

Lotteries at that time worked by putting tickets with the participant's names on them into a 'lot pot'. An equal number of notes, some with the prizes written on them and some of which were blank, went into another pot. Pairs of tickets were drawn simultaneously from the two pots. It is easy to see how a failure to succeed came to be associated with drawing a blank.

"A verie rich Lotterie ... without any blancks."
And so it should have been. The tickets cost ten shillings each - at a time when labourers were paid about a shilling a day. The prizes included silver plate and tapestry.
Although the first time that someone 'drew a blank' was in the 16th century, the phrase wasn't recorded in print until the 19th, in Washington Irving's Tales of a Traveller, 1824, in which the plot involves a character being given credit for something he hadn't done:
"It is like being congratulated on the high prize when one has drawn a blank."
Soon after that date the phrase began to be used in hunting circles; for example, from the 1832 Hunting Songs by the impressively named Rowland Eyes Egerton-Warburton:
"The man - whose heart heaves a sigh when his gorse is drawn blank."
Later in the 19th century it became used in a general figurative sense to mean to be unsuccessful in a venture or search of any kind.
