Item 1.01. Entry Into A Material Definitive Agreement
           ------------------------------------------

On Sunday, December 4, 2005, the Stock Option Committee of the Board of
Directors of Printronix, Inc., ("Printronix", "the company") approved the
immediate vesting of all of the company's "out-of-the-money" stock options
previously granted under its 1994 Stock Incentive Plan. Such stock options had
an exercise price in excess of $15.34, the closing price of the company's common
stock on the NASDAQ National Market on Friday, December 2, 2005. As a result of
this vesting acceleration, which became effective on December 4, 2005, options
to purchase 96,402 shares of Printronix common stock that would otherwise have
vested at various times within the next four years became fully vested. The
accelerated options have exercise prices ranging from $16.62 to $17.73 per
share, a weighted average exercise price of $16.94 per share, and represent 17.5
percent of the company's total outstanding stock options.

Printronix elected to take this action to eliminate approximately $301 thousand
of future compensation expense to be recorded over four years beginning fiscal
year 2007 following the company's adoption of Statement of Financial Accounting
Standards No. 123(R) ("FAS 123R"). The company's Board believes that this action
is in the best interest of its stockholders.
