Exhibit 99

Printronix, Inc., Announces Accelerated Vesting of Certain Stock Options

    IRVINE, Calif.--(BUSINESS WIRE)--Dec. 8, 2005--Printronix, Inc.,
(NASDAQ:PTNX) today announced 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.
