CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of U.S. Provisional Patent Application No. 60/714,633, filed Sep. 6, 2005, the contents of which are hereby incorporated by reference as if stated in full herein. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates generally to printers and printer connected hardware used in cash-less slot machines and gaming, and more specifically to hardware and software operating within this equipment performing promotional ticket printing, promotional data basing and printer and printer connected hardware based promotional ticket triggering. 
     The gaming machine manufacturing industry provides a variety of gaming machines for the amusement of gambling players. An exemplary gaming machine is a slot machine. A slot machine is an electro-mechanical game wherein chance or the skill of a player determines the outcome of the game. Slot machines are usually found in casinos or other more informal gaming establishments. 
     The gaming machine manufacturers have provided cash-less enabled games to the market for the last five years, and there now exists a broad population of such games in the casino industry. Cash-less enabled games are so named due to the fact that they can conduct their player&#39;s financial exchange with a mixture of traditional paper and coin currency and vouchers redeemable for cash or game credits. 
     Two pieces of necessary equipment for a cash-less enabled game is a printer to produce the vouchers, and a bill acceptor that supports automatic reading of the vouchers. In a cash-less enabled gaming system, when a player cashes out, the game is signaled and depending on the size of the pay out, it can either present coins in the tradition method of a slot machine, or it can cause the printers which are installed in such machines to produce a voucher including the value of the pay out. The voucher may then either be redeemed for cash at the cashier&#39;s cage for currency, or it may be inserted into one of the casino&#39;s games&#39; bill acceptor, at which point the network and server to which the game is connected will recognize the voucher as valid, redeem it and place the appropriate amount of playing credits on the game. 
     Over the years, cash-less enabled games have found an increasing acceptance and use in the gaming industry with both the players, who enjoy the speed of play and ease of transporting their winnings around the casino, and the casinos who have realized significant labor savings in the form of reduced coin hopper reloads in the games, and an increase in revenue due to speed of play. The broad installation base of cash-less enabled games guarantees a wide installed base of networked games and their installed printers which may be used to print coupons and promotions for the captive player audiences. 
     In typical casino operations, the games are networked to a main server which monitors various metrics of activity on the games for regulatory, accounting and promotional activities related to frequent player club cards which participating patrons insert into the games when they play. The server related to promotions for player club cards is referred to as the Player Tracking Sever. Gaming machines share real-time play metrics with the Player Tracking Server in order to support frequent player incentives.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  is an illustration of a block diagram of a PCS  100  connected to one or more GVPs,  102   a  and  102   b  installed in respective gaming machines,  104   a  and  104   b . The PCS, as shown in the diagram, is a server whose responsibility is to direct the promotional activity of the gaming machine installed GVPs. The features of the PCS may be implemented by a process or processes  101  encoded in processor executable code and stored in a computer-readable storage medium. 
     In the system, each GVP has two or more ports. Referring to GVP  102   a , a primary port  106  connects the GVP or unit to a controller  108  of the gaming machine in which the GVP is installed for receiving cash-out voucher signals for printing cash-out vouchers, and a second auxiliary port  110  for connection to the PCS for promotional couponing. The features of the GVP may be implemented by a process or processes  103  encoded in processor executable code stored in a computer-readable storage medium. 
     Each GVP has a unique address by which it can specifically be selected. As an example, in an Ethernet network the GVP&#39;s address may be an IP network address on the network. In one embodiment of a GVP in accordance with the present invention, the GVP&#39;s unique network address is configured by operator configurable address switches coupled to a processor of the GVP. 
     In another embodiment of a GVP in accordance with the present invention, the GVP&#39;s unique network address is assigned by the PCS and the GVP stores the GVP&#39;s address in memory for permanent use until a new address is assigned to the GVP by the PCS. 
     In another embodiment of a GVP in accordance with the present invention, the GVP stores an identification of the gaming machine into which the GVP is installed into a memory coupled to a processor of the GVP. 
     In another embodiment of a GVP in accordance with the present invention, the GVP&#39;s unique network address is a fixed value as a function of the GVP&#39;s hardware. 
     In another embodiment of a GVP in accordance with the present invention, the GVP, after boot-up, receives cash-out voucher signals from the gaming machine over the GVP&#39;s primary port, and the GVP verifies that a first gaming machine identifier in the cash-out signals is the same as a second gaming machine identifier previously recorded in the GVP&#39;s memory as to which gaming machine the GVP is installed. 
     In one exemplary embodiment of a GVP, the GVP, as it has two masters, one is the gaming machine controller and the other is the PCS, arbitrates traffic on the two channels. The complexity of this is increased since the two masters are operating asynchronously from each other. An example of one arbitration scheme would be the GVP always giving priority to a cash-out voucher print job which comes from the gaming machine (on the primary port), and then queuing a coupon print job from the PCS (on the second auxiliary port) behind the voucher. Another example of an arbitration scheme would be the GVP receiving a coupon print job on its second auxiliary port, and then holding the coupon for a period of time awaiting arrival of a cash-out voucher on the primary port. If the cash-out voucher didn&#39;t arrive within a reasonable amount of time, the coupon could either be printed or canceled by the GVP. 
     In another exemplary embodiment of a GVP in accordance with the present invention, in addition to coupon print data, the GVP receives certain static promotional campaign data on its second auxiliary port. The static data includes graphic icons that are used to print the various coupons, portions of the coupons which would never change with an award, and optionally, a set of trigger conditions which would cause the GVP to trigger a coupon. 
     In another exemplary embodiment of a gaming promotional system in accordance with the present invention, the PCS sends static data to the GVP, the static data including one or more fixed portions of printed indicia for promotional award coupons to be utilized by the GVP in printing promotional award coupons and the GVP stores the static data in a memory. 
     In another exemplary embodiment of a gaming promotional system in accordance with the present invention, the static data further includes coupon trigger or play metrics. 
     In another exemplary embodiment of a gaming promotional system in accordance with the present invention, the static data further includes coupon issuance control parameters. 
     In another exemplary embodiment of a gaming promotional system in accordance with the present invention, the static data further includes a unique promotional campaign identifier. 
     In another exemplary embodiment of a gaming promotional system in accordance with the present invention, the PCS sends variable data includes portions of printed indicia for promotional award coupons to the GVP. The variable data includes a unique promotional campaign identifier. The GVP confirms that the promotional campaign identifier matches the previously stored static data, combines the fixed and variable portions of indicia data, and prints a promotional award coupon based on the combined fixed and variable portions of indicia data. 
     In another exemplary embodiment of a gaming promotional system in accordance with the present invention, the PCS requests the GVP to send status as to the identifier of the promotional campaign static data file which resides in the GVP&#39;s memory. Then the PCS determines if the campaign identifier in the GVP matches an identifier of the promotional campaign that the PCS is currently operating, and if not, the PCS sends new promotional campaign static data to the GVP which matches the promotional campaign which the PCS is currently operating. 
     In another exemplary embodiment of a GVP in accordance with the present invention, the PCS broadcasts time and date data on a periodic basis to the GVP, and the GVP uses the time and date data to synchronize the GVP&#39;s own internal clock. 
     In another exemplary embodiment of a GVP in accordance with the present invention, the GVP, upon receiving cash-out voucher signals from the gaming machine over the GVP&#39;s primary port, extracts time and date data from cash-out voucher signals and uses the time and date data to synchronize the GVP&#39;s internal clock. 
       FIG. 2  is an illustration of a block diagram showing the PCS  100 , Player Tracking System (PTS)  200 , gaming machine  104   a  and GVP  102   a  connected in relation to each other. In  FIG. 2 , the PTS receives information about player activity on the gaming machine  104   a  via an interface board  201  to which the PTS is connected. As used herein, data packets  202  include player gaming machine activity as Player Session Packets (“PSPs”), and as examples of the data is an indication that a player had bet so much on a particular game, had won or lost the bet, the amount of a win, the amount of money deposited in the machine, if a player was cashing out, and so on. 
     The PTS then passes the PSP information  204  to the PCS as shown in the diagram. Next, the PCS determines by processing the packet which gaming machine the PSP originated from, looks up from an internal database  206  having a link table in which a GVP network address is related to that gaming machine, and forwards the PSP  208  to that network address, essentially sending it to the GVP. 
     The GVP then processes information from the PSP to determine if a coupon trigger condition is met. If a condition is met, the GVP informs the PCS of an award, requests a validation identifier for the coupon, and obtains permission from the PCS to print the coupon. If approved, additional handshaking is used to ensure that the coupon was successfully produced by the GVP, and the PCS then logs the validation number and the award type into its internal memory for later reconciliation. 
     In another exemplary embodiment of a gaming promotional system, the PCS performs the analysis of the PSPs against a set of trigger conditions, and when a condition is met, the PCS signals the GVP with a coupon and a validation sequence for the coupon. Upon receipt of data from the PCS, the GVP produces the requested coupon. In this embodiment, handshaking applicable to the success or failure of the coupon print job would is also conducted. 
     In addition, as the PTS is coupled to the PCS, the PCS may transmit data related to outstanding and redeemed promotional award coupons from the PCS&#39;s memory (not shown) to the PTS.

       FIG. 4  is not intended to be all inclusive, and its is likely that there would be other casino systems to which the PCS will be connected when deployed. 
       FIG. 5  is an illustration of an exemplary promotional database which includes defined coupons and triggers in accordance with an exemplary embodiment of the present invention.  FIG. 5  illustrates trigger matrix logic and process within the GVP  102   a  (of  FIG. 1 ), the PCS  100  (of  FIG. 1 ) or portions shared between the two, depending on where data processing of the PSP  202  (of  FIG. 2 ) resides. At the top of the diagram are exemplary different logical triggers or play metrics utilized in the printer for initiating printing of the coupons. The five examples given are: date  502 , time  504 , frequency of issuance  506 , duration of play  508 , and other parameters  510  such as player I.D., amount of money in play, duration of the current session of play and the like. In the lower part of the diagram, the coupon database stack  512  is pictured. The stack of coupons are a plurality of pre-defined coupons which can printed anytime the set of trigger conditions to which they are associated are satisfied. These trigger conditions can operate independently or in logical combination. The coupon selector logic module  500  shown is tasked with analyzing trigger information as it becomes available and determine which coupon  514  should be printed in response to the information. 
     Additional processing, not shown, occurs in the PCS where the amount of coupons permitted in the campaign, an additional randomness of issue can be applied, and other possible global promotional campaign parameters may be checked before print authorization. 
     In addition, the play metrics may include: anytime a cash-out voucher is printed, printing of a cash-out voucher for greater than, equal to, or less than a specified amount of money, an amount of money wagered over a particular time period, an amount of money won over a particular time period, an amount of money lost over a particular time period, a duration of play on the gaming machine, anytime a player adds money or credits to the gaming machine in an amount greater than, equal to or less than a specified amount, a time when the gaming machine is played or cashed-out, a day when the gaming machine is played or cashed-out, a date when the gaming machine is played or cashed-out, an average percentage of the maximum wagering on the gaming machine which the player&#39;s activity represents, a random percentage chance that a coupon will be issued when a player cashes out, participation of a player in a frequent player club, a player&#39;s birthday date, for participating frequent player club members, classification of the player as applied to modify any play metrics. 
     In one embodiment of a gaming promotional system in accordance with the present invention, the GVP downloads from the PCS the play metrics and analyzes gaming machine activity passed to it by the PCS using the play metrics. The GVP then produces a coupon when the play metrics are satisfied. 
     In another embodiment of a gaming promotional system in accordance with the present invention, the PCS further includes a database storing a set of control parameters used to select a type and quantity of coupons to issue related to play metrics used to trigger issuance of coupons, the control parameters operating separately or in combination with each coupon. 
     In another embodiment of a gaming promotional system in accordance with the present invention, the GVP further includes a database storing a set of control parameters which are used to select a type and quantity of coupons to issue related to play metrics used to trigger issuance of coupons, the control parameters operating separately or in combination with each coupon. 
     In another embodiment of a gaming promotional system in accordance with the present invention, the control parameters include a total quantity of a coupon is issued before the coupon is retired, a frequency of issuance of a coupon, one issued every time a specified number of trigger events occurs, a frequency of issuance of a coupon based on a random chance of one in every so many trigger events, an alternative coupon should a particular coupon fail to print for lack of satisfying all of the coupon&#39;s play metrics or the coupon&#39;s specified set of control parameters. 
     Although the present invention has been described in certain specific embodiments, many additional modifications and variations would be apparent to those skilled in the art. It is therefore to be understood that this invention may be practiced otherwise than as specifically described. Thus, the present embodiments of the invention should be considered in all respects as illustrative and not restrictive, the scope of the invention to be determined by any claims supportable by this application and the claims&#39; equivalents rather than the foregoing description.
