The <strong>EMIS</strong> gateway is managing the printer, i.e. every device (OBC, measuring system, etc.)<br />

must request printer access before printing. The current user of the printer is listed in the<br />

variable “RESOURCE,PRN,STATUS,MODE“:<br />

METER measuring system (e.g. MultiFlow)<br />

QAS QAS device (e.g. MultiSeal)<br />

The printer access was rejected by <strong>EMIS</strong> since another device (a measuring system in the<br />

example above) is occupying the printer.<br />

� O must perform error treatment (e.g. repeat requesting printer access).<br />

b Sending data to the printer<br />

Di The transmission of data to the printer is done like shown in chapter 6.2.1 / page 57 - 0 (step<br />

9). During transmission of data the max. length for the variables TEXT and HEX may not be<br />

exceeded.<br />

c Releasing the printer<br />
