DEVOPENSTRUC Field - pszSpoolerParams

pszSpoolerParams (PSZ)

Spooler parameters (optional) are separated by spaces. They are used for scheduling print jobs and are as follows:

The form names that identify the paper to be used, for example, FORM=A4,A5,ENV. The form names are optional; but if they are provided, the spooler is able to hold off printing the jobs until the required form is installed in the printer. If the form name is not provided, the spooler attempts to print the job. The printer driver recognizes that there is a forms problem and displays a FORMS MISMATCH message box.
Priority of the print job, for example, PRTY=60. The priority is specified as an integer in the range 1 through 99; 99 is the highest. The default priority value is 50. The application can use the spooler priority parameter to prioritize its own jobs; however, it is not good practice for an application always to use priority 99 in an attempt to get its jobs printed first.
