spec-version

Arguments: printer

Returns an integer indicating the version of the Windows printer information facility that is supported by the printer driver of printer. Specifically, if the value is #x400 or greater, then that printer driver knows how to give information on several new printer attributes that were added to the Windows printer information facility in Win95 and NT 4.0. If the number is lower than #x400, than some of the properties of printer may be nil because the printer driver did not know how to supply the newer values to the operating system.

spec-version is a property of the printer class.

This function is not setf'able. You must specify a value for this property when a printer stream is created with open-stream. (It can also be changed in the printer job control dialog when printing is initiated by a user, but the initial value in the job control dialog cannot be changed.)
