This is not a DOS call, it is a pseudo call.
What we need, is a mnemonic to peek the print driver (Get Printer Info) just like we currently have a poke printer driver (Set Printer Info).
I did a search of the current WDL folders and there is no real reference for the getprinterinfo.
They ware both declared in PrintCtl.INC as:
SET PtrSETPRINTERINFO$ = "@FFE4@" ! Set printer info
SET PtrGETPRINTERINFO$ = "@FFE5@" ! Get printer info
I don't remember if those codes could be used with in a method other than the DOSRW call (like in a Ctl= ) ??
I found out how to use it by going way back in the early versions of the PTRDLG sample program. At one time it offered the available paper sources for each displayed printer. I remember adapting it but found no recent sample code that could do what this one did.
As always, better documentation would be very helpful. The search in the wiki is not that great if you are not sure what you are looking for. Index tables point nowhere...
