"Printer Location, for example, Printer Room or Dismal Swamp, as displayed in the Print Manager"
And I felt empathy with that documentation writer, as an print subsystem function I was calling was failing, and taking the program I was working on, when it did.
Dismal swamp indeed.
The printer name had trailing spaces, which when passed to the GetGPSDeviceConfig function call, crashed it. For the code-archaeologists out there, I coded around it by doing this:
* The PRINTER-NAME (from sys.printers) is the Device Name of the
* printer, as defined the Install Printer Driver screen of
* Print Manager (InstDD).
MOVE DEVICE-NAME OF PRINTER-TABLE (SUB) TO PBDEVICENAME
PERFORM WITH TEST AFTER
VARYING CBDEVICENAME FROM 12 BY –1
UNTIL GPAM-TEST-CHAR NOT = SPACE
MOVE PBDEVICENAME (CBDEVICENAME:1) TO GPAM-TEST-CHAR
