Abstract

OS/2* printer device drivers are individual executable files included with the base operating system. AIX* printer device drivers are the AIX files that communicate with the actual printer devices. When an OS/2 client queries an AIX server about a printer device driver name, the problem arises as to how the AIX server can retrieve its system and return a valid OS/2 printer device driver name.

How AIX Server Replies Query of OS/2 Printer Device Driver Name

       OS/2* printer device drivers are individual executable
files included with the base operating system.  AIX* printer device
drivers are the AIX files that communicate with the actual printer
devices.  When an OS/2 client queries an AIX server about a printer
device driver name, the problem arises as to how the AIX server can
retrieve its system and return a valid OS/2 printer device driver
name.

      There is a need for the server to return a valid OS/2 printer
device driver name in order to support the query device API call from
an OS/2 client; i.e., the PM printing requirement from OS/2 is for a
server to provide an OS/2 printer device driver name in response to
the query device API call.  OS/2 print subsystem will then ask the
user to install this printer device on the client machine.

      A printer device driver can be installed or deleted for
printers and plotters via the OS/2 Print Manager.  The printer device
drivers are in charge of knowing any detail of the printer they
support, such as forms, orientation, resolution, default spool file
type, etc.

      Under AIX there are two basic methods that can be employed to
drive or use printers.  They are:
1.   printing by directly addressing the printer device driver
     In this environment an application or a user prints directly via
the printer device driver.  An application sends output to the
printer without the involvement of the print subsystem.
2.   printing b...
