ETHERNET PRINT SERVER
Macintosh computers that do not support EtherTalk will need either an
Ethernet card or an EtherTalk-to-LocalTalk™ router to use the EPS. If you
use a router, it will provide an EtherTalk zone on the LocalTalk network, and
the EPS devices will appear under that zone. If an Ethernet board is installed
in the Macintosh, change from “Built-In” to “EtherTalk” on the Networking
Control Panel, and then the EPS queue(s) should be visible.
Since EPS printers aren’t directly connected to the network, any programs
or utilities that attempt to modify the printer’s AppleTalk settings will fail.
The EPS controls all AppleTalk parameters, such as zone name and job
timeouts, so modifying these settings on the printer itself will have no effect.
You need to reflect changes to the printer’s serial port on the EPS port
setting. Many printers are set to use 7-bit serial characters by default; change
this to 8 if possible.
Printing to a LaserWriter via AppleTalk generally requires bi-directional
PostScript data flow. The EPS parallel port does not have AppleTalk enabled
because the parallel port is an output-only port. Also, if the PostScript
®
printer attached to the EPS cannot provide responses to the printing host,
AppleTalk printing will likely fail. AppleTalk print hosts typically require
responses to PostScript queries sent to the printer.
If you are using a third-party software that provides AppleTalk for UNIX
(or VMS™, etc.), the EPS should be visible like any other AppleTalk device.
Print queues should be able to access the EPS as any other AppleTalk printer.
Because of the variety of software packages and their configurations, setup
details cannot be shown here—see your local documentation for details.
Recall that native Unix and TCP/IP printing methods (lp, lpr, etc.) are
generally easier to setup and administer than non-native AppleTalk printing;
you should use them when possible.
4.5 LAT Host Configuration
Configuring a LAT print queue on your VMS host machine is a two-step
process. You have to create a LAT application port (device) that references
the EPS print resource, and then create a print queue that uses that LAT
application port. ULTRIX™ hosts can also use the LATCP utility, but queue
setup is slightly different.
The LATCP program is used to create the application port and set it to the
appropriate EPS node and service. The following sequence of commands
shows the steps necessary to create an application port. You must be a
privileged user to run LATCP on your host.
