CHAPTER 6 TROUBLESHOOTING
8.12 AppleTalk Troubleshooting
If you cannot print from an AppleTalk for Macintosh computer and you have checked the
hardware and network as described in the previous steps, then check the following:
(1) Make sure that you are running Phase 2 AppleTalk and that you have selected the correct
network interface from the Network Control Panel on the Macintosh.
(2) Make sure that the AppleTalk protocol of the print server is enabled.
(3) If you have a large network, make sure that you have the Laser Writer V8.xx or equivalent
driver, since earlier versions may cause PostScript errors. Also, verify that you get the
correct printer information when you select Printer Info from the Setup button in the
Chooser.
(4) Make sure that you have selected the correct Printer Description File (PPD) from the
Chooser (otherwise PostScript errors may result)
(5) Verify that you have selected the correct AppleTalk zone. Because the print server gets its
zone information from router broadcasts, it may not be in the zone you expect, and will
therefore not show up in the Chooser. If this is the case, you may need to force the zone
name using BRAdmin, a web browser or the SET APPLETALK ZONE command from
TELNET.
8.13 Apple TCP/IP Printing (System 8.6 or later)
(1) From system 8.6 or later, Apple introduced the Desktop Printer Utility. This utility allows
TCP/IP printing from a Macintosh, which has the USB interface.
(2) From the "Internet Printer" dialogue, please ensure that you enter the correct service
name in the "Queue" option. For example, for NC-4100h series network cards enter
BRN_xxxxxx_P1_AT (where xxxxxx is the last six digits of the MAC address of the NC-
3000 series card). For NC-2000 series network cards enter BRO_xxxxxx_P1_AT (where
xxxxxx is the last six digits of the MAC address of the NC-4100h network card).
(3) This method of printing requires that the printer supports PostScript. If your printer does
not support PostScript printing. Please consult your printer manual to see if your printer
supports PostScript.
8.14 DLC/LLC Troubleshooting
If you are having trouble printing with DLC/LLC, check the following:
(1) Make sure that the DLC/LLC protocol is enabled using either BRAdmin, a web browser or
TELNET.
(2) Make sure that the MAC address of the Windows setting is the same as shown in the
print configuration page printout.
8.15 LAT Troubleshooting
If you cannot print from a VMS system and you have checked the hardware and network as
described in the previous steps, then check the following (note that it is always a good idea to try
creating a new queue with a different LAT port to reduce the possibility of setup errors):
