TROUBLESHOOTING THE M204: AppleTalk Problems 153
?
AppleTalk Problems
The Laserwriter icon in the Chooser Menu doesn’t display any printer
destinations
In this situation, these things should be considered:
• Are you using EtherTalk rather than LocalTalk or TokenTalk?
• Is “EtherTalk” chosen in the Control Panel’s Network icon?
• Have you checked the M204 and the Apple system’s Ethernet connections?
• Have you configured the M204 to show up in the correct AppleTalk Zone. Please
see AppleTalk Zones on page 64 for information on doing this.
Windows Problems
Windows NT 3.5x
Queue hangs
Hanging print jobs or queues with Windows NT 3.5x usually means there’s a problem
at the host end. Most likely the printer and print server are sitting on the network wait-
ing for some form of activity but the host is not doing anything. This is very typical for
any LPR printing with Windows NT 3.5 and is possible with NT 3.51 as well.
The first thing to check is that the printer is in fact ready to go, meaning it is willing to
accept more data. The best way to do this is to the use the lpstat command found on
the print server. In fact, this command’s output will tell you where exactly the problem
is. Therefore, you’ll want to telnet into the unit when the hanging occurs and issue
lpstat. Search under the appropriate I/O port you are printing to and see if you see any
messages like:
• “printing data - blocked”
If you see this message with the seconds to the right of the “blocked” message
incrementing with every lpstat command you issue, then the printer is not allow-
ing the print server to pass data to it. This will hang the print queue because the
print server cannot take more data in its output buffer until the “blocked” message
?
