Macintosh Clients and Windows Print Queues - Support

Macintosh Clients and Windows Print Queues

OS X Maverick, Lion Mountain, Leopard, Tiger, and Panther

Pre-Configuration Requirements
 Ensure Macintosh machines have a valid Host A and PTR records in
your campus DNS server and it’s the same DNS server used by the
GoPrint server.
 When using a LPR Printing Port 515 MUST be open on any firewall
between the Macintosh clients and the GoPrint server. Also, check the
local Windows Firewall on the Windows Server to make sure it’s not
blocking port 515.
 Windows LPD Service Feature must be installed and running on the
serve
 SMB or Windows printing option is used, Windows File and Print
Sharing must be enabled on any firewall. Port 139 or 445.
 Macintosh client machine names must be shorter than 15 characters in
order to successfully fit into the allowable button name space displayed
at a print release station.
 Local Administrator account must have Full control access to each print
queue .

If using a Print Release Station determine
the print job identification method!

How Print Jobs display at a Print Release Station:

When using the GoPrint solution with Macintosh clients it is important to
understand how the Macintosh networking set-up effects how print jobs can be
identified at a GoPrint Print Release Station.

Print jobs are identified with as a clickable button displaying either:

username

or

machinename

Note: unless the Web Client is used, in which jobs will appear as the name of the
logged in user of the Web Client). Which identification method you use depends
on your Macintosh login configuration.

The majority of Macintosh lab environments are configured to with single logon
account or a local generic user account. This account is typically set to auto-login
and is usually the same name and password for each machine. Some GoPrint
clients do opt to create an individual username and password for each machine.
Either login type works, with the second option providing a bit more flexibly.

Drawback: When a single generic logon is used, all print jobs appear at a
GoPrint Print Release Station as the same user account, the local generic user
account. With this scenario, machine name identification must be used to
successfully identify a user’s print job. Using this scenario, users must recall the
name of the machine they are printing from.

To help users identify their print jobs, it is a common practice to place a label on
the monitor displaying the machine name and educating users on the proper
printing process.

Important!!!
If proper DNS hostname resolution is not resolvable, then the incorrect hostname
m a y appear, and if NO DNS Host A or DNS Reverse look Record exists, the IP
address of the machine is displayed. See troubleshoot section for more detail.

LPR Printing Option

For ease of compatibility between the two operating systems, the preferred
method GoPrint recommends is to use the standard LPD/LPR printer port.
To connect to a Windows print queue using LPR you must first install the LPD
print monitor on the Windows Print Server.
Advantage: LPR printing bypasses the Windows SMB sharing credentials. SMB
is more difficult to configure and support because it requires a user account to
authenticate that must have Rights to the Print Share.
IMPORTANT: LPD Service must be installed and running on the Windows
print server prior to creating the Macintosh LPR print queue.

Install the Windows 2008/2012 – LPD Service

The LPD daemon is installed as a Feature under the Print and Document Services
Role.

1. Open Server Manager and select Add Features.
2. Navigate down to Print and Document Service Role and check LPD Service.

If you don’t see PDS, then you must go back and install the Role!

Important: A server reboot is required!
The LPD Service is now displayed as Started under Microsoft Services.

Print Using: Recommend using the generic driver. Print job will be sent to the Print
driver installed on the GoPrint print server and print job will be rendered using the
servers print driver.
Note: If a print driver is selected from the list of available drivers on the Macintosh
client, it must match the same driver version installed on the GoPrint server or print
rendering issues will occur. Secondly, the driver MUST be network compatible, as
many Epson drivers are not!

Troubleshooting LPR

Most common issue, jobs display as Paused!

1. Local Administrator doesn’t have Full Control
2. Printer TCP port used for the Queue name instead of the Physical or Share

name.

A look at Windows Event Viewer displays the following message:
The Line Printer Daemon (LPD) service refused a print job from 192.168.1.128 for printer
\\192.168.1.129\coffee because the specified printer does not exist on this computer. Retry
printing from the client using the correct printer name.

Resolution 1 - When creating a Windows print queue, the local Administrator is
automatically granted Full Control. If not, jobs from Mac LPR queues will not able
to communicate.

© 2015 ITC Systems., All rights reserved. | Mac Printing 11

Resolution 2 - Secondly, The Windows print queue Physical name or Share
name MUST be used. Commonly. Users will use the queue TCP Port address.

Once the issue is resolved, opening the print queue and selecting Resume re-
sends all Paused print jobs.

When creating a print queue if the “Setting up” message bar hangs it indicates
issues communicating to the print server or print queue.
Resolution: Ensure server IP and Queue name are correct. Cancel setup.

Printing – printer is in use message:

Possible causes:
 LPD Service is either not installed or the service is not running.
 Port 515 blocked on network between the Mac client and the Windows
Print queue.

Solution 1 – install the LPD service Windows Feature or check to see it’s
running

Step two
In the url field enter the name of the Windows print server followed by a colon and
port 139 and the a forward slash and the name of the print share.

Note: it appears new with leopard and above you must also include the port number in the smb url,
as compared to previous releases.

Click add
At this point, you should be prompt for a Windows username and password with
permissions to the print share.

Option two: To bypass the
username and password prompt
you can manually enter the
username and password directly
into the smb url.
The disadvantage is the
password can be viewed by
logged in users

Example:

smb://username:password@servername:139/printshare

Troubleshooting

If you can't connect to a Windows GoPrint print server and its print queues from your
Macintosh client, here are some things to try:

 Make sure you have typed the GoPrint server name and print queue shared
name correctly.

 If guest access isn't allowed, make sure you have typed the user name and
password exactly as they are entered on the Windows computer. A shared user
account must exist locally on the Mac’s and GoPrint server.

 The password for the user account you are using may need to be reentered on
the Windows computer, or the computer may need to be restarted.

 Try to ping the GoPrint server by DNS and IP address name
 Try to ping the printer(s) by IP address or connect through a browser
If you can ping the GoPrint server and printers, then the TCP/IP connection between
the computers is working.
