Note: The contents of this article are specific to Presto Server version 2.7 and later.  If you are running an earlier version of Presto 2, we encourage you to upgrade as soon as possible.  Your purchase of the Presto 2 license entitles you to free upgrades to all Presto 2.x versions.

Overview

Accessing the Presto UI

Access to the Presto service is available in the following ways:

  • The Presto Application on the host computer
  • A browser on a Presto Host using the loopback address in the following format: https://127-0-0-1.collobos.net:9631
  • A browser pointed to the IP address of a system running either the Primary Presto instance or an Extender in the following format: https://192-168-5-1.collobos.net:9631
  • The Presto App installed on a Mobile and logged in as an Administrator.

Note: If the Admin UI fails to load, see Troubleshooting the Admin UI in Presto Troubleshooting.

Communication Indicator

The triangle icon in the lower right corner indicates whether or not the Presto Application is communicating with the Presto Service on the hosting system.  If it is showing as red with a line through it, this indicates that it is not communication.

If the Presto Application is not communicating with the Service, the information in Presto will not be up-to-date and any edits will fail.

For information about troubleshooting an instance of Presto that is not communicating, see Troubleshooting Hosts in  Presto Troubleshooting.

Users

The Users tab is where you can view all users, both active and inactive.

Adding Users

There are two events that cause a user to be added to the Users list, if not already on it:

  • A User logs into the Presto application
  • A User prints, whether or not they have authenticated.

All authenticated Users will appear as their full name, as it appears in the authentication directory.  Unauthenticated users will appear as 'Guest'.  All Users have the IP address of the most recent system on which they either logged in or printed.  When a user is authenticated, if the IP address matches the IP address of an existing Guest User, the Guest User is removed from the list.

We recommend setting printers to 'Require Authentication' to allow administrators the greatest degree of visibility and control. For more information, see  Printers.

Active vs. Inactive Users

A User will appear as active if they have either logged in the Presto application or have printed, whether authenticated or not, in the past 30 days.

A user becomes inactive when they haven't logged in the Presto application or printed in the past 30 days.

Administrator Users

An Administrator have the ability to administer Presto wherever/whenever they are logged in.  They are also able to set any other user to be an Administrator.

Search for a User

The search bar will allow you to search for Users.  It accepts a single, non-case sensitive term and will match the pattern across User names and tags.

Deleting a Host

Delete an Extender by selecting the Host, clicking the vertical ellipsis and selecting Delete from the menu.  This will terminate the connection.  You can then proceed to uninstall Presto from the hosting system.

Rules

This tab will allow you to create, view and manage Rules.  Rules deliver Administrators a powerful toolkit to serve their users the right printers under a specific set of criteria.  This logic will scale to the largest environments.

Rules Overview
  • Rules use boolean logic to manage printer advertisement in coordination with Tags, which are arbitrary strings added as identifiers to Printers and/or Users.  See also Printers and Users.
  • A generic default printer sharing rule is enabled upon installation of the Primary instance of Presto. Deactivate this rule prior to implementing custom Rules.

Note: Rules can be eliminated altogether through the use of Presto Secure Release, which is included with Presto.  For more details, see  Presto Secure Release.

Search for a Rule

The search bar will allow you to search for Rules.  It accepts a single, non-case sensitive term and will match the pattern across Rule names.

Managing Rules

To view the settings of a single Rule, select the name of the Rule.  To view the settings of multiple Rules, use the radio buttons to multi-select. To change settings for selected Rule(s), click the vertical ellipsis from the upper-right corner and click Edit.  To save any changes, click Save from the same menu.  To cancel changes, select Cancel from the same menu. 

Description of Rules Settings
Item Description
Name Editable.
Enabled Indicates whether this rule is in use by Presto in enabling access to Printer(s) to User(s). Editable.
Created Date the Rule was created. Read-only
Modified Indicates the most recent change to a Rule's information, whether modified manually or by an internal or external system event. Read-only
Creating a Rule

To create a new Rule, click the vertical ellipsis in the upper-right corner and click New.  Adjust the settings as required and select Save from the same menu.

Example Rules

The following are two example rules that cover the majority of situations we encounter:

Example 1 - Directory Service/Policy based Rules (iOS printing not supported)

  • Goal: Advertise specific printers to specific user groups.
  • Overview: Advertise "Staff" printers to "Faculty" Directory Group. 
    • Begin with a default printing rule.
    • Edit the name as appropriate.
    • Add Condition: Printer Tag = Staff
    • Add Condition: User Tag = Group: Faculty
    • Save the Rule

Example 2: Subnet based rules (iOS printing supported).

Note: iOS performs printer discovery prior to Presto knowing who the user is.  As such we will bind the subnet to a user type.  If you want to restrict printing so only specific users can print to a particular printer, add the authorized user groups to the Access field under Printer Settings. More details about printer settings can be found  here.

  • Goal: Advertise specific printers to specific subnets. A "student wireless subnet" is 192.168.5.0.
  • Overview: Advertise "High School Student" printers to 192.168.5.0 Subnet.
    • Begin with a default printing rule.
    • Edit the name as appropriate.
    • Add Condition: Printer Tag = HS Students
    • Add Condition: User Tag = 192.168.5.0
    • Save the Rule
Deleting a Rule

To delete a Rule, select the Rule, click the vertical ellipsis and click Delete from the same menu.

My Jobs

Within My Jobs is a personal Document Center, a feature accessible to every Authenticated user.  My Jobs is designed to be used in conjunction with Secure Release / Presto Station and lists all Print Jobs created by the User.  After printing to the Magic Queue printer a users will see all jobs pending release.

Held Jobs

While in a held state a user can do the following:

  • Release the print job to the printer.
  • Release multiple print jobs to the printer, by selecting one or more of the jobs
  • Modify the attributes of the print job.
  • Delete the print job.

Pending jobs not released within 24 hours are deleted automatically from the queue.

Station

The Station tab is the location to configure a Presto Secure Release Station and is only available on mobile devices.  Complete details can be found in  Presto Secure Release.

DNS

Implementing uDNS is simple, effective, and tremendously robust.  Only a single conditional forwarding record is required for all client devices with uDNS.  Only iOS clients require additional records.  Records are added to DNS servers that are answering requests from your client devices.  Any DNS infrastructure can be used for Presto. 

Note regarding DHCP 

Regardless of your DNS infrastructure, the ordering of the DNS servers handed out by DHCP must order internal DNS servers before external DNS servers. 

This example uses 8.8.8.8 as the IP address of the external DNS server.

  • Correct: 10.10.0.1, 10.10.0.2, 8.8.8.8
  • Incorrect: 8.8.8.8, 10.10.0.1, 10.10.0.2
Configuring DNS

Select the DNS tab in Presto, select your DNS server Environment and proceed to the appropriate section below.

Windows DNS

Add the conditional forwarding record to the DNS servers:

  1. Add the IP address of the primary DNS server answering client requests. This generates the Conditional Forwarding record.
  2. Copy the record and paste the record into a Windows Command Prompt on the DNS server with Admin rights.
  3. If supporting iOS, swipe and add the wireless subnet where you wish to discover printers on the client.  It is best to enter the CIDR e.g. 10.10.10.0/24

Repeat the above steps for each wireless subnet where you wish to support iOS printing.

BIND

Note: This is not intended to be a tutorial on how to set up a BIND server. We recommend referencing a definitive resource if required.  An example can be found  here

After configuring your BIND server and creating and testing your named config files and DNS Zone files, perform the following steps to enable DNS interoperability with Presto:

  1. Add the following lines to your named.conf.local (or equivalent) file. Replacing the IP address with that of your Presto server:
  2. zone "presto."
    type forward;
    forward only;
    forwarders { 10.10.241.21; };
    	
  3. Ensure there is a reverse lookup zone file for each subnet you wish Presto to service. Here is an example of a reverse lookup zone file with the required entries:
  4. @ IN SOA ns1.collobostest.com
    admin.collobostest.com. ( 
    ; Serial
    604800 ; Refresh
    86400 ; Retry
    2419200 ; Expir
    604800 ) ; Negative Cache TTL
    ; name servers - 
    NS records IN NS ns1.collobostest.com.
    ; PTR Records
    $origin 145.241.192.in-addr.arpa.
    93 IN PTR ns1.collobostest.com. ; 192.241.145.93
    101 IN PTR host1.collobostest.com. ; 192.241.145.101
    102 IN PTR host2.collobostest.com. ; 192.241.145.102
    $origin 0.145.241.192.in-addr.arpa.
    ; Required to support Presto
    b._dns-sd._udp IN PTR 0.145.241.192.dnssd.presto.
    lb._dns-sd._udp IN PTR 0.145.241.192.dnssd.presto.
    	
Unbound

Add the conditional forwarding record to the DNS servers:

  1. Add the IP address of the primary DNS server answering client requests. This generates the Conditional Forwarding record.
  2. Copy the record and paste the record into a Command Prompt on the DNS server with Admin rights.
  3. If supporting iOS, swipe and add the wireless subnet where you wish to discover printers on the client. It is best to enter the CIDR e.g. 10.10.10.0/24

Repeat the above steps for each wireless subnet where you wish to support iOS printing.
