Implementing AppSense print driver redirection without errors

Print driver redirection can make a remote desktop environment feel local, allowing users to print to an office device from an AppSense-managed session. It can also create failed logons, duplicate printers, long application launches, or jobs that disappear without a useful error. The cause is usually a mismatch between the endpoint, session host, policy, and printer driver rather than one faulty setting.

A reliable implementation begins with a clear print path. The endpoint may connect through Citrix, Microsoft RDS, VMware, or another virtual desktop platform, while AppSense controls the user environment and policy application. Each layer can redirect, remove, rename, or recreate printers. If two layers attempt to manage the same device, the result is often unpredictable.

Australian organisations face a particularly mixed infrastructure. A Melbourne head office may use centrally managed print servers, a Brisbane branch may rely on local network printers, and a regional site may operate across a slower WAN or an NBN connection with variable performance. A design that works in a metropolitan office can therefore fail when users move between sites or connect from home.

The safest approach is to standardise drivers, define ownership of each printer action, test with ordinary user permissions, and collect logs before making broad changes. Small pilot groups and version-specific documentation are valuable because AppSense products, Windows builds, and virtualisation platforms expose different controls.

Map the printing path before changing policy

Document how a print job travels from the user’s application to paper. Record the endpoint operating system, virtualisation broker, session host, print server, printer queue, driver type, and authentication method. Also note whether the printer is connected by USB, discovered through a local subnet, or published from a central server.

Separate the two common scenarios. In client-side redirection, the user’s local printer is made available inside the remote session. In server-side printing, the session sends the job to a shared queue or network printer. AppSense may preserve the user’s printer preferences, apply environment rules, or remove unwanted mappings, but it should not silently compete with the broker’s native redirection mechanism.

Create a simple ownership matrix before deployment:

• The virtualisation platform owns session printer redirection.
• The print server owns queues, permissions, and approved drivers.
• AppSense owns user-specific persistence, policy conditions, and cleanup.
• Windows owns spooler operation, driver loading, and local security controls.

This division prevents duplicate mappings. For example, if Citrix creates a redirected printer and Environment Manager creates a second connection with a similar name, users may see two queues while applications select the wrong default. Choose one authority for creation and configure AppSense to preserve or filter the result instead of recreating it.

Check whether printer names contain session identifiers, client names, or redirected-port details. Dynamic names are useful for troubleshooting but can interfere with profile persistence. A stable naming convention makes it easier to distinguish a redirected queue from a shared queue and to write precise policy conditions.

Standardise drivers and prepare the session hosts

Use a supported, signed driver that matches the operating system and platform architecture. Where the printing stack supports it, a universal print driver can reduce the number of vendor packages installed on session hosts. It may offer fewer finishing options than a manufacturer driver, so test duplex, colour, stapling, paper trays, barcode output, and accounting codes before selecting it as the default.

Avoid installing every model’s driver on every host. A large driver catalogue increases spooler complexity, patching effort, and the chance of version conflicts. Maintain a controlled package list, record driver versions, and remove obsolete packages through a planned change rather than deleting them while active sessions are using the queue.

The Windows Print Spooler should run under its normal service configuration, with current security updates applied. Confirm that session hosts can resolve the print server, reach the required ports, and authenticate to the queue. A successful ping does not prove that printing works; name resolution, SMB or print protocol access, RPC behaviour, and queue permissions still need validation.

Driver isolation is worth enabling where the Windows version and vendor driver support it. Isolation can stop a faulty third-party driver from terminating the whole spooler, although it does not correct an incompatible package. Test the isolation mode with multifunction devices and specialised forms because some vendor extensions rely on components that behave differently when separated.

For Australian sites, keep local queue design practical. A shared printer in a Sydney office may be close to the print server, while a user in Hobart may experience delay when a large job crosses a WAN link. Where policy and security allow, place queues near the users who generate the work, and apply retention or release-printing controls to avoid sending unnecessary documents across the country.

Build AppSense rules in a controlled order

Start with a baseline that contains no printer manipulation. Log on with a test account, allow the native platform to create the expected printer, and confirm that the user can print a small test page. Capture the printer name, port, driver, default status, and event logs. This baseline reveals whether a later AppSense action creates the fault.

Add one AppSense action at a time. Depending on the installed product and release, this may involve Environment Manager policy actions, session conditions, user configuration, or a dedicated print-management component. Use the administrative console and documentation for the exact version rather than copying settings from a different AppSense generation.

Apply conditions based on stable facts such as site, device group, session type, or security group. Avoid rules that depend on fragile text in a printer name unless that naming convention is centrally enforced. A user working from a laptop in Perth may need local printer redirection, while the same user in an office should receive a managed queue. Device location and connection context are usually better policy inputs than username alone.

Keep creation, persistence, and removal separate. First decide which printers should appear. Then decide which user preferences, such as default printer or duplex selection, should persist. Finally define cleanup for stale mappings. A removal action that runs before creation has completed can produce intermittent results, especially during a fast logon.

Use exclusions for service accounts, administrators, and test groups. Do not test solely with an elevated account because administrator rights can hide driver installation and permission problems. Standard users should be able to receive the intended queue, print a basic document, and use the required printer features without approving prompts.

If AppSense logon processing becomes slow after a printer policy is added, measure each action rather than disabling the complete configuration. The community’s guide to AppSense logon delays provides a useful comparison for separating policy processing time from Windows, profile, or network delays.

Test failures across users, devices, and sites

A proper pilot should include a managed office desktop, a home or mobile endpoint, a thin client if used, and a session host from each relevant image. Test a standard user, a user with delegated printer permissions, and a user who has never logged on before. Include reconnecting to a disconnected session because printer recreation often fails during reconnection rather than the first logon.

Validate more than a test page. Print from a browser, Microsoft Word, a line-of-business application, and a PDF reader. Test a small document and a larger file, portrait and landscape orientation, colour and monochrome, duplex, multiple copies, and any finishing options used by the business. Check that the selected printer remains correct after logoff, host change, reconnect, and profile refresh.

When a printer fails, collect evidence in a fixed order. Record the user, endpoint, session host, timestamp, printer name, driver version, queue status, and exact error. Then inspect the AppSense policy log, Windows Event Viewer, PrintService operational log, spooler state, and print server queue. Comparing a working and failing session often exposes a missing group membership, different host image, or inconsistent driver package faster than repeated policy edits.

A useful diagnostic checklist includes:

• Confirm the printer object exists inside the session.
• Check that the expected driver and port are attached.
• Verify the user can access the queue and printer server.
• Confirm the spooler accepted the job.
• Check whether the server released or held the job.
• Compare policy and session logs for creation or deletion events.
• Test with a basic universal driver if the vendor driver fails.

Treat timing as evidence. If the printer appears several minutes after logon, investigate network discovery, policy processing, and spooler timeouts. If it appears immediately but vanishes when an application starts, look for application-specific printer enumeration, profile actions, or a conflicting cleanup rule. A structured troubleshooting method is useful in technical work generally; even a 160-metre checklist illustrates how controlled checks can distinguish equipment, environment, and operating conditions.

Secure, document, and maintain the deployment

Printing can expose personal information, health records, financial data, and commercially sensitive documents. In Australia, the Privacy Act 1988 and the Australian Privacy Principles should inform printer placement, access control, retention, and disposal. The relevant obligations depend on the organisation and sector, but a redirection design should avoid sending confidential jobs to an uncontrolled home or shared office printer.

Use secure release printing where the business requires it, with a badge, PIN, or authenticated release workflow. Restrict queue permissions to appropriate groups and prevent ordinary users from installing arbitrary drivers on session hosts. Align the configuration with internal security controls and, where applicable, the Australian Cyber Security Centre’s Essential Eight practices, especially patching, application control, and privileged access management.

Document the intended behaviour in plain language. Include which platform creates redirected printers, which AppSense policy preserves them, where drivers are stored, who approves new models, and how stale queues are removed. Record exceptions for specialist devices such as label printers, receipt printers, engineering plotters, and multifunction machines with scan or accounting integrations.

Keep a versioned test record for every change. Note the AppSense release, Windows build, virtualisation platform, driver package, printer firmware, and policy export. When a vendor updates a driver or Microsoft changes print security behaviour, retest the complete path instead of assuming compatibility. A small regression suite can prevent a routine monthly update from breaking printing across a call centre or hospital department.

The AppSense Exchange community resources can help administrators compare product-specific configurations, discussions, and practical fixes. Use shared examples as references, then verify them against the organisation’s own AppSense version, access model, privacy requirements, and printer fleet.

Start with one office, a small set of approved drivers, and a representative pilot group. Capture the working baseline, introduce each AppSense rule deliberately, and retain the logs that prove how the printer was created and used. Once the pilot is stable, expand by site and session type, publishing the approved configuration and support procedure for service desk teams. Share tested policies and lessons with the AppSense Exchange community so other administrators can benefit from reliable print driver redirection.
