PaperCut – HP Chai Embedded Manual
2015-01-22
This manual covers the HP Chai embedded MFD setup. For general PaperCut MF
documentation, please see the PaperCut MF manual.
1
Overview
This manual provides an overview of the installation, configuration and operation of
PaperCut’s embedded software MFD (Multi-Function Device) solutions. Today’s MFDs are
smarter – they have touch screens and offer the ability to run applications directly on the
device. The goal of PaperCut Software’s embedded MFD solution is to leverage these
smart devices and to provide walk-up copier users with the same set of rich application
features provided in the print control area. These include:






Secure access to device functions (via Card Swipe, Username and Password, etc.)
End user authentication including integration with single sign-on environments
Monitoring and control of photocopying, scanning and faxing (quotas, charging,
allocation and logging)
Allocation of copying, scanning and faxing to accounts/departments/costcenters/projects
Release jobs from a hold/release queue (Secure & Find Me Printing)
Group based access control: Limit access to color copying or to the device as a
whole to selected user groups.
Highlights of the embedded solution include:
1.1 Consistency
The embedded solutions are developed in-house by the PaperCut Software development
team. This ensures that the copier interface is consistent with the workstation print interface,
meaning users only have to learn one system.
1.2 Integration
PaperCut is a single integrated solution where print, internet and copier control are all
managed in the one system. Users have a single account and administrators have the same
level of reporting and administration for all services. The embedded solution interacts with
the PaperCut server using a Service Oriented Architecture (SOA) and web services based
protocols.
1.3 Rate of development
PaperCut is developed under a release-often policy where new features are made available
to users as soon as they are complete. Unlike hardware based solutions, new versions can
be delivered to users regularly as software updates.
1.4 Vendor Neutral
PaperCut remains true to its vendor neutral stance. All embedded solutions are equal and
support all server OS’s including Windows, Linux and Mac.
1.5 Security
A large percentage of PaperCut’s user base is in Education environments where security is
important. All embedded solutions are developed with security in mind. Where security
objectives can’t be satisfied, any deficiencies are fully disclosed.

2.3.5 Disable HP Web Print
HP Web Print is a function of HP devices that allows users to upload files to the device via
the embedded web interface and have them printed, thereby bypassing PaperCut
accounting. Access to this feature should be disabled. (Note: PaperCut provides Web Print
as a core device independent feature).
This can be done in the administrator web interface on the “Settings” tab
o
o
o
o
o
click “Security” on the left side,
under “Device Security Settings” click “Configure”,
find the “Home Page” section (scroll down),
untick “Display Print Page on Information Tab” and click “Apply”.
This procedure may vary according to your specific model.
2.3.6 Disable the “Hold Off Print Job” setting
By default HP devices have a 15 second delay to start printing network print jobs when
someone is using the device (e.g. logged in to the device LCD). This can cause a 15
second delay to print jobs when a user releases a job from a hold/release queue.
This setting may be disabled either through the device LCD or through admin web interface.
To disable via the admin web interface:




Login to the device web interface as admin.
Navigate to Settings > Configure Device
In the tree view, open “Device Behavior” -> “General Copy Behavior”
Change the “Hold Off Print Job” setting to “Off”

Press “Apply” to save the changes.

2.3.7 Shorten Panel Timeout
To avoid ‘tailgating’ – i.e. users using the device on another user’s account, the device
should be configured to automatically log out the current user after a short time of inactivity
only. By default, this is set to 60 seconds, however 10 seconds is considered a good
compromise between security and usability.
To change the panel timeout, access the devices web page at http://<device-ip>/ and go to
the section Settings > Configure Device > Device Behavior (options will appear below) >
Inactivity Timeout. Change the timeout to “10” and click “Apply”.
2.3.8 Additional Network Security (optional)
The MFP communicates with the PaperCut server over the network (e.g. to authenticate
users or release print jobs). To provide an additional level of security, PaperCut may be
configured to only allow device connections from a restricted range of network addresses.
This ensures that only approved devices are connected to the PaperCut server.
By default PaperCut will allow device connections from any network address. To restrict this
to a subset of IP addresses or subnets:
1. Logon to the PaperCut administration web interface at http://<papercutserver>:9191/admin
2. Go to the OptionsAdvanced tab and find the “Security” section.
3. In the “Allowed device IP addresses” field enter a comma-separated list of device IP
addresses or subnets (in the format <ip-address>/<subnet-mask>).
4. Press the “Apply” button.
5. Test the devices to ensure they can continue to contact the PaperCut server.
2.4 Verify the successful installation and configuration
o
On the device screen you should see a login prompt asking for username and
password.
o
Log on to the PaperCut administration web interface at
http://<papercut-server>:9191/admin . On the Devices tab, you should see the device
listed under the name chosen previously.
o You should now proceed to configure page costs and other settings relating to the
device post-install testing
After completing installation and basic configuration it is recommended to perform some
testing of the common usage scenarios. This important for two reasons:

The user may log in with their identity number. Identity numbers
are convenient when usernames are long or cumbersome to enter.
For example, rather than entering a username like
‘john.smith.001’, it may be more convenient to enter an employee
ID of ‘1234’. See the PaperCut user manual for information about
user identity numbers, including importing identity numbers from
an external source.
Identity number ->
Require PIN
When a user logs in with their identity number, they must also
provide their associated PIN. This provides additional security for
identity number logins.
Swipe card
The user may log in by swiping a card (e.g. smart card, RFID and
supported by the device). See the PaperCut user manual for
information about user card numbers, including importing card
numbers from an external source.
Swipe card -> Require
PIN
When a user logs in by swiping a card, they must also provide
their associated PIN. This provides additional security for swipe
card logins.
Swipe card -> Enable
self-association with
existing user accounts
Users can swipe cards previously not used or registered at the
device with PaperCut and will be prompted for their username and
password. The swipe card can then be used at subsequent logins.
See chapter 4.2 for advanced configuration of this function.
Automatically login as
user
Specifies that this device should always automatically log in as the
given user. This option overrides all other authentication methods
Description of authentication methods

4 Advanced Configuration
4.1 Config Editor
The common configuration options for a device in PaperCut are available on the device’s
‘Summary’ tab, and are discussed in more detail in the Configuration section. This section
covers the more advanced or less common configuration options which are available via the
‘Advanced Config’ tab in the device details screen.
Config name
Description
extdevice.hp.message.wel
come
Specify two lines of text to appear on top of the login
screen in place of the default message. These can include
instructions on which username and password are valid for
the device. The value “DEFAULT” in this field will reenable the default text.
extdevice.hp.email.person
alized-sender
If set to “Y” and the email field of the user logged onto the
HP device has been populated in PaperCut, will set this
email address as the “From” field in the scan-to-email
function.
extdevice.hp.screen.small
Set to Y or N depending on whether your device has a
small (640x240 pixel) or large (800x300 pixel screen). In
most cases this will be automatically detected and the
setting will not have to be adjusted.
extdevice.hp.restricted.all
ow-multiple-login
Setting this to “Y” will allow users to log in and charge copy
jobs to a restricted account (user account or shared
account) if another copy job charged to the same account
is still in progress. This may cause cost overruns with
users going into negative balance.
ext-device-msg.cardassociation
Message to display when users are requested to associate
their swipe card with an existing user account. See chapter
3.2 for details. Specify “DEFAULT” for the default text.
ext-device.selfassociation-allowedcard-regex
Specify a regular expression that limits which card
numbers are accepted for associating swipe cards with
user accounts. See chapter 3.2 for details. Please contact
PaperCut support for help with regular expressions.
Defaults to “.*” (dot-star) which includes all card numbers.
ext-device.card-selfassociation.usesecondary-cardnumber
Select whether user self-association should occupy the
primary or secondary card number. It overrides the global
setting unless the keyword "GLOBAL" is specified. This is
useful when there is a mix of different non-configurable
card readers that read different numbers from an ID card.
Set to "Y" to use the secondary card number, "N" to use
the primary card number. Default: "GLOBAL" to defer to
the global configuration option.
ext-device.hp.limitreference.paper-size
PaperCut will deny copy access to restricted users who do
not have enough balance to copy. To determine if a user
has enough balance to copy and to compute the allotted

number of pages, a reference copy is required. By default
PaperCut checks if the user has enough balance to copy
one single sided Letter (North America) or A4 (worldwide)
page. In some situations it may be desirable to change
the reference copy, such as when the device allows
smaller page sizes like A5.
Default for ext-device. hp.limit-reference.duplex: N (No)
Default for ext-device. hp.limit-reference.grayscale: N (No)
Default for ext-device. hp.limit-reference.paper-size in

worldwide: A4
extdevice.hp.release.listformat
Change this to change the displayed list of print jobs
pending release to include details in addition to or in place
of the document name. Use the following place holders for
document details: %document% - document name,
%user% - username, %pages% - no. of pages, %time% time of printing, %cost% - cost of print job, %client% machine the print job was sent from. Example: “%user% %document%” would show jobs in the form “jsmith – Tax
Form.pdf”.
extSet to yes to show a warning message when users are
device.hp.release.show releasing documents while the device is still busy printing

considered not to be keeping the printer busy.
ext-device-msg.busyon-release
Message to display when above option is enabled. Specify
“DEFAULT” for the default text.
ext-device.card-noregex
See chapter 4.2 “Configuring Swipe Card Readers”
4.2 Configuring Swipe Card Readers
HP devices support the following keyboard emulating USB card readers:



Elatec TWN3 prox card readers
MAGTEK Swipe Reader Model # 21040110
RF IDEAS AIR ID Enroll Proximity Reader Model # RDR-7081AKU
Other keyboard emulating USB card readers may work, but should be tested prior to
deployment.
Supporting Card Reader authentication is as easy as:
1. Connecting a supported card reader to the device via the USB port (Note: On some
devices this is hidden under a sticker on the side panel).
Copyright © 2015 PaperCut Software International Pty. Ltd., All Rights Reserved.
21 of 28
PaperCut – HP Chai Embedded Manual
2015-01-22
2. Enabling Swipe card as an Authentication method under the device’s configuration in
PaperCut’s web interface.
3. Ensure the card number, as read by the reader, is loaded into the Card Number field
in the PaperCut database (or consider using user self-association).
Swipe cards contain numbers used to identify users according to the card number
configured in the User Details screen under “Card/Identity” number. Some readers report
information in addition to the number encoded on the card, such as checksums. PaperCut
can treat these cases in three ways:
Card Number Needs No Conversion

A typical case is the checksum being reported after the card number, separated by
an equals sign, such as in 5235092385=8. PaperCut can handle this case by
default; it will extract the number before the equal sign as the card number:
5235092385.
Regular Expression Filters

For some cases, a “regular expression” may be required that will filter the card
number from the complete string of characters reported by the card reader.
Documentation on regular expressions can be found on the Internet, e.g. at
www.regular-expressions.info.
o The regular expression must be fashioned so that the card number is
returned as the first match group.
o Usually one regular expression will be used for all the devices managed by
PaperCut; this must be entered in the “Config editor (advanced)” which you
will find on the Options tab under Actions. The key is called “ext-device.cardno-regex”.
o The global setting however can be overridden on a per-device basis: The key
“ext-device.card-no-regex” can also be found on the “ Advanced Config tab in
the device details screen. This setting will override the global setting unless
the keyword “GLOBAL” is specified.
o PaperCut developers will gladly assist in producing a regular expression
when supplied with a few sample outputs from your card reader. Please
contact PaperCut support.
o If you would like to write your own regular expressions, here are some
examples:
 Use the first 10 characters (any character): (.{10})
 Use the first 19 digits: (\d{19})
 Extract the digits from between the two “=” characters in
“123453=292929=1221”: \d*=(\d*)=\d*
Card Number Format Converters
In addition to extracting parts of the card numbers using regular expressions, converting
numbers from one format to another is a common requirement. For example a card reader
may report in hexadecimal format, while the number stored in the source (e.g. Active
Directory) is in a decimal format. PaperCut includes a number of inbuilt converters to assist
here.
Note: Many card readers are configurable - the number format can be changed at the
hardware level via utility or configuration tools. PaperCut’s software-level converters are

there to support card readers that don’t offer this level of configuration, or where a global
software-level conversion is a better choice. For example it may be quicker to do the
conversion in PaperCut rather than manually reprogram 100+ readers!
Like regex’s, the convertors may be defined on either a global (all devices) or on a perdevice basis.
To set globally:



Options -> Actions -> Config Editor
Search for “ext-device.card-no-converter”
Enter the name of the required converter (see table below) and click Update
To set at the device level:



Devices -> [select device] -> Advanced Config Editor
Search for “ext-device.card-no-converter”
Enter the name of the required converter (see table below) and click Update
Standard Converters
Convertor
Description
hex2dec
Convert a hexadecimal (base 16) encoded card number to
decimal format. Hexadecimal numbers usually contain 0-9 and AF. This will convert “946EBD28” to “2490285352”.
dec2hex
Convert a decimal encoded card number to hexadecimal format.
This will convert “2490285352” to “946EBD28”.
ascii-enc
Unpack an ASCII encoded card number string. E.g. given the
number “3934364542443238”, the ASCII code “39” is converted
to 9, “34” -> 4, “45” -> E, with the entire number resulting in
“946EBD28”.
javascript:<path> Advanced: Define a custom conversion function in JavaScript (see
below)
It is possible to chain or pipeline converters by delimiting with a pipe (|). For example,
ascii-enc|hex2dec will first unpack the encoded ASCII number then convert it to a
decimal.
Tip: Not sure which converter to use? Often trial and error is a good approach. After
presenting a card, the number will appear in an application logger message with conversions
applied (assuming the card is unknown to the system). Try different converters and inspect
the resulting numbers in the application log.
Using custom JavaScript
If the inbuilt converter functions are unable to meet the requirements, it is possible to define
your own function using JavaScript. This is an advanced exercise and it is expected that

any implementer be familiar with programming and JavaScript. To implement your own
converter:
Copyright © 2015 PaperCut Software International Pty. Ltd., All Rights Reserved.
24 of 28
PaperCut – HP Chai Embedded Manual
2015-01-22
1. Create a file text file [install-path]/server/custom/card.js
2. Define a single JavaScript function in this file called “convert” It should accept and
return a single string. Here is a trivial example:
function convert(cardNumber) {
return cardNumber.substring(3,10).toLowerCase();
}
3. Enter a converter in the form: javascript:custom/card.js
Tip: Check the file [install-path]/server/log/server.log when testing. Any
scripting errors will be displayed as warning messages in the log.
Tip: A Javascript script may also be included in the pipeline. For example
ascii-enc|hex2dec|javascript:custom/card.js
Other advanced notes


If both a regular expression and a converter are defined, the regular expression is
applied first. This means a regular expression can be used to clean up the input (e.g.
remove checksum or delimiters) before passing to a converter.
In some special situations a custom JavaScript implementation may not be enough.
For example there may be a requirement to use a 3rd party system to decrypt the
number. PaperCut includes an advanced plugin architecture that the PaperCut
Software development team uses to implement these advanced converters. Please
contact support to discuss development options and costs.

6 Known Limitations and Security
HP devices have some limitations that have an impact on functionality and security.
6.1 Interface responsiveness
The HP devices have very limited processing power and the interface in some areas such as
the login, seems a little unresponsive. Care has been taking to optimize this code, however
due to limitations in the framework some areas are not as responsive as we would like.
6.2 Account selection & other interface limitations
In an ideal implementation, users would be prompted to select and account when they click
the copy button. The HP framework however does not support custom screens in this area
– just a single message. This is why account selection is done via a separate button (acting
as a separate application). HP plans to address this in their new upcoming architecture.
It would also be nice to have support for custom logos and colors on the login screen. The
upcoming architecture will offer some options here.
6.3 Zero Stop when Copying
In an ideal implementation, PaperCut would be able to control exactly how many pages a
user can copy and always prevent the user from overdrawing their account. HP devices can
limit copying on a page count basis with the following limitations:
1. The copier does not report the paper-size, duplex or color information to the
embedded application until the job completes. So PaperCut must enforce the copy
limits based on assumptions as to which paper size, duplex setting and color setting
the users choose for their copy jobs. By default, the copier assumes A4 or Letter size
paper, simplex copying and color copying. This is a conservative setting for an
A4/Letter copier, i.e. actual copy settings will result in costs equal or below those
based on these assumptions. This can result in copying being denied to the users in
spite of sufficient credit. Configuration options are provided that allow an
administrator to configure a more generous setting with the implication that users
may overdraw their accounts.
2. When the permissible numbers of pages have been copied, the copy process is not
immediately halted but – due to the pipelined processing of pages – may continue for
another 3 or 4 pages, resulting in a small overdraw of a user’s account.
6.4 Simplex Pages in Duplex Jobs
Copying performed with the “duplex” setting – the output format set to “2-sided” – may
produce the occasional 1-sided page if the number of pages of a batch placed on the
document feeder is odd and the copier therefore only prints on one side of the final sheet.
While PaperCut’s print accounting counts these single final pages as simplex, in case of the
HP embedded solution such pages are counted as duplex.
6.5 Copy restrictions on restricted accounts
Users are prevented from logging in with a restricted account (user account or shared
account) if another copy job charged to the same account is still in progress. Copy jobs in
progress can be viewed using the “Job List” button on the device screen. Once the previous
copy job has finished, users can log in again and charge to the restricted account. This
behavior can be overridden using a configuration key, please see chapter 4.1.

6.6 Faxing
Faxes can currently not be tracked separately from scans and are currently logged and
charged as scans. This implies a single pricing scheme for both scans and faxes, i.e. the
cost per page would have to be the same for faxes as it is for scans.
7 Supported Card Readers
All keyboard-emulating card readers are supported as well as the HP Common Card Reader
(CCR).
