OpenSpecimen supports printing for specimen and visit labels. On configuring printing, OpenSpecimen generates and writes the labels as CMD files on the file system. OpenSpecimen does not actually print the labels. It only writes the required data in the CMD file format understood by the printer automation software like Bartender, NiceLabel, etc. The print software can be configured to process these CMD files in an automated fashion.
OpenSpecimen print rules support is very flexible. It supports:
For configuring the printing into the OpenSpecimen please refer configuration section.
It also writes the JSON files to a database table which can also be used to print labels. The CMD files is the most preferred and used method. |
Below is the block diagram of the workflow:
OpenSpecimen works with any printer or scanner. The interaction with the printer is done via printer software which is explained below.
A: BarTender is most recommended. You are free to choose any other option as long as they support automated printing. Most of them follow similar approaches and should work with OpenSpecimen.
A: It doesn't matter on which server/desktop the automation software is running. As long as the automation software is able to read the files generated by the OpenSpecimen software, it could be on any server.
A: No. There could be a single printer for multiple users based on the group/network requirements. If using multiple printers that can be configured in the automation software to read the labels and send them to different printers as per the requirement.
A: One can create different rules based on the collection site, IP address. For each rule you can specify a different directory for property 'CmdFilesDir'. Then configure the automation software to link the different directories with an appropriate printer.
A: Any number of users can print. Rules are not based on user. Ignore this field, this is just a legacy from old print rules which we are checking if we really need it.
A: You might need to configure the same user to print to different printers located at different sites or buildings. E.g., there are two printers in two floors. Use Joe needs to print to first floor's printer when he is on the first floor and second floor's printer when he is on the second floor. This can be achieved using the IP addresses or ranges.
You can configure printing based on IP addresses of users. E.g. some sites assign dynamic IP addresses based on location of users. You can specify range of IP address. You can leave this blank if you do not want to use this feature.
A: No. It is just configurable keywords that you configure in the printer software and then use it in the rules. Example include whether label is printed for cap or slide etc
A: No. This is same as above. However, historically, this has been used to specify the path of printer label design template

OpenSpecimen uses print_rules.csv to decide on how specimen label content should be formatted and printed. The default rules shipped with OpenSpecimen prints specimen label, type and location. The printing rules can be customized based on CP, specimen type among other attributes as explained in below table.
This can be configured in OpenSpecimen from Settings → BioSpecimen → Specimen Label Print Rules
Please make sure that the customized rules file should be present on the OpenSpecimen application server.
Rules are matched in sequential fashion and stopped at first matching rule. Users are notified with an error message when none of the rules match specimen whose label is to be printed.
Field | Description | Example Values |
---|---|---|
CpShortTitle | Short title of collection protocol(CP). Default value is *, meaning any CP | Lung Cancer |
VisitSite | Collection site of visit. Default value is *, meaning any visit site | Arkansas Hospital |
SpecimenClass | Specimen class. Default value is *, meaning any specimen class | Example 1: Fluid Example 2: Cells |
SpecimenType | Specimen type. Default value is *, meaning any specimen type | Example 1: Whole Blood Example 2: Cryopreserved Cells |
Login | Login name of OpenSpecimen user who will be printing labels. Default value is *, meaning any user. | john@biospecimen.org |
IpRange | Specifies IP address range, using CIDR notation, of workstations of users who will be issuing print label requests. Default value is *, meaning any workstation | Example 1: 192.168.2.0/24 matches IPv4 addresses in range 192.168.2.0 to 192.168.2.255 Example 2: 2001:db8::/48 matches IPv6 addresses in range 2001:db8:0:0:0:0:0:0 to 2001:db8:ffff:ffff:ffff:ffff:ffff:ffff |
LabelType | Type of label depending on how and where it will be used e.g. Cap, Slide. If specified, value of this field is written to both database table and cmd file. The printer software can read this type and print labels accordingly. Default value is *, meaning don't care | Cap, Slide, or any other value that is used to denote type of printing the printer software needs to carry out |
LabelDesign | A name of the design template to use for printing labels. This value is of interest to printer software in deciding how label content should be arranged and printed. Default value is *, meaning don't care | Example: Cryovial Cap Label Name of design template configured in printer software. In this instance, name specifies label design suitable for printing labels to be used for cryovial caps |
LabelTokens | Specifies list of comma-separated attribute names of Participant, Visit or Specimen records that needs to be printed on labels. For detailed list of available tokens, please refer below table Default value: specimen_label,specimen_type,specimen_location | specimen_label,specimen_type,specimen_created_on will instruct OpenSpecimen to output values of following attributes of specimen record - label, specimen type and created on date |
Printer | Name of the printer. The printer name and their network addresses are configured in printer software to direct the label printing to appropriate printer | rosy, daisy rosy and daisy are symbolic names that can be configured in printer software to send requests to printers configured at IP address 192.168.2.110 and 192.168.2.220 respectively |
CmdFilesDir | Absolute path of directory on local filesystem that OpenSpecimen uses to generate cmd files. This should be a shared directory that is accessible to OpenSpecimen as well as printer software (like Bartender or Nice Label) Default value is * indicating do not generate cmd files | E:/Printer/CmdFiles/ |
CmdFileFmt | The format of data content in cmd file. Supported values are "key-value" and "csv". Default value is * indicating do not generate cmd files Current command line formats are tested with Bartender and Nice Label software. If you use some other software and face any issue, please let us know. | NOTE: The fields are case sensitive. Use "cvs" and "key-value". |
Lineage | ALIQUOTS, PARENT, or DERIVATIVE |
Once the print rules file is created, users can update OpenSpecimen to use new rules file as below:
Similar to specimen print rules file, visit uses visit_print_rules.csv to decide on how visit label content should be formatted and printed. The default rules shipped with OpenSpecimen prints vist name, date and collection protocol(CP) short title. The printing rules can be customised based on CP, site among other attributes as specified in rule.
Rule file format is same as specimen label rule file except two specimen related fields SpecimenClass and SpecimenType.
Users can create and update new rules file as below:
There are 2 options:
OS_LABEL_PRINT_JOB_ITEMS
in JSON format. The printer software can be configured to poll this table at periodic intervals for new rows, read data and send it to printer. Please refer /wiki/spaces/DEV/pages/4948040 for more detailsCmdFilesDir
rule variable value. The format of cmd file is as specified by CmdFileFmt
rule variable value. Printer software can configured to poll CmdFilesDir
directory at periodic intervals for new cmd files and print labels. Following table lists specimen print tokens that are shipped with OpenSpecimen. Use below tokens to include their corresponding value in printed labels

Adopters can implement custom print tokens by extending class AbstractLabelTmplToken
and providing implementation for following methods:
getName()
- returns unique name of token. Example: "specimen_requirement_code"getReplacement(Specimen s)
- returns string to be included in printed labelThe custom token implementation class needs to be registered with specimenPrintLabelTokensRegistrar
bean
Example 1: Label printed with barcode, specimen label and location
Example 2: Label printed with barcode and specimen label
Example 3: Label printed with site name, barcode and specimen label
Following table lists visit print tokens that are shipped with OpenSpecimen. Use below tokens to include their corresponding value in printed labels.
