Printer Keys

The following keys are available in the Printer Configuration File. The keys and their values are stored in SEAL-specific MongoDB.

The printers are imported, exported and managed via easyPRIMA.

Hint - bos2gyros

With the bos2gyros command line tool, the printer configuration provided by the Driver Database from SEAL Systems (DDB) is mapped to the configuration format known to PLOSSYS Output Engine.

Units

Values with time specifications are specified in the following time units:

  • seconds (s, sec)

  • minutes (m, min)

  • hours (h, hr)

  • days (d)

  • weeks (w, wk)

  • months

  • years (y, yr)

Example - with time units

2 hours and 30 minutes: 2h30m

4 minutes and 2 seconds: 4m2s

Top Level Section

The top level section of a printer configuration file contains the following keys and sections:

    Horizontal alignment right, vertical alignment bottom

  • lefttop

    Horizontal alignment left, vertical alignment top

  • righttop

    Horizontal alignment right, vertical alignment top

Default: 'center'

printer Key

printer specifies the name of the output device in the Output Engine system.

Caution - allowed characters

The printer name must not contain UTF-8 or apostrophes. Although the printer will be imported, jobs cannot be processed via this printer.

The key is mandatory.

Available values: String

Default: none

connection Key

connection specifies the URL of the printer connection. The URL includes the transfer protocol, the printer name and the port number. If printer failover or load balancing is needed, use Virtual Queues.

The key is mandatory.

Available values: String

  • connection:<protocol>://<printer_name>:<port>/<queue_name>?<options>

Default: none

Available values for <protocol>: String

  • command
  • http
  • https
  • ipp
  • ipps
  • lpr
  • pjl
  • socket
  • virtual

Available values for <port>: Integer

Default:

  • 515 for lpr
  • 9100 for socket and pjl
  • 80for http
  • 631for ipp
  • 443 for https and ipps

Available values for <queue_name>: String

  • specifies the name of the printer in the spooler (mandatory).

http, https, ipp, and ipps all use the IPP protocol to transfer the job to the printer. https and ipps use TLS encrypted connections to the printer. Currently, printer certificates are not validated in standard installations.

Available options - only for lpr:

  • stream specifies whether the data is streamed. With stream=false, jobs can be output via LPR to a Windows Print Server.

Available options - only for pjl:

  • checklevel specifies the level of the PJL protocol supported by the printer:
    • checklevel=full specifies full PJL support. This is the default if no check level has been specified.
    • checklevel=sync specifies restricted PJL support using the @PJL ECHO message.
    • checklevel=none specifies no PJL support. This is equal to the socket protocol.

Available values: Boolean

Example - printer connection with socket

connection: socket://myprinter:9100

Example - printer connection with lpr

connection: lpr://myprinter:515?stream=true

Examples - printer connection with ipp/ipps or http/https

connection: ipp://myprinter:631/
connection: ipps://myprinter:443/
connection: http://myprinter:631/
connection: https://myprinter:443/
connection: ipp://myprinter:631/ipp/
connection: https://myprinter:443/ipp/printer/

Most printers work with the first four examples. Some, however, require a path to be set like in the last two examples. The most common paths are ipp/ and ipp/printer/ as shown in the examples.

Example - printer connection with pjl and restricted PJL support

connection: pjl://myprinter:9100?checklevel=sync

Example - printer connection with command

- printer: printercmd
  connection: 'command://'
  server: spooler1
  command:
    cmd: /code/bin/testout.sh
    args:
      - -printer

queues Key (virtual Section)

queues specifies a list of target queues for failover or loadbalancing.

The key is mandatory if the queue type is failover or loadbalancer.

Available values: List of strings

Refer to the example in the virtual section.

Default: none

Caution - all queues

With a virtual failover queue, all queues involved have to be configured in PLOSSYS Output Engine. Otherwise, the jobs for the virtual queue will terminate as erroneous.

routes Key (virtual Section)

routes specifies a list of routes. Each route contains a condition and a queue.

condition is a string which is interpreted as JavaScript code returning a Boolean value. Hereby, the job object can be used for the job to be output and the origPrinter variable contains the name of the original virtual printer. For a detailed description of the job object, refer to job object used in the route condition of a virtual queue.

queue is the target queue to be taken if the condition returns true.

The key is mandatory if the queue type is router.

Available values: List of objects containing a condition and a queue

Default: none

Example - routing by size, color and duplex

- printer: myRouterQueue1
  connection: 'virtual://'

      type: 'router'
      routes:
          # Color jobs go to printer1
        - condition: job.COLOR_MODEL[0] === 'COLOR'
          queue: printer1
          # Duplex b/w jobs go to printer2
        - condition: job.DUPLEX === 'LONG_SIDE'
          queue: printer2
          # All other jobs go to printer3
        - condition: true
          queue: printer3

Example - routing by size and color

- printer: myRouterQueue2
  connection: 'virtual://'
  template:
    virtual:
      type: 'router'
      routes:
          # Color jobs with a size less or equal DIN A4 go to printer1
        - condition: job.getMaxPage().le('a4') && job.COLOR_MODEL[0] === 'COLOR'
          queue: printer1
          # Gray-scaled jobs with a size less or equal DIN A4 go to printer2
        - condition: job.getMaxPage().le('a4') && job.COLOR_MODEL[0] === 'GRAY'
          queue: printer2
          # Jobs with a size larger than DIN A4 go to printer3
        - condition: true
          queue: printer3

Hint - relevant order

The order of the specified routes is relevant due to the first match will be used. For example, with the following configuration, a DIN A4 color job will be output to printer1, although printer2 would make more sense.

- condition: job.COLOR_MODEL[0] === 'COLOR'
  queue: printer1
- condition: job.COLOR_MODEL[0] === 'COLOR' && job.getMaxPage().le('a4')
  queue: printer2
- condition: true
  queue: printer3

After changing the order of the routes, the job will be output to printer2.

- condition: job.COLOR_MODEL[0] === 'COLOR' && job.getMaxPage().le('a4')
  queue: printer1
- condition: job.COLOR_MODEL[0] === 'COLOR'
  queue: printer2
- condition: true
  queue: printer3
strict Key (virtual Section)

strict specifies if the router will stop processing the list of conditions after having found the first match or process the whole list of conditions.

The key is optional.

Available values: Boolean

  • true

    The router will stop after the first match and add only the found queue to the queue list.

  • false

    The router will process the whole list of conditions and add all matching queues to the queue list.

Default: false

Example - strict router queue

- printer: myRouterQueue3
  connection: 'virtual://'
  template:
    virtual:
      type: 'router'
      strict: true
      routes:
          # Jobs with a size less or equal DIN A4 go to printer 1
        - condition:job.getMaxPage().le('a4')
          queue: printer1
          # All other jobs go to printer2
        - condition: true
          queue: printer2

tolerance Key

tolerance specifies the tolerance for selecting a format, unit is in default mm. The key is only used for printers with configured ppd.

The key is optional.

Available values: String

Default: '6.5'

Hint - output Letter onto A4 and vice versa

Contrary to PLOSSYS 4, PLOSSYS Output Engine will not automatically print Letter format onto A4 and vice versa. If available, PLOSSYS Output Engine will use the next larger format instead. If no larger format is available, PLOSSYS Output Engine will act the same as PLOSSYS 4.

For many printers you can specify in their settings, if Letter and A4 formats should be treated as the same. If your printer has this option, no additional changes have to be made in PLOSSYS Output Engine. If this option is not available, you can do the following:

Increase the tolerance value to 7.5 to always output Letter onto A4 even if larger formats are available.

Increase the tolerance value to 13.3 to always output A4 onto Letter even if larger formats are available. When doing so, the scaleMode should be set to fitPrintArea, otherwise too much content will be lost.
