Discovering printers on your network
If you're a hardened print queue aficionado, you're spring to have some cuts and bruises from previous struggles trying to get the right printers showing upwardly for the correct people - or little effectually incessantly with impress queues and drivers.
With PaperCut Pocket and Hive, the product will practise as much of the heavy lifting as information technology can for you! Short of u.s. walking the floors and looking nether desks for lost printers, we have a few network tricks up our sleeves to discover USB and networked printers in your organization.
Have a expect through the behind-the-scenes details below on how PaperCut Pocket and Hive tin can aid find your printers, organize them and publish them seamlessly to your users.
The printer discovery procedure in a nutshell
The printer discovery activity is really made up of an elite team of processes. They're all part of the Border Node component that leaps into life when y'all install PaperCut Pocket or Hive.
The processes involved in printer discovery are:
-
Scanner process - the tool that hunts downwardly things that look similar printers on the network, or locally connected printers on your computer.
-
Probe process - once the scanner finds something that looks like a printer, the probe follows behind and sees what kind of printer it is, also as what it'south capable of (for instance, does it have a duplexing unit of measurement?).
-
Validator process - receives and checks out the data provided by the Probe by further interrogating the printers. Call back vivid-backlighting and intense questioning.
-
Reporter process - sends details about the newly found and verified printer up to the cloud.
-
Printer Registry - the 'printer database in the sky'. This deject component keeps track of which printers are associated with a specific arrangement, as well as all the capabilities and properties of the printers.
Scanner - Are there any printers out in that location?
The scanner'southward primary responsibleness in printer discovery is to identify sources that look similar printers on the device (Windows or macOS queues) - or somewhere on the network. There are two types of scanning:
Local queue scanner
The local queue scanner talks to CUPS (on macOS or Linux) or the Print Spooler (on Windows) to go information near the impress queues configured on the local mac or PC. Note that the local queue scanner as well moonlights every bit the 'probe' for local queue information. Slap-up.
Network scanner
The network scanner starts by picking up clues from local impress queues to prioritize which network addresses to scan - and and then scans the network for devices that look similar printers! The scanner then uses SNMP queries to bank check that the device establish is actually a printer, and if so, what type of printer it is.
Probe - Gather printer details
Luckily nothing too invasive!! The probe uses SNMP and IPP to collect equally much information as possible on the printer candidates constitute by the scanner. The probe isn't as well picky or judgemental about what it finds - all it's doing is gathering equally much data as possible to paw over to the validator.
Validator - Is it definitely a printer?
Just like humans, the printers are yearning for validation - luckily the validator steps up to help validate a printer, before reporting information technology to the deject. The validator uses SNMP or IPP requests to farther validate the previous findings, and to get together capabilities of the printer - can it do 2-sided prints? Is it out of toner? The validator needs to exist able to recall at least an IP address, MAC address, and make or model of the printer before it tin can say 'yep this is a printer'.
For locally configured queues on the Edge Node, the validator looks for the ConnectionURI (the connection string) in the local queue configuration (e.thousand. CUPS).
Reporter - Tell the cloud about the printers
After the validator gives the nod to each printer institute, the reporter sends the printer candidate (and all the additional SNMP or IPP data found) to the printer registry in the cloud. It'due south worth repeating hither that everything sent to the cloud - no matter how 'innocent' - is encrypted and sent over secure protocols. In this case, HTTPS.
Printer Registry - Making sense of all the printer data
The Printer Registry receives the printer candidate requests from the reporter and begins to piece together a 'definition' for each of the printers found. This definition includes the location (including the IP address for network printers or which machine it's connected to, for a locally attached printer), the brand and model of the printer, and its capabilities. From this information, it starts to build a big picture of the printer landscape.
It too creates a co-ordinator map, detailing which Edge Nodes have access to which printers. This is especially important for local printers (for example USB printers) - y'all tin can't print to a USB printer unless y'all're sending the job from the machine information technology's plugged into! However it'southward also important for network printers - organizations may take VLANs and other networking obstacles in place, which means that some printers are only attainable from certain workstations.
If the Print Registry doesn't have plenty information well-nigh a printer to build a 18-carat printer definition, it filters that printer out. It besides applies filtering to printers that shouldn't exist registered, like PDF queues (Virtual printers), Fax queues, test printers, PaperCut MF monitored impress queues, and PaperCut Mobility Impress URIs.
Deduplication / printer matching
Multiple Edge Nodes could report the same printers more than than one time, so a printer matching algorithm finds matches for already-known printers. Like a dating app of the printer world, it looks at qualities such equally IP addresses, ConnectionURIs, MAC addresses, hostnames, and serial numbers - and looks for that perfect match.
Registration
If the Printer Registry doesn't detect a match, (don't feel too bad for the printer! It ways it'southward a unique bit of treasure that we've establish!) then it registers the device as a new printer. Information technology chooses a new name for the device, based on the metadata it received.
Sometimes the registration process volition involve updating current printer data - for instance, if newly found data is discovered about a printer that is already known. In that case, the device information is updated with the newly found data.
Printer discovery frequently asked questions (FAQs)
Practice all the users have to run the discovery tool?
How often does the discovery process happen later on the kickoff install?
During working hours, the discovery process for locally-attached printers happens every 10 minutes and the discovery of network printers happens effectually once an 60 minutes.
Outside of working hours (9am-5pm in whichever timezone the Edge Node is located), discovery is less frequent (nosotros don't want to keep looking if there's no-one in the office!). Checking for local printers happens one time an 60 minutes, and checking for network printers happens every 12 hours.
I just renamed one of my print queues on my Border Node - how long volition it have to update in the admin interface?
I just installed a new printer - how long until it shows up in the admin interface?
I don't encounter my network printer listed - why not?
As you lot've seen above, PaperCut Pocket and Hive apply SNMP V1/V2 and IPP to discover printers. We also use your local printer queues as hints as to where to outset the subnet scan. For example, if you lot have a printer at address x.100.80.60, we will scan subnet 10.100.80.0/sixteen.
We also need ports for SNMP 161/162 and 631 for IPP (check out the System Requirements - Firewall ports page for more details). If these ports are blocked, we volition non discover a device. Ports might be allowed on a specific subnet but may be blocked from crossing onto other subnets, so if your printer is on another subnet that we cannot scan with SNMP or IPP ports, it'll remain subconscious to the discovery process.
I don't come across my local printer listed - why non?
Tin I add printers manually?
How are printers deleted?
How do you lot choose a name for a printer if someone has a printer defined as 'Closest printer' and someone else has information technology named as 'Library Basement'?
What if I use a private SNMP community string?
Does the discovery process back up SNMP v3?
