This article is for troubleshooting when the Mobility Print server is not able to discover any locally installed printers.
When this happens, you may see the message “Discovering your printers…” and after several minutes a warning banner will appear with the following message:
“We’ve been trying to discover printers for a while and haven’t found any yet…
Please ensure you have printers installed on your Mobility Print server. In the meantime, we’ll keep looking for them. This can take a couple of minutes for servers with many printers.”
Why does this happen? Mobility Print should be installed on a computer that already has several installed print queues. The software should detect those installed print queues before sharing them with users.
Ensure that at least one working print queue is set up for Mobility Print to find and publish.
- Windows: Click Start → Settings → Printers and then double-click on the Add Printer wizard and follow the steps.
- macOS: Click on the Apple icon → System Settings… → Printers & Scanners → Add Printer, Scanner, or Fax… and then follow the prompts.
Printers should appear in Mobility Print after just a few minutes.
If you are using masOS or Linux server, and are still seeing the message and printers are still missing in Mobility Print, then you might be experiencing a change made in the Mobility Print release version 1.0.3716 (Improved print queue filtering to avoid advertising inappropriate print queues. [MOB-1550]). In this case, follow the instructions below:
- Stop the Mobility Print service
- Go to the Mobility Print directory:
[app-path]/PaperCut Mobility Print/Data/Config
- Open the mobility-print.conf.toml file and set the value
MonitorMobilityManagedPrinters
totrue
. - Save the change and restart the mobility service . Printers should appear in Mobility Print after just a few minutes.
This setting was intended to reduce the possibility of duplicated printer advertisement on the network, if end users have mistakenly installed the Mobility Print server software. Setting this to true on your Mobility Print server will not reintroduce the possibility of duplicated printer advertisement.
