Over the last 15 years I’ve tried pretty much every method of adding printers at logon there is – KIXTART script, VBS, Group Policy Preferences and Powershell. As part of speeding up logon, and investigating a weird issue with Windows 10 printers, I moved away from GPP and to Powershell shortly after we upgraded from Windows 8.1 to Windows 10.
The issue being – roughly 5% of the time, on random user/computer combinations, printers would take a long time adding and then fail to add, with a non-specific error message. My first go at this was a basic powershell script which had a hard coded list of location/printer mapping, and it would run the “add printer” command repeatedly until the error went away. (It always added fine on the 2nd go). The problem with this is that it’s a complicated script for technicians to update, and being a single threaded script the nice form it displays showing people what’s happening would freeze while it was working in the background.
My new script does the bulk of the work in background jobs – so printers add quicker (as it can do more than one at once), and the UI doesn’t lock up and freeze. More importantly, it uses Group Policy Preferences by reading the XML file generated and applies that – so technicians have the familiar interface for adding/removing printers from the script.
