Issue
It has been reported that HP Bidirectional Channel components (cioum32.msi /cioum.dll or cioum64.msi / cioum.dll
) could be the potential cause of various performance related issues within stand-alone print servers, Windows Cluster Server, Citrix, and/or Terminal Server environments resulting in 10 minute delays during driver installation, intermittent print spooler crashes, performance issues, CPU spikes, etc. CIO MSI does not get installed if a user with non-admin rights attempts to install the driver. The driver will attempt to install the MSI multiple times [5 times, with an interval of 2 min between each try] without checking the access permission. This multiple execution causes a delay with the installation and will launch multiple instances of the MSI installer which can contribute to the cause of poor performance on the server.
The Windows Event log will usually indicate a reference to: 32/64 Bit HP CIO Components Installer. Product Version: X.X.X. Product Language: XXXX.
This issue may manifest itself with the Universal Print Driver and also current product discrete PCL 6, PCL 5, and Postscript drivers which are bundled with cioumXX.msi/.dll components. An update has been made to the cioum.dll component which will be released in UPD 4.7.2 which should resolve the majority of these circumstances. As there are numerous configurations regarding UPD and discrete drivers, please refer to the following workarounds for assistance:
