Print Service Maintenance and Upgrade

DAY/DATE: Monday, February 18, 2013

TIME: 7:00AM-8:00 AM


SCS Printing (These changes will not take effect until after the maintenance period.)


During this maintenance, the current Windows print server, MONOLITH, will be upgraded. As part of this server upgrade, all Windows print drivers are being upgraded in order to provide greater printer functionality and higher print server availability.

What do I need to do after the upgrade?

  • SCS Domain Windows computers

    If you do not log out prior to this upgrade, and you print via MONOLITH.SRV.CS.CMU.EDU, most printer connections will continue to work and will automatically upgrade their drivers. If you do experience problems, please log out and back in to run the print driver re-installation script automatically.

  • Non-facilitized Windows computers

    If you print via MONOLITH on a Windows computer that is not a member of the SCS domain, please run the software installer SCS-Fix-Monolith-Printers-All.exe from MONOLITH.SCS.AD.CS.CMU.EDU in PC_DIST\SCS\Fix-Monolith-Printers\1.1.

  • Mac/Linux computers

    This upgrade should have no effect on printing from Mac or Linux computers.


As part of this upgrade, we are also configuring most supported SCS domain Windows computers to automatically re-install all printers connected to MONOLITH. This automatic re-installation will happen the first time you log in to your supported SCS domain Windows computer after the server upgrade. You should notice no interruption in service, but you will have new drivers for your MONOLITH printer connections, some of which may offer new and improved functionality and features.

Printer Drivers

Drivers for HP printers are almost all being replaced with the newer and now standard HP Universal Print Driver (HP UPD). This will provide true device-specific functionality, but it also means that the model of the printer will no longer be directly reflected in the name of its driver. Instead, the printer model name will be listed in the Comment field for the printer, typically available in the General tab of the printer Properties sheet.

In addition to better matching drivers to printers to expose more printer functionality, the new HP UPD also allows us to remove all kernel-mode printer drivers from the print server and take advantage of better driver and print queue isolation in the newer server OS. As a result, printing should be immune from disruptions currently experienced due to kernel-mode printer drivers and bad Postscript and thus more available.

Printer and Server Names

Printer names are being made uniform across platforms, and this requires removing hyphens from printer share names. Any printer share currently on MONOLITH which has a hyphenated name will be replaced by a new printer share with the hyphens removed, and any connection to a printer on MONOLITH with a hyphenated name will be replaced by a new connection to the non-hyphenated printer name. Connections to printers with hyphenated names will no longer work after the upgrade.

Also, the new preferred fully-qualified name for MONOLITH is due to changes in the clustering software providing high availability. Connections to MONOLITH as or will be replaced with connections to Other names, including and, will continue to resolve, but they are being deprecated as of this upgrade. Printing from non-CMU networks may also be broken if the remote network uses DNS caching not honoring our TTL on the name. There are several solutions to this problem, and the simplest is to use the SCS VPN to connect to the SCS network when using SCS network printers.

If you do have printing problems after the upgrade, please contact the SCS Help Desk at x8-4231 or send mail to
