Ricoh Pcl5 Driver

[Karlyn Hemmerling]

Anyoneknow if a Ricoh MP 4055 will work with autocad? Installed the driver for the ricoh printer and whenever Autocad is started will not load until the print spooler is turned off or the print driver uninstalled.

How is the driver configured to print to the hardware? Is it going straight to the printer's IP address or is it going to a print server? Is it getting spooled locally first? If so, you might turn that option off to see if that makes any change.

There is no server in this environment. They have 6 or 7 computers and the print driver is installed on each computer. The driver is installed to an ip address. Autocad was already installed before this printer was installed. They had a xerox printer before this that worked fine they say. They are using REVIT 2018, Architectural Deskptop 2018 and AutoCAD MEP 2018.

I am waiting for some responses from specialists and I thank you for your patience. I looked at the NFO files and didn't see anything unusual. I am a little amazed that this is occurring because I don't think there are any calls to any print drivers during startup. Can you make a Screencast of how this is working/not working? How far into startup does AutoCAD get?

While I am waiting for the team to get back to me on their tests in Windows 7, they have asked if you might prepare a Screencast video that shows this behavior so that they might get a better idea of what is happening.

When it starts up does it show how far it is getting in the launch process? Does it look like it is doing a license check? I assume that since there is no server in the environment that it is looking to authenticate licenses with the Autodesk servers. Is there a firewall device that might be preventing access?

Are the CAD users printing to a PC3 file from within AutoCAD or directly to the Windows System Printer. If the Xerox driver is no longer necessary please verify that it is totally removed the workstation and then reinstall the Ricoh driver.

The xerox driver is completely gone and they are not printing to anything as they cannot get Autocad to open. Is there anything special that has to be done during installation for a printer that is not a plotter? I'm thinking it's just install on windows and then when autocad is open to pick that printer and print. I know the plotter has to be installed in the plotter manager.

I connected with your customer this morning and she indicated that she couldn't duplicate the problem on a couple of machines! She also indicated that some of the non-CAD machines were having problems with it installed too.

I suggested that she temporarily disable their anti-virus software and also to try a PCL5 version of the driver. She will also configure the driver to print directly to the printer (no spooling) and will also check the security settings to add Manage the printer for the Everyone group.

She says she is still having issues but hasn't tried all our steps yet. I also recommended sharing the printer from her computer that does not have Autocad and letting the autocad stations pick that printer to print from rather than installing themselves. I'll let you know when we find a permanent solution.

Any local user is able to overwrite program library files (DLLs) with own code as file permissions of file system entries are improperly set while a printer is added to the network. PrintIsolationHost.exe, of ricoh printers for Windows that has the SYSTEM privileges is the vulnerable component. The attacker would be able to execute library code as with administrative privileges by overwriting library files that are used in an administrative context., which in turn allows an attacker to escalate privileges to SYSTEM.

A directory named c:\ProgramData\RICOH_DRV\ is created during the printer setup when PrintIsolationHost.exe is processed and installs several files in this location, including several DLL files. Every user has full control over the installed DLL files as show below, because these files are writable:

The flag F means full access and the flag I means permissions are inherited from the parent directory. The inherited writable flag origins from a parent directory. The entire directory c:\ProgramData\RICOH_DRV grants full control to everyone:

Windows Group policies are a potential workaround. When group policies are used, there is a group policy to control installing printer drivers (Windows Settings -> Security Settings -> Local Policies -> Security Options -> Devices: Prevent Users From Installing Printer Drivers) and another group policy to control adding printers (User Configuration -> Administrative Templates -> Control Panel -> Printers -> Prevent addition of printers). When used, people cannot install drivers, respectively adding printers.
