When you say using all native drivers I assume you are installing the dirvers on Citrix server and letting them map when users log on 1:1 vs. any type of UPD. BUT I thought the promise with MPS4 was(with the caveat that some apps would still fall back to old way of printing if EMF file handling was not possible in the way required) that the EMF print file would be sent directly down to the client effectively doing away with the need to install any drivers on Citrix? -----Original Message----- From: Evan Mann [mailto:emann@xxxxxxxxxxxxxxxxxxxxx] Sent: Wednesday, November 30, 2005 12:08 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: How ready\stable is MPS 4? My farm is a clean install of 2003 SP1 with MPS4.0, no upgrades or anything like that. The farm itself is extremely stable. I have 2 zones with 2 servers per zone and a single WI server (I also use CSG). My only issues have been all printing related, but some were fixed by hotfixes (Print Manager crashing) and others appear to be related to an app I use that relies on a kernel mode driver. I use all native drivers, not the UPD, and I don't do any imported network printing, so it's pretty striaght forward on the printing end. I'm most likely going to deploy ScrewDrivers if my testing proves to solve some application specific printing issues. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Steve Parr Sent: Wednesday, November 30, 2005 11:50 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] How ready\stable is MPS 4? How far have things come? If stability is my number one priority should I stick with XP FR3? Also the real attraction for our company would be the apparent ease with which printing in theory is dealt with by MPS 4 - how much has this proven true in practice for others? Also I assume the upgrade path from XP3 to MPS4 is not smooth and possibly not even an option from what I recall reading on the topic last spring? Probably need to be on PS 3 to upgrade to 4?
