Sorry if this has already been covered: Running Citrix PN Agent v9.1 and printing more than 1 page sometimes produces output to the printer: Upside Down and Backwards. I asked the User to remove the Toner Cartridge from the Laser Printer and put it back in right side up. (KIDDING!) :) At any rate, Citrix acknowledges this as an issue and has a NEW cpviewer.exefile that fixes the issue. However, cpviewer.exe is a clientside file, so in order to fix this issue, you have to update ALL your clients. Citrix is not sure that this patch will make it into the next ICA 9.2 client as the deadline for that client and updates to it, is approaching fast. In the meantime if you have users that call and state that printing is coming out upside down and backwards on multipage printing, you can get a supported patch from Citrix. This occurs using all Citrix UPD Printing in an all PS4 environment running the latest ICA client.
