Printer Definitions Auto-created (Requires the client network) – Locally Attached – – Info stored in HKLM Locally Defined – Info stored in the user’s profile Autoconnected – Imported print queues assigned to users – Retained in the data store Remembered – Manually mapped from inside the session Retained in the users’ profile – HKCU/Printers/Connections – 4 © Citrix 2002 • Confidential

Printer Autocreation: Overview • Server Requests the printer information • Wfica indexes and enumerates the client’s printer information. • The ICA virtual channels are used to communicate with the server. 5 © Citrix 2002 • Confidential

Printer Autocreation: Client Side The basic questions that need to be answered…… – – – What port? Printer name? Which print driver? Answered by Wfica(ICA client engine) – – – Wfica 32 for win 32 clients(Win 9 x, Win 2 k, etc). Wfica. CE for Windows CE Wfica for Linux and Unix The public devmode structure contains the answers: [\JW-WIN 2 K-SVRHP Laser. Jet 4000 Series PS] --------------PRINTER_INFO_2 -----------------p. Server.

Printer Autocreation: Server Side The Metaframe XP policies can restrict printer autocreation Metaframe configuration (mfcfg. exe)can block printer autocreation at the listener. A list of drivers is maintained from the CMC. – – 7 © Citrix 2002 • Confidential Use ONLY the specified drivers Do not use the specified drivers

Printer Autocreation: Server Side Driver entries in the registry – – – HKLMSystemCCSControlPrintEnvironmentsWindows NT X 86. . Version-2 specifies Windows NT 4 drivers. . . Version-3 specifies Windows 2000 drivers Mapping files – – Wtsuprn. inf is read into IMA only during the MF XP install. Wtsprnt. inf is rewritten not appended as changes are replicated. Silent install NTprint. inf contains the file names required to install the win 2 k native drivers. – Can be modified by 3 rd party vendors – 8 © Citrix 2002 • Confidential

Printer Autocreation: Server Side FR 2 would only allow the print driver to be restricted OR mapped to another print driver (as shown above). FR 3 allows a driver to be restricted AND mapped to another print driver. 9 © Citrix 2002 • Confidential

Imported Print Servers Auto-connected Printers – – – 17 Do not use the ICA channel Use MS SMB printing The print job does not spool on the Metaframe server The printers do not have associated registry keys in HKLM only HKCU Print jobs might be slower to an autoconnected printer if the print server is over a WAN link from the Metaframe server. The print jobs cannot be throttled and do not use the ICA compression © Citrix 2002 • Confidential

Windows CE: Lab 2 Objectives The user will see the print job utilize CTXLPT 1: then compare with “Windows” printing. – Taking the subject a step further the CMC is used to push printer data down to the terminal allowing it to autocreate without user intervention. – This lab will provide the proof of function as detailed in the Win.

Follow the Print Job Graphics Device Interface – – – GDI ~ Windows based printing The user selects the document output for either the video card to display or for the print driver to render. The print job is formatted and converted by the print driver to be “displayed” to the print device. The resultant. SHD and. SPL files are sent to winntsystem 32spoolprinters folder. The. SHD and.

Questions: Question: Can LPT port redirection be disabled but the users still autocreate their printers? ? ? – YES. Autocreated “Windows Based” printers use the CTXCPM virtual channel. LPT port redirection use CTXLPT 1 and CTXLPT 2 channels. Can the Universal Print driver be used when printing directly to the print server? ? ? – 41 No. The Universal Print driver requires the client component PCL 4 RAST. dll to accept the print job. This is only found with the ICA client. © Citrix 2002 • Confidential
