Where should the print server be?

Hello all!
Right now we have a cluster with two nodes for SAP (Node1: SAP & SAP PRD / Node2: Database) and all printers are installed on a different standard file server. Last week we realized that the file server is not the right place for SAP printer. If someone restarts the file server he unwillingly stops all SAP printing jobs. So we have two options now:
a) reconfigure the file server as a cluster with two nodes to get high-availability
b) put the printers on one of the SAP cluster nodes
Our system partner said we shouldn´t install the printers on the SAP system, it could slow it down too much. But I don´t think they thought about the two nodes. Would there be enough performance on one of the nodes. Maybe the printers could run on the database node or on the apllication node. How do you use printers and their queues? Or is
c) a dedicated print-server (as a two-node cluster)
a better idea? Thanks for any ideas

Hi Peter,
You have not given much info so I will have to make some assumptions
For printing, SAP firsts stores the data in the database via the spool work process then sends it off depending on the configuration of the printer access method. For local printing the data is then passed on to the spooler of your operating system where it is queued on the file system.
If you attach a printer directly to your database or dialog(application) instance(in SAP we call them instances not nodes then that means the management of your prints would also reside on the same system which is probably not a good idea especially if you start having problems with the printer. Also, you would be adding additional IO(through transferring data to file system spooler) and storage to the system which you probably could do without. Additional processing would also be required for managing the queued data. So yes, your supplier is correct in this case especially if your print jobs are large ones at times.
Personally, I would go for your final option c) but a) should also do fine.
Regards,
Nelis

Newbie cluster question: where does the admin server live?

Hello, I'm looking at clustering for our application where I work, and so I'm reading through the cluster-related documentation for 11g. I have a sort of an architecture question: where should the admin server be started? Hypothetically speaking, if you have two nodes for your cluster, would the AdminServer run on a 3rd box which sort of stood in front of the two nodes?
Thanks much -

The ideal situation would be for your admin server to be separate from the machines hosting your managed server. This allows you to control access to the admin server, eliminate the performance impact if you have the admin + managed on the same host, and limits impact if youir #1 host fails, etc.
But companies may be unwilling to invest in a distinct (3rd) host just for the admin server, especially if you have multiple environments ( prod, testing, dev, etc. ).
So usually the admin winds up sharing the host with a managed server.

Where are the print drivers found?

I have a Brother HL 2040 laser printer. THe Brother website has a version 2.2 driver for this printer. I downloaded and installed. When I add the printer I keep getting version 1.4 driver.
Can someone tell me where are the drivers found on my iMac?
Also I am trying to get this to print via a Linksys wireless print server. Do I use the ip address for the print server or the printer when adding this.
I tried using the print server IP but I get a "printer paused" issue. I think I need the new print driver.
thanks in advance for any help.

I have not gotten the driver to update to the newest version. I deleted the Brother Folders as mentioned in the replies, no joy. No matter what I do it ends up 1.4 not 2.0.
Version 1.4 worked OK for a USB connection, so I went forward with trying to get the network connection going. By trying every combination available I got it to work.
What HP jetdesk-socket has to do with my printer...escapes me. But that combination with version 1.4 driver works.
I will leave well enough alone.
I have 2 other computer to update to SL.....maybe.

HP Officejet Pro 8600 Wireless - Where are the printing shortcuts?????

HP Officejet Pro 8600 Wireless Printer
Windows 7
Where are the printing shortcuts?????
I just replaced a canon printer that died that had the concept of PROFILES, so that I could setup a PROFILE for each type of printing, i.e. 4X6 photos/documents/5X7 photos. So it was easy for our family to print, they would pick each setting.
Now with latest driver for 8600 there are NO way to save a set of settings for a printer. I have seen some old discussions on this but I just can't believe HP doesn't have this type of functionality in their drivers. I don't need the ePrint and all the other bogus stuff installed with the 8600 driver, but I DO NEED the ability to save different sets of printing options so I don't have to remember, borderless or not, landscape or not, etc and keep wasting photo paper/ink/regular paper with incorrect options.
Here is another posting with similar points -> Customers are NOT getting full print functionality. We don't care about the extra software, it is minimal. Full functionality includes the ability to create profiles for different printing situations so that the user can easily choose that profile (and therefore all the myriad settings for that profile). What HP has done is give us ONE profile, essentially, and every time you want to do something different, you have to change that ONE profile. How is that helping?
As I said, if I want to switch from a normal printing job (e-mail, web page, etc.) which uses my ONE setting, and then want to print a 4x6 photo, I have to remember to change at least 6 different settings. With the shortcut, I would select my "borderless photo" shortcut, and it would automatically switch paper trays, size, color, quality, you name it. Now you force me to change that each and every time.
If someone can explain why this is considered full functionality I would be extremely grateful.

Hello,
I am sorry you are having trouble with your print experience.
I am going to make some assumptions here, which could be wrong in your case, but might help others. Since you mention printing from Windows7 and ePrint in the same thread, can I assume you are trying to print using the HP ePrint driver for windows (www.hp.com/go/eprintsoftware) ? The ePrint driver also comes preinstalled on all HP laptops and pcs now, so maybe you made a recent pc purchase and therefore have the ePrint driver installed?
The goal of the ePrint windows driver currently has a lot less to do with providing the hundreds of print features and settings that the full featured, product specific print drivers provide. The goal is to enable customers to be able to print to any recent or new HP printer through a number of different connection paths from a single installed print driver / print queue. Once the ePrint driver is installed, printing with that driver will dynamically find direct network printers, cloud enabled printers, public print locations, direct wireless printers, etc., and create the correct print format depending on the print path taken. If the printer is ePrint cloud enabled and has a good internet connection, the printer and the pc do not have to be in the same location. For example, you can print from home to your printer at work. You can send photos of the kids to your mom's printer in another state, etc. The ePrint solution is also good for the traveling worker who just wants to send the occasional print job to the nearest network or wireless direct printer without having to find and install another print driver for each new printer. One driver, one queue and you can print to any recent or new HP printer.
The ePrint driver has a few important print settings that customers may want to use (copies, duplex, grayscale, etc). More may be added over time depending on demand.
BTW, because the ePrint driver does not have a ton of print settings to handle, the rendering of print jobs is as simple and efficient as possible and should not bog down your pc.
If you want all the bells and whistles in the print driver experience and just want to print to a single printer you can download and install the product specific print driver from hp.com
I hope that helps out a few people who may be wondering what the purpose of ePrint is!!
Good luck.
I am an HP employee, but these are my own thoughts and suggestions

Is the print server over-writing client printing preferences with defaults?

I'm testing a new 2012 R2 print server, and have set the printing defaults by clicking on the printer in Print Management and 'set defaults'. I used this to set things like double-sided printing etc.
When the printers are added to the test client workstations (manually, not by group policy), we then have to add in some details in printing preferences to authenticate that client to the printer. A valid access code, and print mailbox that tally with
the same settings on the printer. It's tedious, but that's what our current printers demand.
What's happening with the new 2012 R2 print server in testing is that it seems to be overwriting these authentication preferences and returning all the printing preferences to the defaults set on the print server.
It's likely that this is a feature or setting that I'm just not aware of, could anyone tell me please how to set those printing preferences as 'first time' preferences that can then be edited on the workstation, and persist?

Would you know of any resource where I could learn all the ins and out of printer management in 2012? A blog/a book/MVA course?
I assume you are using the General tab of the printer properties , then clicking Preferences to set the
Users defaults with the device specific data.
There are two ways to open up the Printing Preferences dialogue for shared printers that I'm aware of.
Open the Print Management console, open the print server, and printers. (1) Right Click on the printer and Set Printing Default or (2) Right Click on the printer, Properties, then from General Tab click Preferences.
Do changes made via both of those routes have the same affect regarding default settings that are given to the client or is there a difference between them?
I have been using method (1) above, but if there's any difference I'd be interested to know.
When it comes to adding the printers to the clients, there are also two options. (A) Control Panel, Printers, Add Printer, and add from directory. (B) In Windows Explorer, browse to the print server and double click the printer name to connect
it.
Is there any difference between those two routes? I had been using method (B), and then editing the preferences... when then seemed to be overwritten by the server defaults. Yesterday I used method (A) and so far the printing preferences for
the test clients have not yet been overwritten.

Architecture Q. : Where should the ODI Repository Database be installed ?

Hi all,
Where should the repository ODI database be installed
=> on the same server as the source database one or ?
=> on the same server as the target database one
Thanks for your answers
Edited by: Meapri on Feb 26, 2009 6:59 AM

Hi Shib,
Maybe I could agree with you if you only use ODI for DW, for instance.
If you think about data integration, no matter what kind of system, even at transactional system, or datamart extract/load the concept of "source and target" can be any of the RDBMS at company.
What I'm defending is that in a complex environment, where ODI is the company *"data veins"*, the concept of source and target became complex too and, in my opinion, is not possible to decide where the repository should stay just by the use of those concepts.

Where should the ODI agent be

Where should the ODI agent be. In Source server or target server
app

Well when we say the Target Location we generally means the Target Database or the Data warehouse location , since data needs to pass through the Target Server (target Database ) ,as i have mentioned before in my reply the target Tables or Database is how generally where the C$ ,i$ and various $ tables and also finally the Insert /Update takes place at the Target. When the data is there in one server ,the time for the agent to move data gets reduced and thus saved time and Efficiency.
although this is not an hard and Fast rule its just an advisable practice. There are some Architecture where the ODI is installed in another Server and the Target Database is located in another Server. Some of them goes for creating the Agent at the Server where ODI is installed and so ODI communicates back and forth to in both the Server for its ELT operation.
Again there are some who creates Agent even in the Source and Target , when there are huge loads needs to be fetched and processed.
coming back to your question when you my machine , are you talking about your personal Desktop or Laptop Machine . ? In that case i guess your Target and Source and again the Agent created will be once Machine itself.
Let me know if you require any more information or clarification .

Where did the print setting "Rewrap message to fit" go in Mail 7?

Where did the print setting "Rewrap message to fit" go in Mail 7?
All text prints too small. Settings for font size haven't changed and the emails print out much smaller than the view settings.
I don't see the options for "Rewrap message to fit" or "Keep fonts the same size".
Suggestions?

I have the same problem. Text and the info with the "To" header all prints very small. I also cannot find the controls described. Just updated to Mavericks, never had problem before this. Same printer, and problem also occurs on another different model printer I tried for a test.

What is the print server username and password?

I am trying to install a Kodak ESP 5210 printer.
I set up the printer - it is on my wireless network.
I installed the Kodak printer software - it too installed correctly.
At the final step I need to "add printer" I click + in the printer window.
I then choose the kodakaio directory under "Windows".
I then choose kodakesp5200_00.
I am asked for the print server username and password.
I tried my log in password with just my first name in lowercase as username as this field was filled out by default.
I tried lots of different things, including no password, but the printer "Add" button never becomes not greyed out.
Would appreciate help. Kodak were no help.
I have pinged the printer successfully so its definitely on the network.
Thanks

Because nothing is listed in the default printer directory

Where is the printer head located on the MP600?

Where is the printer head located on the Canon MP600 and how do I remove it? I have had my printer for over 7 years with absolutely no problems! Then, yesterday, after I replaced an ink cartridge, it would not print at all -- keep getting the message "Wrong Printer Head - Replace Printer Head" - I removed all the cartridges and re-inserted them, but that did no good. One suggestion I found on-line said to remove the printer head and re-install it -- Where is it located???

Hi mjomeara,
To reseat the print head in the unit, please follow the steps located here. Once the print head is reseated, please turn off the printer, unplug the power cord and leave it out for at least 10 minutes, then plug it back in and turn the printer back on. If you still receive the print head error, the printer will require servicing. Please call or email us using one of the methods on the Contact Us page for further assistance.
