Automatic tray selection from application

[jeib]

We have an application that prints both pre-cut labels and plain paper forms in the same function. We load our printers with the labels in tray 1 and plain paper in tray 2. When the system is first turned on, the application works perfectly, automatically switching trays to print to the proper form. However, at random points during the day, the automatic tray switching stops working, and all forms are printed on the pre-cut labels. This is totally unacceptable as the pre-cut labels are much more expensive than plain paper. After the problem appears, the only way to get the printouts on the proper form is to load only one label in tray 1 and then press the OK button to have the printer select from the other tray when the load tray light goes on. The only real solution that gets the system working correctly again is re-booting the system. Strangely, we have two other systems with the same OS and printer, and neither of those have experienced the same problem. 

What could possibly cause the printer/driver lose the ability to change trays upon request? Why is it only happening on this one particular system?

Thank you in advance for any help you can give.

Please try to configure all the trays with correct paper size & type from the printer control panel or EWS Page (web brower access).  This step will make printer hardware ready for using required media & it needs to be done only for the first time.

Next step should be selecting/applying the same paper size information in the document properties (page layout for Word).  The options to set correct document size might be different for differnt applications, but it is important to set it correct, to ensure that the print jobs is printed correctly.

Now while printing the document (with size defined as mentioned above), using the print window go to printer properties => Paper/Quality tab.  Here make selection of Paper Size, Source (Tray 1, 2, Manual feed etc.) and Paper type.  You may save this information as a quick set or printing shortcut for quick printing in future.

I hope printing the document as described above should directly make printer to print document without any manual intervention.

Ensure each of the tray is set to Paper size/type.

Hi Jeffrey,

My suggestion is to uninstall the printer software completely from you operator system and then resintalled again because this way the software driver will reconnected with all the system applications.

Seems to me that this is either a driver or application issue.

Let me know the results.

Thank you

I don't see how setting the tray properties would correct the problem we are having. If the tray settings were not correct, the application would never print correctly. Instead, we have a system that works for part of the day, then suddenly stops functioning properly. For a period during the day after the system is started, everything works as intended. Labels are pulled from Tray 1 and the other forms are pulled from Tray 2. Then for no apparent reason, tray switching stops, and everything is pulled from Tray 1. No settings are changed on the printer or in Windows. It's as if the driver is no longer passing tray change commands to the printer, or the printer no longer understands the command. (BTW, our tray settings are set correctly. Also, our application only allows us to point the different forms to the correct tray. All other settings must be set in code).

I was hoping that someone else had experienced and resolved the same kind of problem so that I had somewhere to start from.

I have tried re-installing the printer driver, and even downloaded the most up-to-date driver from HPs site. I agree that the problem sounds like a drive or application issue. What is making this hard to resolve is that we have two other systems running 64 bit Windows 7 and the same application (run from the same location on an application server, not separate copies), and neither of these systems are having the same problem. Mystifying.

Thanks for you response,

As an additional piece to add to this puzzle, the printer on the system in question is shared by another user for printing purposes, not using the same application. I can't see how, but is it possible that printing by the other user is leaving the driver/printer in this state?

Jeffrey,

That's a good piece of puzzle, my suggestion is to install the driver or software directly in each operator system, please do not share any driver because this actions create amny conflicts

Unfortunately, this did not help. My next step will be to try to eliminate any trace of the printer driver from the system, including registry entries, etc., and then re-install.

BTW, I downloaded driver installation software from the HP website and tried installing the driver with the most current version. I tried three different times to get the installation process to work, but all three times, the installation software crashed after a long period of time and deleted the printer from the system. I had to re-start and let the system re-discover the attached printer. Very disappointing.
