I am unable to print to a Lexmark C782 printer

Question

I have been troubleshooting a print issue for 2 weeks. I have two iMac desktops. I am trying to print to Lexmark_C782 printers via ethernet. I have selected the printers through System Preferences>Printers and Scanners. When adding the printers I select the "+" sign, select the printer on the default tab. iMac finds the correct print driver (which I have downloaded and installed). I then select ADD and the printer is loaded into the print queue. I send a print job to the printer and a few things happen; 1, the print job disappears and never prints and the print queue shows nothing in the queue. 2, I will send a print job to the printer and the printer will display a 900 or 900.43  RIP software error or 3, on occasion it has printed (very rare). This same thing happens when using IPP and LPD. At this writing, I am unable to add printers using IPP, where as before I could.  IPP doesn't find the printers. Apple is unable to find the printer. I can open the terminal window and ping the printer. I can open Safari and brtowse to the webpage of the printer.
There has not been any changes to the computer.
Computer iMac
O/S X version 10.9.2
Processor 2.9 GHz Intel Core i5
Memory 8GB
Serial Number  D2*******8J3
Toubleshooting steps
1. Deactivated Appletalk on printers. I have read it is no longer supported, Apple uses bonjour
2. I have downloaded and installed the Mac OSX print driver from Lexmark but found that wasn't the latest.
3. I have made sure the latest print driver is installed. Version 11.2. Found that on the Apple website
4. I have innstalled the printer via IPP, LPD and bojour
5. I have 18 C782 printers
6. I have a network at my office
     16 workstations
     The workstation i am working on is connected into a switch that is connected into another switch in the closet
     All C782 printers are in one physical location with static IP addresses.
     They are all connected into a 24 port switch which is then connected to another switch in a closet
     Both switches are connected via different CAT 5 cables to the same switch in the closet.
7. I am trying to print from Adobe programs.
8. With the exact same setup I am able to print successfully from Windows 7 to all printers without any type of errors
All of the printers are  printing images, creative fonts on greeting cards (Adobe In Design, Photoshop, Illustrator, etc). Not sure if that matters but thought worth mentioning.
Any help would be greatly appreciated.

Answer 1

I talked to Adobe Support tonight and found this issue to be a known problem with some of the Adobe Cloud products when using older hardware, in this case the C782.
So, we found a workaround. Unfortunately the work around isn’t efficient and adds more steps to their normal printing routine
Open InDesign and create, modify delete the card
Select FileàExport
A window will appear. Pick the location you wish to save the file
Once the File is saved another window will appear
“EXPORT Adobe PDF”
An Export to Adobe PDF window will appear. Accept all defaults. MAKE CERTAIN “VIEW PDF
After EXPORTING” is CHECKED
Select Export
Once EXPORT is complete the file will open automatically in Adobe Acrobat
Most likely the screen will be very large
Select the + - sign at the top of the page to adjust the page size to view the image
Select FileàPrint
The Print window will appear
Select the printer from the drop down
# of COPIES is just below Printer
Select OK
I hope this helps anyone who is having similar issues
Thanks
