I have two printers - DELL A940 and EPSON RX 595. I have found I can print to the EPSON, but not the DELL. When I try with the DELL, a window appears "AcroRD32.exe unable to locate DLBAGF.DLL. The computer locks and I have to use Task Manager to shut down the error windows and the pdf file. When I do this another window appears "Cannot load library DLBAPRP.DLL." ...I hope this helps. ...Also, believing the A940 driver might have issues I uninstalled and reinstalled. All other applications print successfully, with execption of Acrobat Reader.
