One of our customers keeps intermittently receiving Error 1958, Error Loading Printer Driver. I keep tearing my hair out on the same interval.

It can happen a couple times a day, printing successfully for hours and suddenly throw the error. In most cases, exiting and restarting the .EXE allows it to load and print.
Printer is on the network and set as Default printer, but even if the printer selection window is invoked and the printer selected, the error may still occur.

Googling found mention of spaces in the printer name causing this, but those were removed and the error still occurs.

Please help?

Chris.
