Went to a customer complaining about various printing issues. Slow printing, not printing, printing garbage. This is on a Savin/Ricoh MP 4002SP.
First W7 computer I went to would not print from Chrome. Job would hit the queue and leave but never show up at the printer. A test print worked fine. Firefox and Internet Explorer print the same page without a problem. So chalked that one up to a Chrome issue.
Next computer would print a PCL test page just like a PS driver would to a non-PS printer. Even after clearing the spooler and resetting, and deleting all instances of any Ricoh or Savin related driver through the "Server Properties". Reinstalled PCL6 and still had the problem. Removed that driver and spooler and installed PCL5e. Problem solved.
Had about 10 other computers, W8 and W10, I did not play around with the PCL6. Got rid of...
