Some years ago I stumbled across this already and never found a fix for it. (stopped searching one day) Last week it happened again somewhere else and I got remembered. A new ink printer arrived in a small business environment. (all W10, decent PCs, all good) Works great. No problems so far. Now, there is this software that generates reports, that are "unnamed" when sent to the printer. (blank space instead of a document name when looking at the printer history) This results into an error. ("Error while printing") Its a HP printer now and it was a HP printer before. The HP printer before had no issues printing the unnamed file. Anyone ever had this happening to him as well ?
