Ok this is a wierd one and no mistake. Using PC's to network print to our several T & Z series HP Large Format Printers. We print hundreds of pages per day. Anyhow.... since a recent MS Windows 10 update killed network printing we've resorted to linking up the printers via USB. So far so good. All the printers print from Illustrator natively without issue. Well.... only one issue. All but one of the printers print multiple copies at any request. So if you need 2 copies of Job 76541 - you just load up the file - select 2 copies and 2 copies print out. Not so with just one printer. It only prints out 1 page - no matter how many copies you request. If you want to print a multipage document - it's ok with that as long as it's only 1 copy of it. If you want 2 copies - you have to print it twice. Every other printer is fine - multiple copies, multipage... everything is fine. So it's not the PC - it must be the printer, yes?
Unfortunately thats not quite true either. So if we print the same file Job 76541 (or whatever file gets printed) - from Acrobat - it'll print 2 copies or 3 copies or 7 copies no problems. If you print from InDesign - same file - it'll print 2 copies or 3 copies or 7 copies no problems. Photoshop - it'll print 2 copies or 3 copies or 7 copies no problems. Print from email/word/excel - all multiple copies work fine. So it must be Illustrator? But why would it work fine on different printers then? If it was the printer - why would it print multiple copies from different packages? Totally baffled.... Illustrator is the latest version 25.4.1 (64bit).
