Prints only a Single Copy when Sending Multiple to Sharp-MX-3071 about cups-filters

Hi @biicwlim ,

I'm sorry for late response - would you mind trying adding *cupsManualCopies: true into your PPD file, reinstall the printer with it and try printing copies?

Your printer supports printing of application/pdf, so CUPS expects it can handle copies - which does not seem to be true.

Per OpenPrinting/cups#787 (comment) such printers (IPP Everywhere printers which claim PDF support but don't support copies) are seriously broken and it would be great if you reported it to the printer manufacturer. We don't plan on supporting workarounds for such printers in CUPS.

However, 'driverless' is PPD generator from cups-filters and libcupsfilters, so the final decision is on their author. I'll reassign the issue to cups-filters.

Sorry, I'm just seeing your reply, and I've tried too many other things since then to probably be able to debug the original issue.
I did find this discussion, relating to what appears to be the base issue. https://unix.stackexchange.com/questions/716784/how-to-reset-the-printing-system-cups
I don't know if it's cups related or a Ubuntu/Mint specific issue, but things print great out of the box or in a live session, and then I can't ever get everything working right again after a restart.
Since the issue seems to have morphed and might not be Cups at all, I'll mark it as closed.
