Dear Pascal, Thank you for your assistance. I just discovered the hidden control panel for CUPS on localhost/631 a few days ago, by accident when trying out a different Linux OS (Puppy Linux) which had an item in its main menu to Add Printer. Having seen that I tried it on my Ubuntu 14.04 64 bit system and the CUPS control panel listed the Epson Stylus S20, and found a driver for it, and assigned it to the USB port that it was plugged into. The printer then worked normally , as it used to before the upgrades, with a full menu of printing options. Since then I have moved the printer plug to another USB socket, and it has been successfully detected.
So the problem seems to have been that the printer was not automatically detected and set up by the gutenprint driver, but once I had found out about the manual installation, and used that, it now gets detected. If I had known about localhost/631 months ago I could have solved the problem, but Ubuntu does not reveal the existence of this to its users. Here is the output from the first part of the Debugging Printer Problems page that you sent me the link for, which detects the printer OK, so I cannot reproduce for you the steps which led to the problem of non-recognition of the printer. regards Tony Morton tony@tony-Inspiron-660s:~$ lsmod | grep usb usblp 22891 0 usb_storage 62209 1 ums_realtek usbhid 52570 0 hid 106148 2 hid_generic,usbhid tony@tony-Inspiron-660s:~$ tail -f /var/log/syslog Aug 15 14:00:11 tony-Inspiron-660s kernel: [ 280.129883] usb 3-4: SerialNumber: 4B4B36503035333355 Aug 15 14:00:11 tony-Inspiron-660s mtp-probe: checking bus 3, device 5: "/sys/devices/pci0000:00/0000:00:14.0/usb3/3-4" Aug 15 14:00:11 tony-Inspiron-660s mtp-probe: bus: 3, device: 5 was not an MTP device Aug 15 14:00:11 tony-Inspiron-660s kernel: [ 280.185753] usblp 3-4:1.0: usblp0: USB Bidirectional printer dev 5 if 0 alt 0 proto 2 vid 0x04B8 pid 0x0005 Aug 15 14:00:11 tony-Inspiron-660s kernel: [ 280.185796] usbcore: registered new interface driver usblp Aug 15 14:00:43 tony-Inspiron-660s anacron[906]: Job `cron.daily' started Aug 15 14:00:43 tony-Inspiron-660s anacron[2636]: Updated timestamp for job `cron.daily' to 2014-08-15 Aug 15 14:01:14 tony-Inspiron-660s kernel: [ 343.943741] usb 3-4: USB disconnect, device number 5 Aug 15 14:01:14 tony-Inspiron-660s kernel: [ 343.943928] usblp0: removed Aug 15 14:01:14 tony-Inspiron-660s udev-configure-printer: remove /devices/pci0000:00/0000:00:14.0/usb3/3-4 Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.296697] usb 3-4: new full-speed USB device number 6 using xhci_hcd Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.320318] usb 3-4: New USB device found, idVendor=04b8, idProduct=0005 Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.320324] usb 3-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.320327] usb 3-4: Product: USB Printer Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.320329] usb 3-4: Manufacturer: EPSON Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.320332] usb 3-4: SerialNumber: 4B4B36503035333355 Aug 15 14:02:20 tony-Inspiron-660s mtp-probe: checking bus 3, device 6: "/sys/devices/pci0000:00/0000:00:14.0/usb3/3-4" Aug 15 14:02:20 tony-Inspiron-660s kernel: [ 409.324615] usblp 3-4:1.0: usblp0: USB Bidirectional printer dev 6 if 0 alt 0 proto 2 vid 0x04B8 pid 0x0005 Aug 15 14:02:20 tony-Inspiron-660s mtp-probe: bus: 3, device: 6 was not an MTP device Aug 15 14:02:20 tony-Inspiron-660s udev-configure-printer: add /devices/pci0000:00/0000:00:14.0/usb3/3-4/3-4:1.0 Aug 15 14:02:20 tony-Inspiron-660s udev-configure-printer: device devpath is /devices/pci0000:00/0000:00:14.0/usb3/3-4/3-4:1.0 Aug 15 14:02:20 tony-Inspiron-660s udev-configure-printer: MFG:EPSON MDL:Stylus S20 SERN:- serial:- Aug 15 14:02:21 tony-Inspiron-660s kernel: [ 410.422042] usblp0: removed Aug 15 14:02:21 tony-Inspiron-660s kernel: [ 410.432257] usblp 3-4:1.0: usblp0: USB Bidirectional printer dev 6 if 0 alt 0 proto 2 vid 0x04B8 pid 0x0005 Aug 15 14:02:21 tony-Inspiron-660s udev-configure-printer: URI matches without serial number: usb://EPSON/Stylus%20S20?serial=4B4B36503035333355 Aug 15 14:02:21 tony-Inspiron-660s udev-configure-printer: No serial number URI matches so using those without Aug 15 14:02:21 tony-Inspiron-660s udev-configure-printer: URI of detected printer: usb://EPSON/Stylus%20S20?serial=4B4B36503035333355, normalized: epson stylus s20 serial 4b4b36503035333355 Aug 15 14:02:21 tony-Inspiron-660s udev-configure-printer: URI of print queue: usb://EPSON/Stylus%20S20?serial=4B4B36503035333355, normalized: epson stylus s20 serial 4b4b36503035333355 Aug 15 14:02:21 tony-Inspiron-660s udev-configure-printer: Queue ipp://localhost:631/printers/EPSON_Stylus_S20 has matching device URI Aug 15 14:02:21 tony-Inspiron-660s udev-configure-printer: URI of print queue: file:///dev/null, normalized: file dev null ^C tony@tony-Inspiron-660s:~$ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.
