Can these be delayed to start after bootup?

HI fixit7,
is your printer already fully set-up? .
Yes, printers are setup.
Then leave the printer powered off and only switch it on when needed, I personally don’t know of any other way myself!. Is it causing you a problem?, if so; which?.
printer only comes on when needed.
I will accept the extra 32 secs of boot time.
Maybe try changing your software sources download location and updating again, it may solve the long boot time problem?.
My boot times are good.

@fixit7 fixit7 So, it’s a systemD service that is triggered by udev.
Udev rule is in /lib/udev/rules.d
Can you give me the output of
ls /lib/udev/rules.d
Nevermind, found it after starting ubuntu mate 17.10 in a VM (no access to my computer right now).
[code]$ cat /lib/udev/rules.d/70-printers.rules
ACTION==“add”, SUBSYSTEM==“usb”, ENV{DEVTYPE}==“usb_device”, ENV{ID_USB_INTERFACES}==":0701??:", TAG+=“udev-configure-printer”, TAG+=“systemd”, PROGRAM="/bin/systemd-escape [email protected] %p", ENV{SYSTEMD_WANTS}+="%c"
ACTION==“remove”, SUBSYSTEM==“usb”, ENV{DEVTYPE}==“usb_device”, ENV{ID_USB_INTERFACES}==":0701:*", RUN+=“udev-configure-printer remove %p”[/code]
That is the udev rule that runs when you add/attach a usb printer.
It is starting this systemd service:
[code]
$ cat /lib/systemd/system/[email protected]
[Unit]
Description=Automatic USB/Bluetooth printer setup (%i)
Requires=cups.socket
After=cups.socket
[Service]
#Type=simple
Type=forking
GuessMainPID=true
ExecStart=/lib/udev/udev-configure-printer add %I
It’s setting up the printers on boot.
Try to launch it 5 seconds after light display manager. Change After=cups.socket to
After=lightdm.service
and add next to the end of /lib/systemd/system/[email protected]
[Install]
WantedBy=graphical.target
If that doesn’t work I’m not sure what will.
I tried this but no change.
I really appreciate your help. I learned a lot.

Using this, boot reduced from 32 secs to 21 seconds.
Thanks so much.
