Well since you specced A4 paper, did you have A4 paper in the tray? and 
of course, did it work? You may need to goto locolhost:631 with your 
browser and configure the options to suit your environment. Also, that 
uuid is unique to that printer, so it must be correct. else you'd 
collect a no such device error. An ls of /dev/serial/by-id might serve 
as a checking src. klipper, the better 3d printer driver, uses that to 
make sure its driving the right printer since usb has rather poor id 
mechanisms. from my printers output:
root@mkspi:~# ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec  3 01:17 
usb-Klipper_rp2040_E5D94D950DCD5658-if00 -> ../../ttyACM0
the E5D9..... is a unique to that chip serial number, no other rp2040 
has it.  So do all the stm32 controller chips.
Unforch that is not always true, as witnessed by this machine:
gene@coyote:~/src/klipper-docs$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec  7 11:39 usb-1a86_USB2.0-Serial-if00-port0 
-> ../../ttyUSB1
lrwxrwxrwx 1 root root 13 Dec  7 11:39 
usb-FTDI_USB_HS_SERIAL_CONVERTER_FTDHG45D-if00-port0 -> ../../ttyUSB0
where there aren't any chip serial numbers, but cups seems to have other 
ways of assuring its driving the correct device as a printer. One of 
those is actually driving a CM11A X10 home controller.

Probably more info than you need if the test page worked,
