lprinting to usb only

[wills721]

lprint -v usb://DYMO/LabelWriter%20450?serial=12111714255917 -m dymo_lm-450 "image-file"
lprint: Unable to start server: No such file or directory

Is it possible to use lprint w/o avahi? I do not need nor want network scans. I only need to print to a locally attached USB printer (shown above)

Thanks,
Will

First, you need to specify a sub-command to add a print queue for that printer.

Second, you can run lprint in a local-only mode that doesn't involve Avahi, just do:

lprint add PRINTERNAME -v usb://... -m dymo_lm-450

and then you can do:

lprint FILENAME

to print to the default (only) printer.

lprint add dymo -v usb://DYMO/LabelWriter%20450?serial=12111714255917 -m dymo_lm-450
lprint: Unable to access 'dymo': No such file or directory

I get this error?

[wills721]

You were missing a -d

lprint add -d dymo -v "usb://DYMO/LabelWriter%20450?serial=12111714255917" -m dymo_lm-450
lprint: Unable to start server: No such file or directory

But even this expects to run the server.

Yes, it runs the server in "standalone" mode.

What would be helpful to know is what operating system/Linux distribution you are using and what version of LPrint?

[wills721]

@michaelrsweet Ubuntu Core 22 -- sorry should have had that up front.

[wills721]

Latest version of Lprint. I pull it down from git and build it.

[wills721]

Seems lprint-server is just a script. Probably all I need to do is make sure this is in the path.

Why does it want to start Avahi if its a local printer?

Can pappl be built without avahi and dnssd? Hard to tell looking at the pappl configure. I was looking for a --disable-avahi or something along these lines and cannot yet find it. @michaelrsweet

The reason I want to do this is my application is an embedded application. A gateway. Deployed to health systems. The gateway is attached to the internet via mobile and is secured such that it will not find other devices in the same private network (private network over the internet). pappl does state it is usable for embedded applications but unless I can remove the network scans for a network printer (that would never exists) I may be unable to use this. @michaelrsweet
