Application does not detect networked printer

[jayjayseal]

Hi,

I have an issue with the application. If i try to print via USB, this works. But i want to use this using a RPI on a network. I can print to the printer using printf "lol" | lp -o landscape and this works by printing from a remote laptop to CUPS (Dymo 550) connected on a RPI (USB).

But the application (CLI or GUI) cannot find this printer and error's out with the following error. `$ dymoprint -qr qrencoded "qr_txt" No Dymo devices found (expected vendor 0x922)

• Vendor ID: 0x1d6b Product ID: 0x3

Ya, currently only printing via USB is supported. However thanks to the recent work of @tomers I think we're getting close to being able to work with networked printers.

If i try to print via USB, this works.

Does it work for you with dymoprint, lp, or both? I'm asking because we don't have confirmation that the 550 is compatible. See #44.

The Dymo SDK is a mess. But you can get it working with this SDK. Will post details later.

OK, here i go. (I have the lablelwriter 500 (usb only)

The reason behind me telling the SDK is a mess is the following:

• The SDK (according to Dymo support) is here: https://github.com/dymosoftware/Drivers
• The LW4xx Linux folder contains the ppd files for the Lablewriter 500 (someone already made a post about this here https://github.com/dymosoftware/Drivers/issues/2
• The installer does not compile correctly. For some users they have an error during compiling.
• The installer "forgets" to do a simple file copy for the raster/filter file.Copy the file (/LW4xx Linux/Linux/src/lw/raster2dymolw_v2) from the ZIP file to /usr/lib/cups/filter/

It will work for printing then.

If i use lp it works for printing, if i print a test page it also fit's it nicely on 1 label. dymoprint or dymoprint_gui gives the same error not being able to find the printer.

Dymoprint without modification won't recognize the 550 since it's not registered in our list of supported products.

You can do a development install and add it yourself. To get the device id which is the key in the dict, just run lsusb and you should see a line like:

Bus 001 Device 012: ID 0922:1001 Dymo-CoStar Corp. LabelManager PnP

Here 0922 is the vendor ID of Dymo, and 1001 is the device id for the LabelManager PnP.

For anyone referring in the future

@jayjayseal, I recently got A DYMO LavelWriter 550 printer, and hopefully I will be able to add support for that model in the near future.

I'm actually planning to buy a LabelPrinter 550. I hope there is support already.

In the meanwhile there is an official driver from Dymo themselves: https://github.com/dymosoftware/Drivers
