Hi,
We are trying to communicate with a GC420d printer through a web application. As per my understanding, over the network printing is not supported by this printer. Using Link-OS or Browser Print also does not seem to be as options since their support pages do not state this printer as supported. So it seems we are left with writing a Windows service to write ZPL to the USB serial port.
1. Is my understanding correct?
2. Is there a .NET or Java SDK which I can use to easily communicate with the printer? (check online status, send file to print)
3. Or is there any other way to print html/css through the printer?
Best regards,
Lihini
SDK to use with the GC420d printer |

Hi Lihini,
Here are some additional information regarding your questions.
Your understanding is correct. Zebra has not included GC420d in its testing yet with Browser Print. But it is a ZPL language printer. So eventually we could try to use Browser Print with GC420d over USB from a host.
We should be able to use our Link-OS SDK. The only recommendation is that we must use the ZebraPrinter interface, instead of using the ZebraPrinterLinkOs interface, because GC420d is not a Link-OS printer. For developing application for PC, the documentation folder we should use is PC(Java) or PC(.NET). For PC(Java) , the ZebraPrinter interface is at ZebraPrinter.
Not sure if you have seen this page - Zebra Web Printing Solutions, which contains a suite of information that you may be interested in.
Hope this helps.
Thanks,
GC420d does not have networking capability. It needs to connect to a host computer through USB or parallel interface in order to print. The printer itself can accept ZPL from host computer to print. Or, the host computer can send a general printer job to the printer, as if the GC420d was a regular printer. In this case, the GC420d driver needs to be installed on the host printer. You can check out the Link-OS Multiplatform SDK for developing an application on the host. Please be aware that this SDK is for Link-OS printers. The GC420d is not a Link-OS printer. However, the connection part of the SDK should work for USB connectivity with GC420d. The other advanced API in the SDK will not work with GC420d though. Hope this helps.
