How can I add a printer under GhostScript + hpijs?

How can I add a printer under GhostScript + hpijs? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Hello everyone, please familiarize yourself with GhostScript and hpijs.
This problem has plagued me for several days.

A new printer is required for the company's products. The model is HP DeskJet D1668.

The model supported previously is the HP DeskJet workflow image, which is converted into a PostScript file through the filter and printed by the GhostScript. The driver used in the gs command is hpijs, the sDeviceModel is "DESKJET 990" (I don't know why D2568's product uses the 990 model. I asked my colleague to say it was a try ).

Now we need to add a printer of the HP DeskJet D1668 Model. I have tried many sDeviceModel and print options, some of which do not respond to the printer, some of which prompt that the Model does not exist during execution, and compiled the latest hpijs, put it on the board. I have never touched this thing before and do not know how to start with it.

I think the hpijs version currently used in the product is too low to support this type of printer, but the new hpijs program does not solve the problem, is it another resource (such as ppd, not put in the correct place ?)

Have you ever been a friend in this field? I want to help you analyze how to proceed in this case. Because the printing scheme under CUPS is not used, there are basically no Chinese documents on the Internet, and there are few English documents.

Thank you very much!
