How to create patterns that can distinguish between printer models I scan

[Odd-Laurits Andreassen]

We have many printers that are different models. I need to be able to have pattern for almost every model as OID is not the same on all models for serialnumber/model/Vendor. 

Have tried to make several patterns for different printers with different OIDs. The last printer pattern that is run overwrites the printer information.

I need help understanding how to get the pattern to only run for specific Model.

Hi, @Odd-Laurits Andreassen 

It's very abstract question, without examples, how names can look like.

Of course, I can advice you to use https://regex101.com/ and chatGPT, but if you want us to help, we need more input information. Regexp depends from names. No names = no regexp :)

Hm, so, you're asking not for regexp pattern, but for pattern for discovery.
Honestly to say - not a good specialist in it, but you can try this code. It's made with latest model of openai and looks like code, that can solve your problem. Can't check it though

Hi. Thank`s! This made my day. 

// Check if the model is "C792"
if (model == null || !model.Equals("C792", StringComparison.OrdinalIgnoreCase))
{
// Not the target model, exit the method
return;

and where the code is in the pattern. I will try this :)

Hi. Sorry for the lack of information. 

We have Lexmark printers and some of the models:

CX735adse
MS521dn
MS811
C792
CX510de
CX635adwe

C792

The pattern I am using is starting like this and i don`t understand where to put the code that makes this pattern to only trigger on the printer model C792.
