印度采购需求：永久记号笔、永久墨水、编码打印机、快干墨盒、钢笔墨水、永久性记号笔墨水

I'm looking for a reliable ink tank printer that can handle A4-sized paper. It's essential that the printer offers high-quality printing and cost efficiency, particularly with the ink usage. I'm interested in understanding the features that can enhance productivity, such as printing speed, connectivity options, and any built-in functionalities like scanning or copying. Additionally, I'd appreciate details on the ink tank system itself – how easy it is to refill or replace, and whether it comes with enough ink for an initial user experience. Also, please share your pricing, lead times for delivery, and any warranty options available. Looking forward to your prompt response so we can explore potential collaboration!
