Hoi Eric 😊 This is my list of the DELL inspire 1525 with pcisleep

My guess is that this should not matter: There should be a generic category of USB printer ports supported by the cable. But we have actual USB experts here who may either confirm that intuition or say that I am totally wrong :-) https://www.usb.org/sites/default/files/usbprint11a021811.pdf > D) i dont have an ethernet (wired) connection yet with the laptop. Which chipset does the laptop use for wired networking? You can use PCISLEEP to check which devices you have. > E) DosUsb gives Errors when talking tot the printer. Sounds like a question for the USB expert(s) here! > My thoughts were to build a driver to talk to the ch341a in c or > assembly. To be continued You do not want to do that from scratch. For USB, there is a big mountain of stacked layers of logical structure and in operating systems with versatile USB support, you would only have a driver for the chip in context of all the already existing drivers for USB in general, which in turn support USB controllers on your mainboard in somewhat generic ways, to need less instance specific complexity. So what you would do in DOS is: Wonder whether the generic USB driver can treat the chip as instance of a generic USB printer port category and if not, whether you can get it supported by making it a special case of it with as small as possible differences, to not have to modify too much in the USB drivers. A driver "only for the chip" would not help you, as the chip always exists in some large, complex USB ecosystem.
