I suppose it's true that some of the info is in commercially available books so there might be issues making international purchases? The other resource that almost everyone using USB will have used are the books/documents by Jan Axelson: If anyone had any ideas please let me know.Does your country really block access to:Įveryone who has ever used USB has surely learned (or is that learnt?) most of what they know about USB from usb.org. From the moment it connected it reverse fed the paper and continued reversing even after the paper was out. The other cable wouldn’t allow the printer to be taken offline and it never allowed the printer to settle. This Qinheng CH340S allows me to switch the printer on and offline. I found an old parallel cable and proved the printer works with the Epson-9-Pin driver setup.įinally, I’ve networked the Dell laptop up to the Pi using an old router and I can print over the network, but it’s a lash up and I would prefer to use the cable if I can. I have an old Dell laptop with a parallel port. The other OSes give similar results to the Pi’s.Īs you can see, I don’t throw away working kit. I’ve tried the cable on a Win10 laptop, a Pi 3 & 4 with Bullseye and Buster, and a couple of laptops with Mint, Debian and Lubuntu. If I reboot the Pi while there’s a file in the print queue it prints several rows of signs. The Test Page goes to the print queue and it shows as processing but never completes. When I send a file to the printer the printer properties shows various messages. It creates an lp0 file in /dev/usb.Ĭups discovers it as usb://unknown/Printer but it doesn’t pass the print file to the printer properly. Judging by other peoples discussions, the adapter seems to have installed correctly. Has anyone managed to get one of these Qinheng CH340S USB to parallel adapters working with a Star LC-10 printer ?
