Even if you try to print from Linux to the printer OKI B841dn used at the University of Aizu With the Linux general-purpose driver, only a strange list of binaries appears. .. ..
There is no driver for CUPS of B841 on OKI's site. It is included in the driver for Mac, so extract it and use it! !!
wget https://www.oki.com/jp/printing/download/B841-PS-MX-DRV-200_43747.dmg 7z x B841-PS-MX-DRV-200_43747.dmg
Note that Filter is said to have "has insecure permissions" unless it has owner privileges (755).
I've worked hard so far, but in fact, "OKI B841dn" has a web print function. For example, at the University of Aizu, if you hit
<printer name> .u-aizu.ac.jp from your browser, you will see something like a management screen.
From there, select "Print" and a web print screen will appear, allowing you to easily print the pdf.
This is convenient if you want to print a little on a PC that does not have a driver. It's faster than printing with lpd because it's like caching everything in the printer before printing. (Oh, you don't have to have a driver ...)
