SOLVED: can't print after Oneiric->LMDE

[TomRoche]

summary: Brother HL2270-DW laser printed from Oneiric. After fresh install of LMDE-201403-UP8, CUPS sees the printer but can't print to it.

details:

I wanted to port a friend's desktop from Oneiric to LMDE. After a difficult start I've got most functionality restored, and in some cases improved. (LMDE *definitely* supports cinnamon better than Oneiric did.) One main problem remains: the printer.

This Brother HL2270-DW laser printed normally from the same desktop (except on Oneiric, a few days ago), so I'm pretty sure the printer is OK. The printer has a wired ethernet connection to a router to which the desktop connects wirelessly:

1. that topology is unchanged from before
2. the desktop can network via that SSID, so the desktop<->router connection seems OK
3. CUPS on the desktop sees the networked printer, so the printer<->router connection seems OK

I was able to install the printer drivers easily using Brother's new bash script=`Linux-brprinter-installer` (see the driver page), except that the script, on trying to print a test page (at end of its run) failed to find `lpr`.

I installed `lpr`, then started CUPS and did menu>Printers>HL2270DW. CUPS showed connection='usb:/dev/usb.lp0' so (still in CUPS) I did Administration>Modify Printer and changed connection to "Discovered Network Printers=Brother HL-2270DW series". I then (still in CUPS) did HL2270DW>Maintenance>Print Test Page and got error=connecting-to-device :-(

I tried restarting the printer (no change) and restarting the desktop (ditto). What to do?

Thanks to help from Brother Bob, I was able to get my GF's Brother HL-2270DW not only printing but duplexing, despite my previous broken install. See successful install procedure at this post to the OpenPrinting forum.

Hi Tom,
Your presentation is a masterpiece. GREAT JOB. I hope it helps others to Brother print with all the intended features of the printer.
