Double architecture (64-bits & 32-bits)

Hi all,

I've installed

sudo apt install cups
sudo apt install printer-driver-brlaser

for my HL-3150CDW Brother laser printer. I was able to install my it using cups web interface

http://localhost:631

which recognized correctly the right model.

Unluckily, when I try to print a simple text, the printer outputs tens of blank pages. I guess there might be a problem whit the brlaser driver.

I tried to install the specific driver from Brother's web site, but only a 32-bit version is available. So I'm not able to install it on my 64-bit Q4OS laptop.

I've read that it is possible to install multiple architectures (32-bits and 64-bits), but I fear to damage my Q4OS installation. I'm now using it regularly and I don't want to risk to corrupt it and to have to reinstall everything from scratch.

I don't want to get all installed libraries having their 32-bits flavor installed aside, nor to have future program installations install both versions.

Moreover I don't know if Q4OS 64-bits kernel will support the installation of the 32-bits architecture.

Any advice would be much appreciated.

Laurent

Re: Double architecture (64-bits & 32-bits)

I use the Brother installer for my HL-L2340DW and it usually installs the 32 bit packages it requires, this has always resulted in an apt error which can be easily fixed by adding the i386 architecture properly (sudo dpkg --add-architecture i386) and after refreshing apt (sudo apt update) the error should go away, after all this I have not had any problems printing

I have recently installed from this installation script (after yet another fresh install) without issue and haven't had the need to manually install/configure anything else, and this was all done over WiFi too.

Hi Dai_trying,
Thanks for your reply.
I've added the i386 architecture and updated apt, then installed Brother's i386 packages and my printer is now able to print correctly
