Trivial annoyance

I have a brother DCP-L3510CDW colour laser printer. From Gimp I always print via gutenprint.

It works very well but when I select it I get a dropdown with over thirty rows saying unable to locate the ppd, except that it does.

There are two ppd files in /etc/cups/ppd:

Brother_DCP_L3510CDW_series.ppd 9.1kB DCPL3510CDW.ppd 26.3kB

Gutenprint always selects the second printer/ppd

In Cups under printers, the first "Make and Model" reads: Brother DCP-L3510CDW series, driverless, cups-filters 1.28.15 The second just reads: Brother DCP-L3510CDW CUPS

I am tempted to delete the first one

I can't answer your question but as I'm in the market for a colour laser printer can I pick your brains?

Would you buy this printer again? Apart from this issue, does it just work with Linux out of the box? What's the toner life like compared to the claimed life?

Thanks.

I have an HL-L8260CDW and CUPS is a bit weird because of the mDNS auto-detection - it will randomly fail to find the printer, change driver or print a page saying something like 'unknown format' (I think it's trying to send URF which the printer only supports over AirPrint, not over IPP). I do have a fairly complicated network setup which might be a reason, though.

I went into CUPS settings and changed the connection to AppSocket using its fixed IP and the driver to 'Brother MFC-8370DN BR-Script3' and it's much better - not randomly change settings.

Speaking for the HL-L8260CDW, definitely. HP, Lexmark, Epson and friends have got big into toner chipping and causing trouble if you don't use genuine cartridges. For mine a full set of colour cartridges (no chips, just a simple mechanical wheel to indicate fullness) is about £30-35. I've printed 18882 pages and probably spent only slightly more than £100 on toner. In fact I think paper is the bigger running cost.

Yes, it'll print fine just with the auto-detection.

No idea, I just buy a box of 4 cartridges for the £30 and replace them as and when needed. I think I've gone through 3 full sets of carts, although I complained to one seller about the magenta being leaky, got a refund and then rebought just a separate magenta cart. This site is my go-to for info on the reset wheel mechanism on the official cartridges:

there is also a hidden reset menu which works for me:

I do this when the printer moans about empty toner, and run the cartridges until there is actually no toner left (often a few weeks past the 'replace toner' message)

It's saying I'm on 38% drum life, which I think is rated at 30k pages. I think the secret reset menu can do that too, but if not a drum kit is about £100.

I think newer Brothers now have toner chips, but you can still use unofficial toner.

I have one of those printers, but have no idea what 'cups' is. I just print from my phone with the Brother/Android driver.

Should be no issues doing that, but if it autodetects like a bad smell a quick fix would be to disable Avahi.

# systemctl disable --now avahi-daemon.service

Or jumping into this rabbit hole ...

I would definitely buy this printer again. It's a bit slow but my requirements do not need high speed.

I was a bit careless when checking its spec and dismayed when I discovered it was Wi-Fi only. However in practise it has proved very reliable.

Cartridges are very small. I only buy compatibles and from reliable suppliers. The results are pretty good.

CUPS = Common Unix Printing System, the printing subsystem used by Linux and MacOS. Roughly equivalent to the Windows printer driver system.

Android and iOS use a much simpler way to talk to printers: no drivers to install, printers auto-detect via mDNS and all speak some common languages (URF for AirPrint, PWG over Mopria for Android)

I deleted the unwanted ppd

Ran the above command

and ensured the Brother DCP-L3510CDW series was deleted in CUPS.

I haven't tried the above yet.

I still get great prints but tons of "cannot find the ppd" messages which perhaps contribute to the slowness until it finds it. Bizarre.

CUPS and mDNS (Avahi) are both inventions from Apple, that I end up fighting with in Linux to control.

When one OS manufacturer cross-pollutes another OS with their tools...

I am not sure CUPS was. It got heavily taken up by apple, yes. wiki --

"Michael Sweet, who owned Easy Software Products, started developing CUPS in 1997 and the first public betas appeared in 1999. The original design of CUPS used the Line Printer Daemon protocol (LPD), but due to limitations in LPD and vendor incompatibilities, the Internet Printing Protocol (IPP) was chosen instead. CUPS was initially called "The Common UNIX Printing System". This name was shortened to just "CUPS" beginning with CUPS 1.4 due to legal concerns with the UNIX trademark. CUPS was quickly adopted as the default printing system for most Linux distributions. In March 2002, Apple Inc. adopted CUPS as the printing system for Mac OS X 10.2. In February 2007, Apple Inc. hired chief developer Michael Sweet and purchased the CUPS source code. On December

20, 2019, Michael Sweet announced on his blog that he had left Apple. In 2020, the OpenPrinting organization forked the project, with Michael Sweet continuing work on it. "

Avahi is an implementation of Apple's 'Zeroconf'.

In practice I found that going into my HP printers (web based ) configuration, setting it to a fixed IP address and turning off *almost everything* except IPP/IPPS and 9100 allowed me to set up CUPS simply and reliably.

I kept switching OFF stuff until it DID work simply, and reliably.

e.g.:-

IPv4: Enabled IPv6: Enabled DHCP: Disabled BOOTP: Enabled AUTOIP: Disabled TFTP Configuration File: Disabled Telnet configuration: Disabled DHCPv6: Enabled LPD Printing: Disabled LPD Banner Page Printing: Disabled FTP Printing: Disabled

9100 Printing: Enabled Bonjour: Disabled IPP Printing: Enabled IPPS Printing: Enabled AirPrint: Disabled SLP: Enabled WS-Discovery: Disabled WS-Print: Disabled SNMP: Enabled Show IP Address: Enabled LLMNR: Disabled Syslog: Enabled Enable DHCPv4 FQDN compliance with RFC 4702: Disabled ARP-Ping: Disabled eCCL: Enabled eFCL: Enabled

I have recollections of Apple sort-of hijacking it from the Linux community, several years ago ...

In that they are no worse than IBM with Linux.

I think CUPS is a huge improvement over LPR/LPD. And my recollection is that it got *better* after Apple got involved.

Not *everything* that Apple does is overpriced proprietary shit.

Just *most* of it :-)

Has Apple abandoned CUPS, the Linux's world's widely used open-source printing system? Seems so

The official public repository for CUPS, an Apple open-source project widely used for printing on Linux, is all-but dormant since the lead developer left Apple at the end of 2019.

Apple adopted CUPS for Mac OS X in 2002, and hired its author Michael Sweet in 2007, with Cupertino also acquiring the CUPS source code. Sweet continued to work on printing technology at Apple, including CUPS, until December 2019 when he left to start a new company.

Asked at the time about the future of CUPS, he said: “CUPS is still owned and maintained by Apple. There are two other engineers still in the printing team that are responsible for CUPS development, and it will continue to have new bug fix releases (at least) for the foreseeable future.”

Despite this statement, Linux watcher Michael Larabel noted earlier this week that “the open-source CUPS code-base is now at a stand-still. There was just one commit to the CUPS Git repository for all of 2020.” This contrasts with 355 commits in 2019, when Sweet still worked at Apple, and 348 the previous year. </cite>
