Try a Quality Enhancement other than the default (0), which
accomplishes what I beliee to be the same thing.  Note that each step
doubles the printing time.

[Andrew X <68...@gm...>]

Is it possibly to add interleave method eight pass to p800? On 3880 this
method works wery good with clogged nozzles. I test all available methods
in p800 and no one can give a good result like eight pass on 3880

Glad you could find a workaround, this may help someone else in the
future too, hence the list reference added back in.

Hi,

What profile are you using?  You should use RGB, but should not
otherwise apply any profile -- treat it as generic sRGB.

[Gimp-print-devel] Color Input

[Brooke B. <lth...@at...>]

Downloaded Gutenprint 5.2.14 to facilitate using my HP 750 psc with my Mac mini using version 10.13.4 High Sierra.

I have had continuity issues when printing in color. I’m using a new color cartridge and it tests out in full color spectrum, yet I’m only getting pink for color, (as if the cartridge is depleted or the contacts are dirty - which they aren’t). 

Oddly, I have managed to get full color printing to work when I’ve deleted the printer, re-added it, reset the printer, and run disk utility etc.. Sometimes it works, sometimes it doesn’t. 

I’m selecting “color matching” and choosing an RGB profile before printing as suggested by your site. 

I’ve also removed the driver and re-installed it as a further possible “fix”. Restarting and then attempting to get the correct color printing, but to no avail.

Now I can’t get it to work at all, not even on occasion.

Unfortunately, I am not tech literate, but can usually assess things and find a way to make things work. However, I’ve hit a brick wall.

Your help would be much appreciated.

Thank you in advance,

Brooke

The printer appears to natively support Airprint and other network 
printing protocols, so there is a very good chance that CUPS will 
JustWork(tm) with it.

However, you may need a more up-to-date version of CUPS than what was 
bundled with Wheezy, which is now two releases out of date (and as of 
the end of 2018, completely unsupported).  Is there a reason you can't 
update to something newer?   (Jessie or better yet, Stretch).

[Gimp-print-devel] Raspberry compatible ?

[Merlijn V. <mer...@gm...>]

Hi gimp-print devs

Are these drivers compatible with a raspberry pi ?
because they have arm processors and I have experienced some issues with other software because of that.
If so, this mean I can use cups to just print with these drivers ?

Kind regards,

Re: [Gimp-print-devel] unable to uninstall Gutenprint

[Keeth A. <kee...@gm...>]

Thank you for your response Matt.  I appreciate it.

I was holding off on responding until I could tell you something firm.  

I installed Gutenprint 5.2.14 but was still unable to complete the Migration Assistant process.  It is unclear whether Gutenprint was still the culprit or not as the process kept timing out. However I did not get other error messages which specifically mentioned any other software except Gutenprint. 

I ended up migrating the data by hand — a tedious process but I needed to move things along.

At this point I believe I still have Gutenprint 5.2.14 installed.  I am running 10.14.3 on a 2018 MBP.  Happy to test some stuff for you if that helps. I’ll be offline through Fri or Sat this week.


Thank you,

Keeth

At least Apple's installers don't erase all third party software any more.  In any event, even now the Migration Assiostant wipes out thirdd party software receipts.  That is why the uninstaller does not work.  Every time you insetall software, it leaves a receipt in a hidden directory that lists all the files that were installed.  It is this receipt that the uninstaller uses to delete the old files.,  No receipt, no uninstall.

Fortunately, I can say that I have to retract my statement that there may be a problem with the new MacPower Book, macOS 10.14.x, and Gutenprint 5.2.14.  It appears that my printer is having all sorts of problems dealing with paper feed.  At least I think that is what it is. In any event, the new MacBook Pro is working using the Gutenprint 5.2.14 drivers.

Keeth, please download the Gutenprint 5.2.14 package and reinstall again.  That should replace any missing parts of the software.

Hi Elvira,
It looks like you are using the Canon driver, and not gutenprint.
So I afraid we cannot help you with your error.
Switch the driver to the gutenprint one and see how it works please.

You would need to set logging to debug, and then attach the relevant CUPS error log for the printjob in question, to see which filter is causing a problem. If that filter is one of the CUPS or Ghostscript filters before the job reaches gutenprint, that would be a different bug to file with the relevant organization.

Hello,

Downloaded 5.2.14 driver and installed on Mac Mojave.
Installed OK, printer set up using Gutenprint driver.
Using it opens the printer queue, but all it will do is say ‘printer ready’.
Clicking pause/resume results in the same again.
Do data sent to the printer by the lack of data light on printer.

Please help.

The HL-2030 is a so-called GDI driver, meaning it does not utilize a 
standardized printing protocol, relying instead on the manufacturer's 
drivers.

That said, Brother provides a Linux driver for the HL2030 for download 
from their web site.  Integrating it into the Synology firmware will 
require cooperation between Synology and Brother, and consequently is 
not something Gutenprint will be able to do.

When you set the CUPS log level to debug, just make sure you set the
file size to a large enough byte level (10MB or more maybe).
If you restart CUPS before doing your test maybe the log is rotated
(not sure) so you can start with a clean log.
Then hurriedly print the job and either stop CUPS or copy the log file
so it does not fill up more with the periodic CUPS messages.
You should easily find the messages regarding filters, and you can
always delete irrelevant CUPS messages in the copied log file
to make it more manageable.

Hope that helps.

Gernot

Extremely doubtful, a quick look online did not even bring up any
specs of what protocols this printer uses/supports.
If it has support for common formats, then there is always a chance to
use a driver for that particular format. On the other hand, if not,
then chances are effectively nil.

That is a CUPS question, and easily achieved I presume by setting CUPS
log level to debug.
It seems your issues are basically CUPS issues, so I would use the
CUPS mailing list to handle that.

Hi Tom,

I noticed the messages seemed to have become personal email ones,
maybe the list was not added when I replied from my phone.
Anyhow, I added the list back now, since the problem was not related
to the MG7700 driver, but to the fact that you do not have the driver.

> I loaded 5.2.14, but it requires at least Mac OS 10.6 to install. Unfortunately, Mac OS 10.6 requires an Intel processor whereas the iBook has a PowerPC processor. So where do I go from here?

I think that this will need input from others, from my perspective I
understand that there are too many problems with MacOSX that are
incompatible, and that periodically, in order to keep support
manageable, the minimum version required is upped depending on the
newest incompatibilities. Backports of printer support to older
versions of gutenprint compiled specifically for older versions of
MacOSX are not envisaged at the moment as far as I understand the
situation.
So sorry to have to tell you, you will probably need to set up another
computer as a print server and connect to that via the network (LAN or
WiFi).

[Gimp-print-devel] Driver for Brother Hl-2030

[Bastian R. <in...@ba...>]

Dear Team,

i wollte be very happy if you could add the Driver for Brother Hl-2030 so that the products of Synology would become fully compatible with this printer.
I actually can use the Driver from 2060 but it doesnt work properly. I dont get a print when i try to print from the DiskStaition from Synology.

Kind regards

[Gimp-print-devel] brother MFC-J6920DW

[Gene H. <ghe...@sh...>]

Greetings all;

Been here before folks.

Is there any chance that this printer can, or will be supported at some 
point with a non brother driver that actually works? Old cups 1.5.3 
here, on a wheezy install and something is filtering out all the fine 
tuning commands from the brother drivers intended to used with cups. So 
all the color adjusters that show up under the advanced menu selection 
when configuring this printer have zero effect, and the color printouts 
all are very pastel, as if every option was permanently set at -20.

Something I was recommended to try previously has even made the clean 
printhead into an unsupported command, requiring I do that from the 
printers own menu.

I have asked for, and been ignored, a description of the path in terms of 
what filters the data to print may be passing thru between the file to 
print, and whats fed down the cable to the printer in hopes I might be 
able to recompile it and make this printer usefull. The ppd supplied by 
the brother driver installer, has all these bells and whistles.

So I am asking again, what do I look at in hopes of finding this 
blockage. What is the chain of drivers/filters before it hits the cable, 
which can be either ethernet or usb, that makes no difference.  

Cheers, Gene Heskett

WIth the new printer the banding issue is gone, so it looks like

Hello Tom,
Can you confirm that the printer works fine via USB connection? I.e.,
that there is no issue with the actual gutenprint driver on your
system.
If there is a problem with USB, we would need a CUPs debug log.

If that is working fine, then the problems with networking would be
related to CUPS presumably, and a debug log would be necessary to
figure out more (and posting to the CUPS mailing list would help in
that case also).
