Color/BW option not given in print dialogs when ColorModel is in cups_vendor_ppd_options

wsgcsysadmin commented 7 years ago

Printer: Canon ImageRunner iR-ADV C5235 CUPS: v.1.5.3 running in Debian Wheezy CPC: gcp-cups-connector version DEV (downloaded and built yesterday from docs in wiki) Go: version go1.8 linux/amd64

Print dialogs in Chrome(Windows, Linux, V56) and ChromeOS do not show a color/bw option. Previews show in black and white. Printing comes out in color. The CUPS web interface does show the Color Mode option for the printer defaults setup. The native drivers(Linux using same PPD, and Windows) do show the color/bw option and it is functional.

root@etl-2:/# lpoptions -l -p CO_Copier | grep -i ColorModel ColorModel/Color Mode: *Default Gray Auto

ZIP file attached with the PPD and gcp-cups-connector.config.json. ppd-and-config.zip

Please let me know if there is any other information you need. Thanks.

I should also add two more points here:

when the old Chrome-based connector was in use the color mode option was present.
when I set "cups_vendor_ppd_options" to "all" I get piles of options in the print dialog, but none for selecting the color mode.

When re/starting CUPS or saving printer defaults the following is logged.

I've been unable to determine is this is a concern or not.

The behavior is the same on my laptop: Ubuntu 16.04 x64 Go v1.6 CUPS v2.1.3

Is there any way of seeing what CPC is sending to Google about the printer?

When the CUPS printer's color setting is "Printer default" the job is sent as CUSTOM_MONOCHROME:

D [09/Mar/2017:09:33:43 -0600] [Job 051c775a-322e-c97d-8d32-b37da0d0448e] Assembled with file /tmp/cloud-print-connector-115776501: &{VendorID:ColorModel:Default Type:CUSTOM_MONOCHROME}

When the CUPS printer's color setting is "Black and White", the job is sent as STANDARD_MONOCHROME:

D [09/Mar/2017:10:27:11 -0600] [Job 30d7250e-4ac2-1987-722b-670813c487a2] Assembled with file /tmp/cloud-print-connector-499801095: &{VendorID:ColorModel:Gray Type:STANDARD_MONOCHROME}

And when the CUPS printer's color setting is "Color", the job is sent as CUSTOM_MONOCHROME:

D [09/Mar/2017:10:32:27 -0600] [Job ef655ceb-2d46-9bbd-f20a-2aece1566cbc] Assembled with file /tmp/cloud-print-connector-113397520: &{VendorID:ColorModel:Auto Type:CUSTOM_MONOCHROME}

The cloud print connector was restarted after each change to CUPS and before printing.

In all cases the print preview on Google is in black and white and the printer info on Google always shows: cpprint-color-mode-default color cpprint-color-mode-supported monochrome,color

And again, there is never an option in the Chrome print dialog for color mode.

Try changing your ColorModel section from this

*OpenUI *ColorModel/Color Mode: PickOne
*OrderDependency: 50.0 AnySetup *ColorModel
*DefaultColorModel: Default
*ColorModel Default/Printer Default: ""
*ColorModel Gray/Black and White: "<</ProcessColorModel /DeviceGray>>
systemdict /setpagedevice get exec"
*End
*ColorModel Auto/Color: "<</ProcessColorModel /DeviceCMYK>>
systemdict /setpagedevice get exec"
*End
*CloseUI: *ColorModel

to this:

*OpenUI *ColorModel/Color Mode: PickOne
*OrderDependency: 50.0 AnySetup *ColorModel
*DefaultColorModel: Gray
*ColorModel Gray/Black and White: "<</ProcessColorModel /DeviceGray>>
systemdict /setpagedevice get exec"
*End
*ColorModel CMYK/Color: "<</ProcessColorModel /DeviceCMYK>>
systemdict /setpagedevice get exec"
*End
*CloseUI: *ColorModel

Would it have any effect?

wsgcsysadmin commented 7 years ago

That did it. Color option is now present and works.

Color/BW option not given in print dialogs when ColorModel is in cups_vendor_ppd_options #347
