The fix provides ability to print Black & White pages on macOS.
Cocoa API has
[PMSetColorMode](https://developer.apple.com/documentation/applicationservices/core_printing/1805783-pmsetcolormode)
function but it is marked as deprecated and really does nothing.
There is no replacement; this function was included to facilitate porting
legacy applications to macOS,
but it serves no useful purpose.
Dumping `NSPrintInfo` print settings which were set by the native print dialog
on macOS shows that the keys and values used for Black & White printing depend
on the used printer type.
For example, the tested
`HP Color LaserJet MFP M180n` printer uses `ColorModel` key and`Gray` value, and
`HP Ink Tank 110 series` uses `HPColorMode` key and `grayscale` value.
Printing all `NSPrintInfo` presets shows that they do not contain key/value
pairs for Black&White settings.
This is the code snippet used to print `NSPrintInfo` presets:
PMPrinter pr;
PMPrintSession printSession = (PMPrintSession)[printInfo PMPrintSession];
OSStatus status = PMSessionGetCurrentPrinter(printSession, &pr);
CFArrayRef presetsList = nil;
status = PMPrinterCopyPresets(pr, &presetsList);
CFIndex arrayCount = CFArrayGetCount(presetsList);
for (CFIndex index = 0; index < arrayCount; index++) {
PMPreset preset = (PMPreset)CFArrayGetValueAtIndex(presetsList, index);
CFStringRef presetName = nil;
if (PMPresetCopyName(preset, &presetName) == noErr &&
CFStringGetLength(presetName) > 0) {
NSLog(@" presetName: '%@'", presetName);
NSDictionary* dict = nil;
if (PMPresetGetAttributes(preset, (CFDictionaryRef*)(&dict)) ==
noErr) {
// print preset dict
The idea of the proposed fix is to store printer dependent key/value pairs in
the `<jdk-home>/conf/printer.properties` property file.
The property file has the format:
print-attribute.print-attribute-value.key=value
where `print-attribute` is the java print attribute, `print-attribute-value` is
the corresponding attribute value, and `key` and `value` is the key/value pair
used by a specific printer.
For example, for `Chromaticity` attribute the property file could look like:
Chromaticity.MONOCHROME.ColorModel=Gray
Chromaticity.COLOR.ColorModel=CMYK
Chromaticity.MONOCHROME.HPColorMode=grayscale
Chromaticity.COLOR.HPColorMode=color
where `Chromaticity.MONOCHROME` key prefix corresponds to
`Chromaticity.MONOCHOROME` print attribute constant with (`ColorModel`,
`Gray`) and (`HPColorMode`, `grayscale`) key/value pairs.
Similarly `Chromaticity.COLOR` key prefix with (`ColorModel`, `CMYK`) and
(`HPColorMode`, `color`) key/value pairs correspond to `Chromaticity.COLOR`
print attribute.
https://www.openprinting.org/download/PPD/ site has been used to collect
`monochrome` and `color` constants from ppd files and save them in
`<jdk-home>/conf/printer.properties` file.
For example, for the Brother printer the
https://www.openprinting.org/download/PPD/Brother/BR9440_2_GPL.ppd ppd file
defines `BRPrintQuality` option:
*OpenUI *BRPrintQuality/Color/Mono: PickOne
*OrderDependency: 15 AnySetup *BRPrintQuality
*DefaultBRPrintQuality: Auto
*BRPrintQuality Auto/Auto: "
<</BRProcessColor 4 /BRHrc 0>>setpagedevice
<</BRColorAdapt true>>setpagedevice
<</BRRenderMode false>>setpagedevice"
*BRPrintQuality Color/Color: "
<</BRProcessColor 4 /BRHrc 0>>setpagedevice
<</BRColorAdapt false>>setpagedevice
<</BRRenderMode false>>setpagedevice"
*BRPrintQuality Black/Mono: "
<</BRProcessColor 1>>setpagedevice
<</BRColorAdapt false>>setpagedevice
<</BRRenderMode true>>setpagedevice"
...
*CloseUI: *BRPrintQuality
which is listed in the `printer.properties` file as:
Chromaticity.MONOCHROME.BRPrintQuality=Black
Chromaticity.COLOR.BRPrintQuality=Color
and for the Epson printer the
https://www.openprinting.org/download/PPD/Epson/epal2600.ppd ppd file defines
`EPRendering` option:
*OpenUI *EPRendering/Color Mode: PickOne
*% EPRendering must be after EPColorModel
*OrderDependency: 50 AnySetup *EPRendering
*DefaultEPRendering: None
*EPRendering None/Mono: "
<</ProcessColorModel (DeviceGray)
/DeviceRenderingInfo <</Type 29 /ValuesPerColorComponent 256>> >>
setpagedevice"
*End
*% ProcessColorModel is already set in EPColorModel
*EPRendering RGB/Color: "
<< /ProcessColorModel (DeviceRGB) >> setpagedevice
<</DeviceRenderingInfo <</Type 29 /ValuesPerColorComponent 256>> >>
setpagedevice"
...
*CloseUI: *EPRendering
which is listed in the `printer.properties` file as:
Chromaticity.MONOCHROME.EPRendering=None
Chromaticity.COLOR.EPRendering=RGB
The full list of constants from https://www.openprinting.org/download/PPD/ used
in `printer.properties` is
# Brother

Chromaticity.COLOR.BRPrintQuality=Color
# Dell

Chromaticity.COLOR.DLColorMode=Color
# Epson

There are printers with the same color attributes and different values.
For example, Kyocera defines `ColorModel` Color option as `CMYK` in
https://www.openprinting.org/download/PPD/Kyocera/en/Kyocera_CS-C4035E_en.ppd
file:
*OpenUI *ColorModel/Color Mode: PickOne
*OrderDependency: 10 AnySetup *ColorModel
*DefaultColorModel: CMYK
*ColorModel CMYK/Color (CMYK): "<< /ProcessColorModel /DeviceCMYK >>
setpagedevice"
*ColorModel Gray/Monochrome: "<< /ProcessColorModel /DeviceGray >>
setpagedevice"
...
*CloseUI: *ColorModel
and Samsung defines the same `ColorModel` Color option as `Color` in
https://www.openprinting.org/download/PPD/Samsung/PS/Samsung_C2670_Series.ppd
*OrderDependency: 70 AnySetup *ColorModel
*DefaultColorModel: Color
*ColorModel Gray/Grayscale: "<</ProcessColorModel /DeviceGray>> setpagedevice"
*ColorModel Color/Color: "<</ProcessColorModel /DeviceCMYK>>
setpagedevice"
*CloseUI: *ColorModel
The fix has been tested with 2 color printers `HP Color LaserJet MFP M180n` and
`HP Ink Tank 110 series`.
`HP Color LaserJet MFP M180n` uses `ColorModel` key and `Gray` value for black
& white printing.
`HP Ink Tank 110 series` uses `HPColorMode` key and `grayscale` value.
Only `HPColorAsGray` option with `Yes` and `No` values is listed in
https://www.openprinting.org/download/PPD/HP files.
For example,
https://www.openprinting.org/download/PPD/HP/HP_DesignJet_3500CP_PS3.ppd
*OpenUI *HPColorAsGray/Print Color as Gray: PickOne
*OrderDependency: 5.0 AnySetup *HPColorAsGray
*DefaultHPColorAsGray: No
*HPColorAsGray Yes/Yes: "<< /ProcessColorModel /DeviceGray >> setpagedevice"
*HPColorAsGray No/No: "<< /ProcessColorModel /DeviceCMYK >> setpagedevice"
...
*CloseUI: *HPColorAsGray
Both `HPColorAsGray` and `HPColorMode` options are added to the
`printer.properties` file as:
Chromaticity.MONOCHROME.HPColorAsGray=Yes
Chromaticity.COLOR.HPColorAsGray=No
Chromaticity.MONOCHROME.HPColorMode=grayscale
Chromaticity.COLOR.HPColorMode=color
