Hello all,
I am trying to setup an internal application that prints PDF documents
in an automated fashion to a set of known internal printers. I have
played with the various vendor settings in the Print dialog in Preview
long enough to get a saved set of print options that produce the color
output we want, and I'm now trying to apply these settings to my Cocoa
output. I have the printer writing the settings it receives on the
sides of the document, so I know that both my program and Preview are
setting the same driver options as desired; however, the color output
from my program is significantly different than Preview's, and I'm
hoping someone can shed some light on this discrepancy.
Here's the code I'm currently working testing with. (Yes, I know
getPrintOperationForPrintInfo:autoRotate: is a private method. This
isn't going to be a shipping application)
-(IBAction)test1:(id)sender
{
NSDictionary* printerPresets = [NSDictionary
dictionaryWithContentsOfFile:@"/Users/cbackas/Library/Preferences/
com.apple.print.custompresets.plist"];
NSMutableDictionary* ourPrinterSettings = [NSMutableDictionary
dictionaryWithDictionary:[[printerPresets objectForKey:@"Test
TrueColor Printing"] objectForKey:@"com.apple.print.preset.settings"]];
// Remove 'Apple' saved settings as they interfere with the Print
Settings we try to set below (Page Ranges etc)
NSEnumerator* keyCursor = [ourPrinterSettings keyEnumerator];
NSMutableArray* appleKeys = [NSMutableArray array];
NSString* oneKey = nil;
while (oneKey = [keyCursor nextObject])
{
if ([oneKey hasPrefix:@"com.apple"] && ![oneKey
contains:@"Color"]) // Preserve keys relating to Color operation
{
[appleKeys addObject:oneKey];
}
}
[ourPrinterSettings removeObjectsForKeys:appleKeys];
// Create the print settings.
NSPrintInfo *printInfo = [NSPrintInfo sharedPrintInfo];
[printInfo setTopMargin:0.0];
[printInfo setBottomMargin:0.0];
[printInfo setLeftMargin:0.0];
[printInfo setRightMargin:0.0];
[printInfo setHorizontalPagination:NSFitPagination];
[printInfo setVerticalPagination:NSFitPagination];
NSPrinter* thePrinter = [NSPrinter printerWithName:@"Odin"];
[printInfo setPrinter:thePrinter];
[[printInfo printSettings]
addEntriesFromDictionary:ourPrinterSettings];
PMPrintSettings printSystemSettings = [printInfo PMPrintSettings];
PMSetPageRange(printSystemSettings,1,kPMPrintAllPages);
PMSetFirstPage(printSystemSettings,1,true);
PMSetLastPage(printSystemSettings,kPMPrintAllPages,true);
PMPrintSettingsSetJobName(printSystemSettings,(CFStringRef)@"Test
Job");
PMSetCopies(printSystemSettings,1,true);
PMSetDuplex(printSystemSettings,kPMDuplexNoTumble);
PMSetCollate(printSystemSettings,true);
[printInfo updateFromPMPrintSettings];
// Create the document reference.
PDFDocument *pdfDocument = [[[PDFDocument alloc] initWithURL:[NSURL
URLWithString:@"file://localhost/Volumes/Users/cbackas/Test.pdf"]]
autorelease];
NSPrintOperation *op = [pdfDocument
getPrintOperationForPrintInfo:printInfo autoRotate:YES];
// Run the print operation without showing any dialogs.
[op setShowsPrintPanel:NO];
[op setShowsProgressPanel:NO];
[op runOperation];
}
