Hi,
I aksed some questions about this topic before and I got some usable answers
from Michael Sweet but I'm still missing a link.
The problem:
I have developed and built PDE based printer drivers for some time now. When
Tiger came out I installed the Panther (thus PowerPC based) on Tiger systems
and they worked without complains.
Building with Intel based Tiger I see that functions like:
- ppdOpenCompiledPPDFromTicket
- ppdGetMainIndex
- ppdCloseCompiledPPDFromTicket
are reported with the warning deprecated.
I've spent some with the documentation (and the answers I got from Michael
Sweet) and came to the following solution:
This code is present in my PDE's Initilize function:
CFMutableDictionaryRef ppdDict = NULL;
OSStatus result = noErr;
PMTicketRef PrintSettingsTicket;
OSStatus PMTicketCreateResult = PMTicketCreate (kCFAllocatorDefault,
kPMPrintSettingsTicket, &PrintSettingsTicket);
if (PMTicketCreateResult != noErr)
{
VERBOSE("OCPDEpaper: Initialize: PMTicketCreateResult = %d\n",
PMTicketCreateResult);
}
result = PMTicketGetPPDDict (PrintSettingsTicket, kPMTopLevel, kPMTopLevel,
&ppdDict);
// 1
if (result == noErr)
{
CFStringRef str = NULL;
if (CFDictionaryGetValueIfPresent (ppdDict, CFSTR("OCPDEpaper"), (const
void **)&str))
{
VERBOSE("OCPDEpaper: Initialize: OCPDEpaper found with
PMTicketGetPPDDict\n");
if (CFStringCompare (str, CFSTR("Upper"), 0) == kCFCompareEqualTo)
// 3
{
//*bin = UPPER;
}
else
{
//*bin = LOWER;
}
}
else
{
VERBOSE("OCPDEpaper: Initialize: OCPDEpaper NOT found with
PMTicketGetPPDDict\n");
}
}
else
{
VERBOSE("OCPDEpaper: Initialize: PMTicketGetPPDDict (printSettings,
kPMTopLevel, kPMTopLevel, &ppdDict) failed result =%d\n", result);
//*bin = UPPER;
// 4
}
//return result;
The main part of this code is copied from the document Extending Printing
Dialogs, Custom tasks, Handling PostScript Features.
In this document a function
OSStatus MyGetOutputBin (CFTicketTicketRef printSettings, MyBinType *bin)
is described. What I miss is how a correct
CFTicketTicketRef printSettings is created. The function calling
MyGetOutputBin is responsible for doing that.
In my code sample above I tried doing that with:
PMTicketRef PrintSettingsTicket;
OSStatus PMTicketCreateResult = PMTicketCreate (kCFAllocatorDefault,
kPMPrintSettingsTicket, &PrintSettingsTicket);
.
.
result = PMTicketGetPPDDict (PrintSettingsTicket, kPMTopLevel, kPMTopLevel,
&ppdDict);
I don't get any errors and still my entry "OCPDEpaper" is not found in the
PPD file though Im certain it is there.
What could be wrong?
Furthermore I wonder what happened to PDE strategy as a whole, in the old
could I had to lookup my PDE keyword up in the PPD file during initialize
and if not found I would return "kPMInvalidKey" to notify that the PDE
should not be attached or "noErr" to indicate that the PDE should be
attached. I don't see any of this back in the current documentation.
Who can help?
Regards,
Hans
PS: BTW I guess that this is the same problem as Yu Min is facing in his
question about "If have universal bunary libcups?"
