Cancel printing on bad mode in PDDocWillPrintDocInMode

[#1]

Hi guys

I'm trying to force printing with document+comments with a plug-in as I want to replace the print command.

If I want to print silently, it's OK thru javascript

If I show the print dialog, the user may change the setting, my PDDocWillPrintDocInMode notification will reflect that.

If the mode is wrong, how do I cancel the whole print process?

Thanks

Christian

Pretty sure that you can't cancel printing from any callback. In theory you could provide a complete replacement for the print dialog, which guided the user in the choice of options, via replacing AVDocDoPrint. But that's a lot to replace.

[#4]

Hmm, you can also replace AVDocPrintPagesWithParams. This has potential, but take care and remember that the user may need to print files that are nothing to do with the system you are controlling.

Thanks, but AVDocPrintPagesWithParams do not give access to the choice of printing document and comments.

Only javascript seems to have that provision, but the user can alter the setting …

Is any action possible in a callback? (closing doc, cancel printing, …)

Yes you can – it’s the emitFlags value in the ParamRec

[#7]

Thanks Leonard,

I haven’t seen those flags….

Is it possible to set those flags and do not let the user modify them (or to force the value before print, disregarding th user choice for taht parameter?). Do we have access to that dialog and its ressources?

Thanks again for the lead

If you don’t bring up the dialog then the user can’t modify them - but if bring up the UI, they can change whatever they want.

[#9]

Is it possible to alter the UI so the popups are invalidated without reconstructing the whole dialog?

Can I use the native (Windows) functions to do so? and how?

[#10]

Nothing that Adobe supports. You are welcome to look for unsupported approaches.

[#11]

Under those circumstances, what is the usefulness of callbacks if we cannot react accordingly?

[#12]

Callbacks are useful for what they are designed for. You want to do something outside the design. Replacing UI behaviour isn't really a design strength, there are lots of potentially useful things you can't do.

I think replacing AVDocDoPrintWithParams may be your best bet. Don't know for sure that UI print calls this replaceable method but it's easy to test.
