| Subject | Question re postscript and pdf |
| Message-ID | <dl7bnmxdr4.ln2@Telcontar.valinor> |
Hi, As I see you talking about postscript, I want to pop a question that might be a bit offtopic, as it is about modern computing. context: Linux Printers talked postscript. Now I hear they talk PDF. I know that it is trivial to convert from ps to pdf. Do programs that want to print generate the PDF directly, or do they generate the ps and then convert it to pdf? It also occurs to me to ask what is the advantage for printers of talking pdf instead of ps. Thanks :-) -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;

Neither. Programs shouldn't care what format the printer can handle.
That's up to the cups printer driver, to take in what the program
generates and convert it to what the printer can deal with.
But I suspect any printer that can handle PDF can also handle postscript
(and plain text and probably PCL) so it's not "PDF or PS" but "PDF and
PS".
Heh, the HP LJ MFP-4301fdw claims "HP PCL 6, HP PCL 5e, HP PCL 5c, HP
Postscript level 3 emulation, PDF, URF, PWG Raster, Native Office"

I suspect more for printing from mobile devices; PDFs are common (eg
bank statements) so someone who is "phone first" may download a PDF
document on their phone, view it, print wirelessly. But even with
firefox on Linux, printing may generate a PDF (I just disabled the
queue, did a test print, saw it was a PDF in the queue).

The truth is the truth, and opinion just opinion. But what is what?
My employer paid to ignore my opinions; you get to do it for free.

AFAIK programs submit ps or pdf to cups.
Years ago, LO sent ps; so sait the pinter properties dialog. Now it
sends PDF, and when I notice I click so that it sends ps instead,
because my current printer does not talk pdf and it would be one extra
useless conversion.

PDF is, or at least was, a wrapper format around a subset of postscript. To get equivalent postscript, you just need to unwrap the postscript, and give it the extra stuff the pdf contains (like images or fonts) in a way it understands. To convert arbitrary postscript into a PDF, you need to rewrite the postscript to only use the non Turing-complete subset allowed in pdf, which I could see running into the halting problem and other fun stuff. However, once you do have the final result of the postscript execution, the pdf wrapping is indeed quite simple, with the most complicated bit being the cross-reference index that is "just" counting how many bytes away each object is from the beginning of the file. > It also occurs to me to ask what is the advantage for printers of > talking pdf instead of ps. The big one I know is that PDF is not Turing complete, while PS is. You don't want your printer running infinite loops or memory bombs or similar. A malicious postscript document doesn't need a buggy postscript interpreter to do it's dirty work, a malicious pdf needs to cause the interpreter to misbehave to do any damage. > Thanks :-) >

Adobe had a product called “Distiller” which did this. You ran a custom wrapper program on a PostScript interpreter, which I think intercepted all the actual rendering calls and output corresponding PDF objects instead. > The big one I know is that PDF is not Turing complete, while PS is. > You don't want your printer running infinite loops or memory bombs > or similar.

Basically, no variables, and no loops or other control constructs. So there is a one-to-one correspondence between objects in the page definition and objects on the page rendition.

I think the root of the problem was > that /etc/hosts file was empty. The one time I did this was when I had files modified for on-screen reading by inverting the colors. A hack that only worked for some files, in PostScript. Or maybe it was gv with default colors for screen reading (so light on black)? I forget which, it probably was the former. So, one day I printed a document and had to cancel it, as it was printing the *inverted* version... -- Nuno Silva

Am I wrong? What good free alternatives? What I see them doing is web pages with forms to fill, and data saved in their cloud. That works on any computer that runs a modern supported web browser. I had to hire a firm to do those PDF filling for me. They were already complicated to do, anyway. -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;

I did not look at recent specs, but PDF spec was freely available
and IIUC put no restricions on use. I was able to implement
my little PDF processing utility working from the spec. And
there were several free implementations of viewers and
associated tools. I certainly can do "full" PDF flow, that
is create them, view, convert to bitmaps, add some annotations
using only free tools. That is quite different from MS Word.
The PDF forms extention may be an exception.

The Office Open XML standard(s) were a response to the push that tried to promote ODF and other open formats on grounds that they were standards (or at least that seemed to be invoked too). Of course Microsoft was found to have a spec that didn't exactly match the implementation, and also proceeded to have the standard approved with shady practices (like people being refused to attend standardization meetings because of "lack of chairs"). In the end, it's probably a useless standard, existing only for the purpose of saying Office Open XML is standardized. (And given they gave a guy called Mike Rowe hell for naming his site and/or company "Mike Rowe Soft", they should probably have been barred from calling it "Office Open"...) What really matters is a decent spec, that matches the implementation, and that is freely accessible and usable, and having at least one compliant implementation that is FLOSS is probably not a bad idea as a requirement. Base PDF is probably different in that, it not being from Microsoft, may actually have an accurate spec and may be not a futile (to everyone else) exercise in pretending there is openness. > The PDF forms extention may be an exception.

Just say no. I only use OO. Of course I don't have a corporate IT department bribed by Microsoft trying to declare their stuff as a standard. People (mostly in Europe ATM) are starting to catch on.

I'm not sure - there seems to be a state of affairs now that's much worse than it was a decade or more ago. Back then, being a Microsoft shop/workplace/organization/... meant you had Active Directory, Exchange for mail and Windows machines galore. Nowadays it seems to mean the organization signed a contract passing a bunch of essential services to Microsoft's own premises in cloud-based offerings. So now the arguments to defend some silly arrangements might be that whatever is found needs to duplicate that - even if the cloud-based services are not that useful or are even counter-productive. Funnily, this may also make LibreOffice gain a footing: besides "no AI features", they can now perhaps more easily stand out with "you can install this and use it with no need for a network connection!". Who would think such a mundane thing from the late 90s could look like a premium feature in the 2020s... Also, you can use whatever colors you want and you don't risk your document losing colors or becoming black because Adobe had or has some deal with some company that somehow managed to trick the USPTO into letting them patent color names? (... hey, how come Pantone is not owned by Oracle?) -- Nuno Silva
