“All About Printing”

By Alan Wootton, President, Top-Notch Productions, MacTutor Contributing Editor

This month's topic is printing. As an example I present a program that will print a message in large, 'banner' format. Perfect for parties!

To those of us who are familiar with the older generation of computers, printing is a matter of sending data through ports and using printer control codes. For the Mac we take these details for granted and will concentrate on using pre-packaged drivers and on the details of GrafPorts.

Background

Printing on the Mac is done through the Printing Manager, RAM software that is considered part of the low-level operating system software. This code is stored in the system file and loaded into RAM. The Printing Manager interfaces between your program and the actual printer driver that controls the printer. The Imagewriter and LaserPrinter files are printer drivers called by the Printing Manager. The "Choose Printer" desk accessory switches between the two drivers so the Printing Manager has the correct driver installed and ready to go. To be more specific, the Imagewriter and LaserPrinter files are printer resource files, which contain device driver code within them to drive the respective printer. The "Choose Printer" DA copies the selected printer driver and it's data structures from the printer resource file into the system file, and that's the driver that the Print Manger then uses. The idea is that a Mac application can be written using printing manager calls and be printer independent, since the printing manager would then interface to the appropriate device driver, eliminating the need to re-code an application for a different printer. This ideal comes close to being achieved on the Mac, probably more than any other computer system, but is still far from perfect.

The intent of the Mac designers was that printing would be transparent to quickdraw graphics "printed" on the screen. This was accomplished by using a special quickdraw grafport for printing. Normal quickdraw routines are used to draw into this port. The Printing Manager converts these quickdraw calls in your grafport to printer calls to drive the printer instead of the screen. In this way, printing is supposed to be transparent to a normal screen drawing operation. It also explains the complexity of printing, since it involves all the quickdraw screen graphics technology.

Draft versus Standard Quality

The Printing Manager is responsible for the dialog boxes that appear prior to printing and for allowing draft or standard quality printing. These two modes are fundamentally different. In draft mode, the ascii representation of the quickdraw calls are sent to the printer, which prints the text of the document using the character generator within the printer. Hence no graphics are supported except character graphics or modes directly supported by the printer and driven by the user's program. The printer responds to it's own command codes rather than any of the "Mac" like graphics.

Spool File versus Printing the Spool File

Standard and high quality modes are completely different. In these modes, the printer is controlled bit by bit and the entire document is converted into a giant bit mapped graphics dump. A temporary quickdraw picture is first composed on disk called the spool file. This spool file is then read into memory, converted into an array of dots by bands, and sent to the printer. The bands are necessary because of the huge amount of memory required by bit-mapping an 81/2 by 11 inch page. For the imagewriter, this amounts to 256K of memory. For the LaserWriter, over a megabyte! The task of first creating a quickdraw picture for the spool file, and then imaging (converting to a bit-map) and printing the spool file band by band, are handled seperately by the printing manager. In fact, it is supposed to be possible to create several spool files for printing later, but no one seems to be using that ability. Inside Mac appears indecisive about printing, saying that printing spool files is done by the Printer utility, the code of which has apparently been integrated into the Finder. But Printer does exist as a seperate utility that will read a spool file, image it and print it. Since hardly any applications leave the spool file lying around, there hasen't been much opportunity to use the Printer utility.

Print Manager Calls: Lisa Pascal to Mac Pascal

In the printing chapter of Inside Mac a lengthy list of data types is presented along with 14 Pascal procedures and functions. This is the printing interface, but it is not made clear exactly where these procedures are found. The idea is that you are supposed to simply include the declarations and calls in your program and then link with a printing module. What is misleading about this is that the link is not with the procedures you think you are using but merely a piece of "glue". The actual code used to drive the printer is in the file 'Imagewriter' (usually in the system folder). Naturally, the code is in resources.

Imagewriter

To get a handle (pun intended) on printing, I examined the link module provided by Owen Densmore. I then duplicated Owen's algorithms in Pascal. You can find my versions of all 14 procedures in the following program.

The first task is to open a resource file. I said a bit on resources last month and there is never enough I can say about them. You should take a look in 'Imagewriter' and see what is there. The resources of interest here are of TYPE PDEF. These resources are actual printer-specific code. The code we need is in PDEF#0, PDEF#1, PDEF#4, and PDEF#5. In 'Imagewriter' is also a driver DRVR#-8192 named, '.print', but the one actually used is installed in the file, 'system'. The other stuff is for support of the dialog boxes the print manager presents. Rather than simply OpenResFile('Imagewriter');, we must take into account the possibility that there is more than one printer. To this end there is a resource STR #-8192 which contains the name of the print resource file. Therefore the print procedure PrOpen is ResID := OpenResFile( GetString(-8192) ); along with PBOpen of '.Print'. PrClose is simply CloseResFile(ResID). The other print procedures are in the PDEF resources and begin at various offsets into those resources.

The function GetAddress is used in the program to load one of the PDEF's (GetResource) and then to lock it in place (Hlock). It is then dereferenced and the offset is added. Once we have an absolute address to use we need a way to pass control to it. To do this I created the array jsr[0..3] of integer which contains code to JSR to the address on the top of the stack. Once again I take advantage of the fact that InlineP leaves register A0 pointing 2 bytes behind of the place we must return to. If you know no 68000 assembly you can ignore this.

The final detail to emulating the print interface code is that some of the routines release the PDEF handle and others leave it locked in place. This is the purpose of ReleaseAddress. Further, note that some of the routines use different PDEF's (0,1,2 or 3) depending on the setting of bjDocLoop. This is the purpose of MethodAdd. I find this a rather obscure feature and it will not be used here; nonetheless, the interface presented is complete, I think.

GrafPorts for Printing

It is necessary to use the type declarations to print but it is not necessary to closely study their form or function. I suggest studying my print record declarations in the program below along side "Printing Resources" in the new telephone version of Inside macintosh, where the print data structures are explained. A print record is created and filled in by the Printing Manager and the print dialog boxes. The printing port is set by a variant record type so that your program can write into the port as if it were a regular grafport, while the Printing Manager can modify the grafport for the printer.

The central issue is one of drawing in a GrafPort. Essentially, printing is no different than updating the contents of a window except that the size of the window is huge. To simply print a picture use a sequence like PrOpen, PrintDefault, PrOpenDoc, PrOpenPage, draw your picture, PrClosePage, PrCloseDoc, PrPicFile, and PrClose. To print more pages repeat PrOpenPage, draw, PrClosePage. Note the perfect symmetry with the exception of PrintDefault and PrPicFile. PrintDefault will fill in all those nasty hPrint fields for you and PrPicFile actually drives the printer. You may also modify your hPrint with PrStlDialog and PrJobDialog. These two present very familiar dialog boxes.

In the following program the procedure DrawPic draws a large picture in whatever port is current. In the main body of the program DrawPic is called several times to demonstrate the use of SetOrgin to show different views of the big picture. Of course, the parts of the picture that don't fit are chopped off by quickdraw and the same will happen when we print. I have found some strange complications. When printing, the VisRgn of the print port is not used, rather the clipRgn is used to delineate the usable area. In contrast, the drawing example opens up the ClipRgn and the VisRgn presents the limits. To investigate put:

with MyPort^.VisRgn^^.rgnBBox do writeln(top,left,bottom,right);  

in various places.

If you are doing a picture that is larger than one page don't assume the size of the page. You won't have to mess around in the grafport because you can use the rectangle hPrint^^.prInfoPt.Rpage to obtain the necessary offsets. Rpage.top and Rpage.left are zero so use right and bottom. I think this is the only one of the many hPrint fields that is commonly useful.

To make a banner, as promised, you will need the newer version of Imagewriter (sometimes called Imagewriter 15) or else there will be breaks between the pages. For banner format choose 'wide' and 'no breaks between pages' on the style dialog. You can change DrawPic to make any picture you please.

If there is any, and I mean any, subject that you think needs to be covered, write to me care of MacTutor and I will give it a try. I figure that if we can print with MacPascal then MacPascal can do just about anything.
