A Look At The PREC Resource

By Dave Kelly, MacTutor Editorial Board

As we all know the Apple ImageWriter printer has taken a back seat over the past several years to the LaserWriter. Most of us prefer Laser quality printing to that of the ImageWriter. However, another reality is the extra cost of the LaserWriter.

A quick look back in history reminds us that there are some previsions in the ImageWriter drivers which allow applications to “own” their own page sizes. This facility is brought to use by way of the PREC resource. In particular, the driver itself uses PREC resource ID=3 for the page size definitions as a default. If an application contains a PREC resource with ID=4 these size definitions take precedence. This may be old news to most of us, but it doesn’t seem to be well documented anywhere. The only place I found information about this was in some old notes from April, 1985. The Macintosh Technical notes don’t give any indication about this subject.

A sample RMaker source defining a PREC 4 resource that encodes the default configuration of the Page Setup Dialog is:

Type PREC = GNRL
*Paper size info -- localizable, customizable.
 ,4
 .I
*Number of paper-size buttons used (max is 6):
5
*6 paper sizes in 120ths (decimal!):
*1st number is vertical, 2nd is horizontal.
*First button: 8.5 X 11"  ‘US letter’ paper
1320
1020
*Second button: 8.25 X 11.66" ‘A4 letter’
1400
990
*Third button:  8.5 X 14"  ‘US legal’ paper
1680
1020
*4th button:8.25 X 12" ‘international fanfold’
1440
990
*Fifth button: 14 X 11"  ‘computer paper’
1320
1680
*Sixth button: - not visible
0
0
 .P
*Titles for six buttons.
US Letter
A4 Letter
US Legal
International Fanfold
Computer Paper
?

*The blank line just above this one is necessary!

One easy way of creating this type of resource is with RMaker. It may not be very convenient for non-programmers to create the resource without help. The Pascal application included here allows editing and creation of the PREC 4 resource. Handling the resource is not too difficult although there are a couple of things you need to know to manipulate the structure.

1. The type PREC is reserved for use by the Macintosh print driver. It should not be used in any other way than described here and not with any other resource ID other than 4. The PREC 3 resource in the printer driver itself could be modified although is not recommended.

2. Exactly six buttons must be defined in the PREC 4 resource even if you are not using all the buttons. One character titles should be used for unused buttons.

3. All PREC 4 numbers are in decimal.

4. The first item in the PREC resource is the number of buttons to be displayed, a word-size integer. Whatever number is used here will be used by the printer driver to determine the number of items in the Page Setup dialog. If you use a number greater than six you are in big trouble.

5. The dimensions follow next as an array of six pairs of integers. Each pair of numbers corresponds to the paper sizes with the first integer in each pair as the height and the second integer as the width. These numbers are given in 120ths of an inch.

6. The remainder of the data is presented as an array of variable length Pascal strings. To get to each string, these strings need to be handled as a byte or char array. The first byte is the length of the first string which is followed by the first string, followed by the length of the second string, and so forth.

I credit my assistant, Prototyper for the shell of this program with the necessary additions added for loading, saving and manipulating the PREC 4 resource. The List Manager is used to display and select the 6 possible buttons.

With all this said and done, it is good to note that Apple has announced that with System 7.0, spooling will be supported for all printers, not just the LaserWriter. Personally, I use the AppleTalk ImageWriter driver with 2 Macs wishing that the background printing was supported with the current system.
