The List data type is a list numbering tool that prints line-oriented text in a format that is easier to read. The List data type creates output that has:

• The file name at the top of each page
• The page number at the top of each page
• Line numbers for each line of the file
• Horizontal gray bars shading each page
• An end marker to indicate the end of the file

Figure 9-1 is an example of a page printed using the List data type.

Figure 9-1 List Data Type Output

9.1 Using the List Data Type

/PARAMETERS=DATA_TYPE=LIST

For example, to print the file XREPORT.TXT using the List data type, enter the following command:

$ PRINT XREPORT.TXT/PARAMETERS=DATA_TYPE=LIST

By default, DECprint Supervisor for OpenVMS prints using the List data type if the file extension is one of the following:

B32 CPP MMS BAS CXX PAS BLI FOR PLI C H R32 CBL HXX REQ COM MAR

See the DECprint Supervisor for OpenVMS System Manager's Guide for information about changing this list.

9.2 Using OpenVMS Forms with the List Data Type

The List data type ignores form settings for margins, page width, and so forth when formatting pages. It creates a page with maximum content at a size compatible with both A (Letter) and A4 paper:

Portrait orientation: 80 columns, 70 lines
Landscape orientation: 132 columns, 55 lines

However, any setup modules invoked by the form definition are applied to the print job.

This chapter describes how to print different types of files on a PostScript printer, and shows how to access the printer-specific features. Some features are not supported by all types of printers. You should be aware of the type of file you are printing, and the capabilities of your printer.

There are many types of PostScript printers with unique capabilities and features. Make sure your printer can perform the functions you specify in the print job. If your printer does not have a capability you request (for example, two-sided printing), your print job may be terminated and a message displayed to inform you of the problem. Some of the unique capabilities that may be available on your printer include:

• Two-sided (duplex) printing
• Variable paper sizes (envelopes, B-size paper, and so forth)
• Multiple input trays and input tray selection
• Multiple output trays and output tray selection
• Color printing

In addition to these printer-specific features, make sure the type of media you request is loaded in the printer before you enter the PRINT command.

10.1 Printing Two-Sided Documents

To select two-sided printing, use the SIDES parameter to the PRINT command.

The SIDES parameter provides the printing features listed in Table 10-1.

Table 10-1 Values for SIDES Parameter

Value	Definition
1, ONE, or ONE_SIDED_SIMPLEX	Your job prints on one side of the sheet.
2, TWO, or TWO_SIDED_DUPLEX	Your job prints on both sides of the sheet. The second side is reached by turning the page about its left edge, as in the binding of a book.
TUMBLE or TWO_SIDED_TUMBLE	Your job prints on both sides of the sheet, and alternating pages are rotated 180 degrees. Figure 10-2 shows the format for two-sided tumble printing. The second side is reached by turning the page about its top edge, as in some legal documents.
ONE_SIDED_DUPLEX	Your job prints on one side of the sheet but alternate pages may be offset for binding. Retains page layout for duplex printing for copying on duplex copiers. Reflects the placement of margins and page numbers.
ONE_SIDED_TUMBLE	Your job prints on one side of the sheet, and alternating pages are rotated 180 degrees. This allows you to make a tumble-formatted copy to take to a copying facility for multiple copies. Reflects the placement of margins and page numbers.
TWO_SIDED_SIMPLEX	Your job is printed on both sides of a sheet. This setting does not reflect the placement of margins.

10.2 Specifying Landscape and Tumble Printing

Figure 10-1 Landscape Orientation with Two-Sided Printing

To print pages in portrait orientation and tumble mode (as shown in Figure 10-2), use the SIDES=TUMBLE parameter. For example:

$ PRINT /PARAMETERS=SIDES=TUMBLE MYFILE.PS

Figure 10-2 Portrait Orientation with Two-Sided Tumble Printing

If you need a landscape oriented document printed on two sides and bound along the short edge (see Figure 10-3), use both the SIDES=TUMBLE and the PAGE_ORIENTATION=LANDSCAPE parameters in the PRINT command.

For example:

$ PRINT /PARAMETERS=(SIDES=TUMBLE,PAGE_ORIENTATION=LANDSCAPE) MYFILE.PS

Figure 10-3 Landscape Orientation with Two-Sided Tumble Printing

If you specify SIDES=TUMBLE for a print job destined for a printer that does not support tumble printing, your print job is terminated and the following message is displayed:

DCPS-E-TUMBNOSUP, printer-name does not support tumble printing

To display the SIDES parameter values that are supported by your printer, enter the HELP PRINT_PARAMETER SIDES command and select the subtopic that describes your printer.

10.3 Specifying Multiple PostScript Files in Duplex Print Jobs

Use the following command to print two PostScript files using both sides of the sheet:

$ PRINT /QUEUE=PS$A14 /PARAMETERS=SIDES=2 FILE1.PS,FILE2.PS

If FILE1.PS has three pages, page 1 is printed on the front of the first sheet; page 2 is printed on the back of the first sheet; and page 3 is printed on the front of the next sheet. Then, page 1 of FILE2.PS is printed on the back of that sheet, and so on.

To begin printing each new file on a new sheet, use the /FLAG, /BURST, or /TRAILER qualifier to print a file separation page between files. For example, the following command prints FILE1.PS and FILE2.PS and includes a flag page between each file:

$ PRINT /QUEUE=PS$DUPLEX /PARAMETERS=SIDES=2 /FLAG FILE1.PS,FILE2.PS

10.4 Specifying the Physical Sheet Size

You can specify the size of the physical sheet or type of media on which to print your file. The DECprint Supervisor software may assume this information automatically from the:

• Information inside the file
• Printer's default input tray
• Logical page size specified in the PRINT command (see Section 10.7).

You can explicitly request a certain sheet size by including the SHEET_SIZE parameter in your PRINT command to specify a value that describes the physical media size. For example:

$ PRINT /PARAMETERS=SHEET_SIZE=A4 MYFILE.PS

To list the values available with your printer, enter the HELP PRINT_PARAMETER SHEET_SIZE command and select the subtopic that describes your printer.

Some sheet sizes are known by multiple names, as listed in Table 10-2. You may use any of these names to specify a sheet size to DCPS. The DCPS term is the term that DCPS prints on the trailer page and reports in error messages.

Table 10-2 Sheet and Page Size Synonyms

DCPS Term	Synonym
Business_Envelope	Com10
7_Envelope	Monarch
Halfletter	Statement

10.5 Printing Multiple Pages on Each Side of the Sheet

You can print more than one page on each side of a sheet of paper. Printing this way saves paper and provides customized printed documents. Figure 10-4 shows four pages on each side of a sheet. Use the NUMBER_UP parameter in the PRINT command to specify the number of pages to print on each side of a sheet of paper. For example:

$ PRINT /PARAMETERS=NUMBER_UP=4 MYFILE.PS

To fit multiple pages on a side, the DECprint Supervisor software changes the size of the logical pages in the document to fit in the area on the physical side. This change does not affect the relationship of the page height to the page width.

10.5.1 Using NUMBER_UP with Input Tray Selection Operators

If you specify NUMBER_UP=1 for a file that has input tray selection operators, the printer changes paper trays, but the image is not resized to fit the new paper.

Input tray selection commands in a file are ignored if the file is printed with a NUMBER_UP value greater than 1. If you include the /NOTIFY qualifier in the PRINT command, a message is displayed to inform you of this action.

Figure 10-4 Printing Four Pages to a Sheet (NUMBER_UP =4)

When you print using NUMBER_UP, the aspect ratio (that is, the relationship of the height of the page to the width of the page) is preserved. Therefore, a portrait-shaped page retains its portrait shape. However, because NUMBER_UP may scale and rotate the pages to make the best use of the available space, the logical page and physical sheet may have different orientations.

Figure 10-5 Portrait Orientation with NUMBER_UP =2

The pages print vertically, but you hold the sheet in landscape orientation to read them. To print two pages per sheet using portrait orientation as shown in Figure 10-5, use the following command:

$ PRINT /PARAMETERS=(NUMBER_UP=2,PAGE_ORIENTATION=PORTRAIT) file-spec

To print two pages per sheet using landscape orientation as shown in Figure 10-6, use the following command:

$ PRINT /PARAMETERS=(NUMBER_UP=2,PAGE_ORIENTATON=LANDSCAPE) file-spec

Figure 10-6 Landscape Orientation with NUMBER_UP =2

10.5.3 Using NUMBER_UP with Multiple Files

For example, to print two ANSI files, one with seven pages and one with one page printed at four pages per sheet, enter the following command:

$ PRINT /QUEUE=PS40$A14 /PARAMETERS=NUMBER_UP=4 7PAGES.TXT,1PAGE.TXT

The first four pages of 7PAGES.TXT are printed on the first sheet. The last three pages of 7PAGES.TXT are printed on the second sheet; one page spot is left blank. The file 1PAGE.TXT is printed on the third sheet, with three page spots left blank.

To print two PostScript files, one with seven pages and one with one page, printed four pages per sheet, enter the following command:

$ PRINT /QUEUE=PS$IGUANA /PARAMETERS=NUMBER_UP=4 7PAGES.PS,1PAGE.PS

The first four pages of 7PAGES.PS print on the first sheet. The last three pages of 7PAGES.PS and the first page of 1PAGE.PS print on the second sheet.

To ensure that each new file in the multiple PostScript file job is started on a new sheet, specify file separation pages using the /BURST, /FLAG, or /TRAILER qualifier. For example:

$ PRINT /QUEUE=PS40$A14 /PARAMETERS=NUMBER_UP=4 /FLAG FILE1.PS,FILE2.PS

10.6 Printing a Range of Pages

You can print a specific page or range of pages in a print job.

To print a specific range of pages from the print job, include the PAGE_LIMIT parameter in the PRINT command and the range of pages. For example, to print only the 50th through the 100th page of a print job, enter the following command:

$ PRINT /PARAMETERS="PAGE_LIMIT=(50,100)" MYFILE.PS

The pages you specify do not correspond to the page numbers in the document. They represent the number of pages that have been printed. You can specify printing of just the last portion of this file by using the following command:

$ PRINT /PARAMETERS="PAGE_LIMIT=(50,)" MYFILE.PS

This example instructs the DECprint Supervisor software to start printing at the 50th page in the print job, and continue to the end of the print job.

You can specify printing of just the first part of a document by using the following command:

$ PRINT /PARAMETERS=PAGE_LIMIT=50 MYFILE.PS

This example instructs the DECprint Supervisor software to print the first 50 pages of the print job.

When you use the PAGE_LIMIT parameter, your print job completes when the upper-limit value is reached. Therefore, if you specify the PAGE_LIMIT parameter and do not print to the end of the file, you do not get a file trailer page for the file that was cut off. The rest of the data for that file and for any subsequent files for that print job is ignored.

10.6.1 Using PAGE_LIMIT with Multiple Copies

Do not use the PAGE_LIMIT parameter when you make multiple copies with the /COPIES or /JOB_COUNT qualifiers. The print job may be completed before the next copy begins printing. If you want to print multiple copies of a job for which you specify PAGE_LIMIT, use the SHEET_COUNT parameter (see Section 1.5).

10.6.2 Restarting Interrupted Print Jobs

You can save paper when you restart interrupted print jobs by using the PAGE_LIMIT parameter to start the print job near the point where the print job stopped. For example:

$ SET ENTRY /PARAMETERS="PAGE_LIMIT=(30,)" /RELEASE 301

In this example, print job 301 was released and printing started on the 30th page of the print job.

When you use the PAGE_LIMIT parameter with duplex (two-sided) print jobs, the software ignores the respective positions of left (verso) and right (recto) pages. The first page you specify with the PAGE_LIMIT parameter will always be a recto page.

The maximum PAGE_LIMIT value, for either the starting or ending page, is 999999.

10.7 Specifying the Logical Page Size

Certain types of files contain instructions for the size of the page that will be printed. The application that generates PostScript files, for example, assumes a certain media size and generates PostScript data to create pages of that size.

Note, however, that the logical page size specified in the file differs from the physical size of a sheet of paper. You specify the physical sheet size using the SHEET_SIZE parameter. Use the PAGE_SIZE parameter to specify the logical page size for files that do not have instructions for the page size.

If you do not specify SHEET_SIZE in your PRINT command, the PAGE_SIZE value is assumed to be the physical sheet size as well. In a print job where neither PAGE_SIZE nor SHEET_SIZE are specified, the DECprint Supervisor software assumes the size of the media loaded into the default input tray.

To list the PAGE_SIZE values supported by the DECprint Supervisor, enter the HELP PRINT_PARAMETER PAGE_SIZE command.

To print an ANSI file using a logical page that will fit on a business envelope, enter the following command:

$ PRINT /PARAMETERS=PAGE_SIZE=BUSINESS_ENVELOPE ADDR.TXT

If you include the PAGE_SIZE parameter in a print job for PostScript files, the parameter is ignored. However, you can include both the PAGE_SIZE and SHEET_SIZE parameters to allow the logical page to be adjusted to fit on the physical sheet (see Section 10.8).

Some page sizes are known by multiple names, as listed in Table 10-2. You may use any of these names to specify a page size to DCPS. The DCPS term is the term printed by DCPS on the trailer page and reported in error messages.

10.8 Changing the Size of the Printed Page

In a PostScript file, the page size is the size of the media that the application assumes when generating the PostScript file. In most cases, the page size and the sheet size are identical. However, you can specify a different page size and sheet size so that the logical page is scaled to fit on the physiscal sheet. For example, use the following command tp print B-size images on A-size paper:

$ PRINT /PARAMETERS=(SHEET_SIZE=A,PAGE_SIZE=B) MOD_LINE.TXT

When you specify the PAGE_SIZE and SHEET_SIZE parameters with different values, the DECprint Supervisor software automatically scales the pages to fit the sheet size, including borders around pages as if you had specified the NUMBER_UP parameter. You can use the LAYUP_DEFINITION parameter as described in Chapter 11 to disable borders.

10.8.1 Automatic Scaling When Queue Has PAGE_SIZE and SHEET_SIZE Parameters

DCPS assumes an implicit NUMBER_UP=1 when all of the following conditions exist:

• Queue default parameters for both PAGE_SIZE and SHEET_SIZE have been set to different sizes
• Your PRINT command does not specify these parameters:
  • PAGE_SIZE
  • SHEET_SIZE
  • INPUT_TRAY
• NUMBER_UP and LAYUP_DEFINITION are not specified for the queue or in your print command

NUMBER_UP=1 scales the logical page size to fit on the physical sheet size. This results in the same behavior as specifying different values for PAGE_SIZE and SHEET_SIZE on the command line without specifying NUMBER_UP or LAYUP_DEFINITION.
