Changing the Number of Concurrent Print Jobs Allowed: -n
By default, NetWare for Macintosh v3.12 allows ten Macintosh print jobs (ten Printer Access Protocol connections) to write to a single AppleTalk print spooler at any given moment. If more than ten print jobs attempt to write to a print spooler concurrently, ATPS returns a message to the Macintosh indicating that the printer is busy. This message will disappear and the spooler will accept the print job as soon as one of the print jobs has been written to the queue.
If you wish to allow more or less than ten print jobs to write to a queue concurrently, use the -n option when configuring ATPS. For example, the following line creates a spooler named "NW LaserWriter2" and a queue named "NW_LASERWRITER2," and allows 5 Macintosh print jobs to be submitted concurrently:
"LaserWriter2:Engineering" -n5
Because the print spooler accepts jobs very quickly, a setting of less than ten should suffice for most sites. You can reduce the maximum amount of memory that could be used by the print queue and control the number of AppleTalk connections it can consume by limiting the number of print jobs it will accept at the same time.
The number of concurrent print jobs must be 50 or less. The amount of memory on the file server, available disk space, available AppleTalk stack connections, and processor time are factors to consider when increasing or decreasing the number of concurrent print jobs.
Assigning a Descriptive Name: -o
When you specify a configuration line in ATPS.CFG, you can allow ATPS to create a default print spooler name of "NW printer-name," or you can use the -o option to specify a spooler name explicitly. In either case, the queue name is derived from the spooler name.
The following configuration line specifies a queue for a LaserWriter named "Robin" in the "Publications" zone:
Robin:Publications -o "Doc Queue"
The AppleTalk print spooler will be named "Doc Queue" and the NetWare print queue used will be named "DOC_QUEUE."
AppleTalk print spooler names follow the rules for all Macintosh Chooser names: they can include up to 31 characters but cannot include the : or @ characters. NetWare print queue names can include up to 47 characters, and cannot include (in addition to : or @) spaces or the / \ ; , * ? % or + characters.
The name of a queue used by ATPS is derived from the spooler name by converting special characters and spaces in the spooler name to underscore characters, and converting uppercase and lowercase characters to all uppercase. The queue is created by ATPS if it does not already exist.
NOTE: You must use the -o option to name queues for serial, parallel, or remote printers. Because these printers are not on the AppleTalk network, ATPS cannot use the AppleTalk printer name in the default configuration syntax.
See Turning Off the AppleTalk Print Server: -wb for information about naming queues for serial, parallel, or remote printers.
Advertising a Queue in a Specified Zone: -o
In NetWare for Macintosh, the internal AppleTalk network is an extended Phase 2 network, which can support multiple zones. A reason for configuring multiple zones on an internal network is to advertise AppleTalk print spoolers in a zone other than the default internal zone. See Internal Network and Zone Configuration for more information about the internal network.
NOTE: Configuring an AppleTalk print spooler to appear in one of the multiple zones on the internal network is not recommended on AppleTalk internets that support Phase 1 routers. The spooler will not appear reliably to all Macintosh users.
To specify the zone in which the AppleTalk print spooler will appear in the Macintosh Chooser, use the -o option with this syntax:
-o spooler-name[:izone-name]
NOTE: When you specify a zone name following the spooler name, it must be preceded by a colon character (:). The zone name you specify must be one of the zones of the server's internal AppleTalk network. If a space character appears anywhere in the "spooler-name:izone-name" string, you must enclose the entire string in double-quotes.
spooler-name is the name of the AppleTalk print spooler, and izone-name is the name of the internal zone in which the print spooler will be visible. If you don't specify the izone-name parameter, the spooler will always appear in the default zone of the server's internal network (the first zone in the zones list specified for the internal network).
For example, assuming that the internal network has been configured with two zones, "Sales" and "Marketing," the following configuration line creates a spooler named "LW_queue," which will appear in the "Marketing" zone:
"my-printer:my zone" -o LW_queue:Marketing
If you wish to use the default spooler name ("NW printer-name") but you wish to advertise in a zone other than the default zone of the internal network, you can simply specify the izone-name parameter as follows:
printer-name:zone-name -o :izone-name
For example, the following configuration line creates a spooler named "NW my-printer" which will appear in the "Marketing" zone of the internal network:
"my-printer:my zone" -o :Marketing
The queue name will be visible to users of DOS users of the Print Queue module as "NW_MY_PRINTER."
Specifying a Printer Type: -t
To create a spooler or specify a printer other than the default LaserWriter type, you must specify the printer type on the configuration line by using the -t option. The -t option requires that you specify a valid NBP type. The default printer types are "LaserWriter" (the default), "ImageWriter," or "LQ."
The following configuration line sends print jobs to an ImageWriter LQ named "Reports IW" in the "Marketing" zone.
"Reports IW:Marketing" -t LQ
The AppleTalk print spooler will named "NW Reports IW," and the NetWare queue will be named "NW_REPORTS_IW."
If you wish to specify a printer type other than the default printer types, see AppleTalk Printers That Use a Different NBP Type.
Fully Compatible Non-Apple Printers
For printers that are truly compatible with the Apple LaserWriter, ImageWriter, or ImageWriter LQ, you can use the same configuration lines as those shown for the respective Apple printers in this chapter.
If the printer is a LaserWriter-compatible PostScript printer, there can be PostScript and TrueType font issues that might cause problems between the Macintosh LaserWriter driver and the printer itself. If you run into problems with PostScript extensions or TrueType fonts, contact the printer manufacturer.
