2On DP1.

3On T80 (by far the highest performance, for ALL scratch files). Expressed in 1024 word pages -- use at least 2000..

5At resolution of 384, this must be reduced to 10.6.

6These values vary somewhat from machine to machine, and from time to time. Use Align.Press to set precisely.

Appendix A -- Summary of Spruce Operation

See Appendix B for current version (1st digits of Spruce and Sprint versions must agree)

Starting Spruce

Type Spruce RestartCR to restart server without losing information. Failing that, or to start from scratch, type, e.g., Spruce ServerCR or Spruce Print xxxCR.

Server Mode Commands

Sstart/stop spoolingToggle "spooling switch".
Pstart/stop printingToggle "printing switch".
Ccheck queuePrint description of current printing queue.
Vverify queueSame as C, but requires keystroke after each line; P to finish.
Rreasonrequires one input line -- reason for Spruce unavailability.
Mmodify queueexhibits each queued file in turn. Respond with

Rreprint file
Aabort file
CRno modification -- go on to next
Pproceed -- print rest of queue entries and finish command.

QquitReturn to executive.

Stand Alone Mode Command Line Entries

Global Switches

/VverbosePrint more diagnostics
/DdebugUse standard debugging codes (currently 32, see below).

Command Line Options (e.g., Spruce/switches option <arg> option <arg> ...

ServerStarts Spruce in server mode. See above commands for interaction.
RestartRestarts without destroying print queue. Not guaranteed to work.
PrintArg is Press file name. File to print.
CopiesArg is number of copies. Default is 1.
PagesArg is <first> [ to <last> ]. Pages to print. Default is whole file.
ReprintReprints last document printed. Copies option applies.
XOffsetDefault 0.
YOffsetDefault 0.
ResolutionDefault 384.
PowerArg is on or off. Power off is not applicable to any current printers.
DebugArg is sum of debugging codes:

1Swat before file processing and printing.
2Inhibit file processing and printing, but bring in printing program.
4Swat on any error condition, unless also 512.
8Do not monitor Ether for print, status requests.
16Do not suspend processing and printing to accept more files.
32Run printing code, but do not print. Do not try to use printing hardware.
64Swat just prior to executing file processing code.
128Swat just prior to printing the file.
256Swat on return to spooler.
512Report all printing program errors to spooler -- do not enter Swat.

1024Spooler does not enter Swat on error, but tries to continue.

Trouble Shooting

Dover Ready light not on: Alto screen will (at intervals) contain further explanation (use P command to disable printing and freeze in display mode.) Clear printer condition, reenable Spruce printing if necessary.

Dover Ready light won’t come on, but there’s power to the machine: Push the "power on" button. If that doesnt’ work, call maintenance personnel.

Program is in Swat, or is obviously misbehaving: log the trouble, try to find software maintenance people. Failing that, boot and restart server.

After any problem: log the problem in the adjacent log book, or send a message to an appropriate authority.

Please do not leave a functioning Spruce printer without restarting the server.

Appendix B -- Spruce System History

The version numbers, dates of release, and dates of retirement (disappearance from on-line storage) are given for all relatively recent Spruce systems. For each release, a brief description of its purpose is included.
