=== GT.M pipe for print DEVICE (older way): ===

With the introduction of the pipe device to GT.M (version V5.3-003) this simple, secure, and elegant method can be used:

* To begin, [[Begin_Configuration_of_Vista#Update_the_Devices,_Start_Taskman_and_Mail_a_Message|Update the Devices]] file. To create a new DEVICE, enter an unused NAME of your choice.

NAME: HP-PHOTOSMART
$I: <pipe>
PRE-OPEN EXECUTE: X "o ""p"":(command=""lpr"")::""pipe"" s IO=""p"""
POST-CLOSE EXECUTE: X "c ""p"""
SUBTYPE: P-OTHER80
TYPE: OTHER

Note: We use [[FILE_3.5|TYPE:OTHER]] rather than Host File Server. No host file needed; output will be "piped" to the default CUPS printer. Also the fancy stuff is in the PRE-OPEN EXECUTE. For example, one can write:

PRE-OPEN EXECUTE: X "o ""p"":(command=""lpr -P Photosmart_@192.168.5.103 -o cpi=12 -o lpi=8 -o page-left=72"")::""pipe"" s IO=""p"""

In human (ok in geekspeak), this last PRE-OPEN EXECUTE says, "Open a pipe device named "p" with the command to print to the CUPS printer named "Photosmart_@192.168.5.103". Set it to give us 12 characters/inch, 8 lines/inch and a 1 inch left margin). And then set IO to that device."

FileMan will then send his output to that IO device, the just-defined pipe.

Finally, the POST-CLOSE EXECUTE simply closes the pipe. And it's gone. No Linux /tmp/print.txt file to clean up. No fuss, no muss.

Another option is to define the device with option raw:
PRE-OPEN EXECUTE: X "o ""p"":(command=""lpr -P 1100A -o raw"")::""pipe"" s IO=""p"""
And then the SUBTYPE can manage the details of formating... Portrait vs Landscape and fonts, etc.

=== VistA output to a temporary Linux file (Calling ^TMGPRNTR) (older) ===

Below is an older way of setting up a Linux printer.

Here is the DEVICE file entry:

NAME: S121-LAUGHLIN-LASER
$I: <TO BE SET IN PRE-OPEN EX.>
LOCATION OF TERMINAL: Laughlin_Office
SUPPRESS FORM FEED AT CLOSE: YES
PAGE LENGTH: 70
PRE-OPEN EXECUTE: SET IO='''$$GETJOBNM^TMGPRNTR()'''
POST-CLOSE EXECUTE: DO '''FINISH^TMGPRNTR("laughlin_laser")'''
SUBTYPE: P-OTHER80
TYPE: HOST FILE SERVER

Here are the supporting calls to routine ^TMGPRNTR that create a file for writing, and then send the output file to the Linux lpr system

GETJOBNM()
;"Purpose: To create a unique printer job name.
;" This will be used during a printing process
;" that writes the printer file to the host file system,
;" then passes file to Linux
;" printing system.
;"Output: Returns name of file to put output into

;"UNIQUE will generate a filename based on time and job number
;" i.e. 'Print-Job-628233034.tmp

;"write !,"here in GETJOBNM^TMGPRNTR",!
new cJobs set cJobs="PRINT JOBS"
new Filename set Filename=$$UNIQUE^%ZISUTL("/tmp/Print-Job.tmp")

;"Now store Filename for later transfer to Linux lpr
new index set index=$order(^TMP("TMG",cJobs,$J,""))
if index="" set index=1
set ^TMP("TMG",cJobs,$J,index)=Filename

;"write !,"Print job name will be:",Filename,!
quit Filename ;"result returned by altering Filename

FINISH(Printer)
;"Purpose: to complete the printing process by sending the now-created file
;" to Linux CUPS (the printing system).
;"Note: The lpr system itself will delete this print file when
;" done (option -r)
;"Input: Printer OPTIONAL -- the name of the linux printer to send the job to.

new cJobs set cJobs="PRINT JOBS"
new index set index=$order(^TMP("TMG",cJobs,$J,""))
new Filename set Filename=$get(^TMP("TMG",cJobs,$J,index))

close IO
kill IO(1,IO)

kill ^TMP("TMG",cJobs,$J,index)
if Filename'="" do
. new CmdStr
. set CmdStr="lpr "
. if $get(Printer)'="" set CmdStr=CmdStr_"-P "_Printer
. ;"option -r --> lpr deletes file after printing done.
. set CmdStr=CmdStr_" -r "_Filename_" &"
. ;"write !,"Here is where I call:",!,"ZSYSTEM "_CmdStr,!
. zsystem CmdStr
. ;"write "Back from zsystem. Returning to Fileman.",!

quit

=== '''Linux /tmp/file (With ZSYSTEM call)''' (older) ===

On a Linux system with CUPS.

NAME: PRINTSERVER
$I: /tmp/vistaprint.txt
LOCATION OF TERMINAL: lpr
OPEN COUNT: 1
POST-CLOSE EXECUTE: X "ZSYSTEM ""lpr -r /tmp/vistaprint.txt"""
SUBTYPE: P-OTHER80
TYPE: HOST FILE SERVER

And for an elaboration of this method

NAME: HP-PHOTOSMART
$I: <TO BE SET IN PRE-OPEN EXECUTE>
PRE-OPEN EXECUTE: S IO="/tmp/"_$J_"print.txt"
POST-CLOSE EXECUTE: X "ZSYSTEM ""lpr -P Photosmart_@192.168.5.103 -r /tmp/""_$J_""print.txt"""
SUBTYPE: P-OTHER80
TYPE: HOST FILE SERVER

Note: This DEVICE does not require the calls to ^TMGPRNTR. And, by exposing the lpr call in the POST-CLOSE EXECUTE, it allows more flexibility. For example, this relatively simple change will direct output to the default CUPS printer with 12 characters/inch, 8 lines/inch and a 1 inch left margin. :

POST-CLOSE EXECUTE: X "ZSYSTEM ""lpr -o cpi=12 -o lpi=8 -o page-left=72 -r /tmp/""_$J_""print.txt"""
