 Best regards.
 Dmitry.
+
+== Additional Remarks ==
+
+The additional Epson printers listed above are now (as of version 9.00) included in Paul Smedley's distribution of GhostScript.
+
+It's possible to send the print job directly from the application --> GhostScript --> printer without having to go through the intermediate stage of running GSView.  This is made possible using the new [http://svn.netlabs.org/unipdr UniPdr] universal port driver:
+
+ * Install UNI.PDR (to \OS2\DLL)
+ * Create a new port of type UNI.
+ * Edit the port properties.  We need to send the print job through two programs: GhostScript, followed by whatever command actually sends the job to the printer.  Unfortunately, UniPdr doesn't seem to support piping the job through multiple programs, so you have to write a REXX script (or something similar) which does the work.
+
+I've used the following script to print to a TCP/IP (LPD) printer on the network:
+
+{{{
+/* GS2LPR.CMD - print to a TCP/IP printer through GhostScript, using LPR.
+ * The top-level GhostScript directory should be set in the environment
+ * variable GHOSTSCRIPT (or just edit the path directly in the file, below).
+ * Syntax: GS2LPR <model> <LPD server> <LPD printer> %file%
+ */
+PARSE ARG model server printer jobfile
+IF jobfile == '' THEN RETURN 1
+
+logdir = VALUE('LOGFILES',,'OS2ENVIRONMENT')
+tmpdir = VALUE('TMP',,'OS2ENVIRONMENT')
+gspath = VALUE('GHOSTSCRIPT',,'OS2ENVIRONMENT')
+IF gspath == '' THEN gspath = 'f:\gs\gs9.00'
+
+IF logdir == '' THEN logdir = tmpdir
+logfile = logdir'\gs2lpr.log'
+tmpfile = SysTempFileName( tmpdir'\GS_?????.TMP', '?')
+
+gscmd  = gspath'\bin\gsos2.exe -sDEVICE='model '-dBATCH -dNOPAUSE -sOUTPUTFILE='tmpfile' -q' jobfile
+lprcmd = 'lpr.exe -a 0 -b -s' server '-p' printer tmpfile
+
+'@echo off'
+IF STREAM( logfile, 'C', 'QUERY EXISTS') <> '' THEN CALL SysFileDelete logfile
+CALL LINEOUT logfile, 'Running GhostScript with command line' gscmd
+CALL LINEOUT logfile
+ADDRESS CMD gscmd '2>&1 >>'logfile
+CALL LINEOUT logfile, 'Return code:' rc
+CALL LINEOUT logfile, ''
+
+CALL LINEOUT logfile, 'Printing job with command line' lprcmd
+CALL LINEOUT logfile
+ADDRESS CMD lprcmd '2>&1 >>' logfile
+CALL LINEOUT logfile, 'Return code:' rc
+CALL LINEOUT logfile, ''
+
+CALL SysFileDelete tmpfile
+
+RETURN 0
+}}}
+
+Using the above, the following [http://svn.netlabs.org/unipdr UniLpr] settings will allow printing to a networked LP-9400 printer with TCP/IP address 192.168.1.100:
+
+ * '''Path and file:''' {{{cmd.exe}}}
+ * '''Parameters:'''    {{{/c c:\os2\gs2lpr.cmd lp9400 192.168.1.100 * %file%}}}
+
+You could presumably print to a Samba printer by using smbspool instead of lpr.  
+
+(''Don't'' try to print through CUPS -- i.e. with cupslpr -- using this technique, because the job will already be in printer-specific format at that point; CUPS expects to receive PostScript input, and will choke as a result.  In any case, you're presumably using this technique because printing via CUPS doesn't work in the first place.)
+
+It may also be possible to print to a local (LPT/COM/USB) printer using the OS/2 'print' command or somesuch program, but I haven't tried this.
