Epson 740 printer on 68030 Macs

I've been experimenting with the popular, inexpensive, and
readily-available (for the moment) Epson Stylus 740 printer on
officially unsupported Vintage Macs, and thought some of you might be
interested in my findings.
------------------------------------------------------------------------
The quick summary
Epson's System Requirements are correct for speedy, plug-and-play
operation. Still, those who can handle slow printouts and fiddling,
twiddling, and occasional instability may consider using a 740 with
030 Macs (i don't have an 020, and could therefore not test on
one).
Full summary
------------------------------------------------------------------------
Tested configurations
Most of my testing was on a 68030-based PowerBook 170, with
additional testing on a IIsi. I had hoped (for some reason not
requiring human logic) to get the thing to run on the 68000-based Mac
Plus. This did not happen, since the Epson software requires 32-bit
mode to run. It is PPC-oriented code (as one would expect), so the
only way it works on 680x0 Macs at all is via CFM-68k 4.0,
ObjectSupportLib 1.2, and their friends (all installed by the Epson
installers).
Two versions of the Epson driver software package were tested:
* The non-USB version on the Epson CD-ROM version 1.1 (installs driver version 5.50E)
* The current (as of when this was written) version from the Epson
website, package 5.5dE (installs driver version 5.57E)
Officially, as of early 1999 when i purchased this printer for my
parents, the 740 and the basic 740 driver software package (CD-ROM
version 1.1) was supported on System 7.1 or newer, 68040 or newer. I
recall that the version currently available on the Epson website
(5.5dE) demands System 7.5.1 or newer.
The majority of testing was under System 7.5.5. The printer
operated equally well from both the Modem and Printer port, though i
was unable to get it to work on the Modem port when AppleTalk was
active on the Printer port. Roadblocks (things which do not work as
they are supposed to work, in the order i found them)
The first roadblock when using the included Epson CD-ROM is that
Epson wants you to run a cute Macromedia Director movie to get to the
installer. Not enough memory on an 8MB PB 170 for this. Workaround:
dig for the actual installer, and launch that, which works. Or just
download the current version from Epson's website and use that. The
second roadblock was discovering the 32-bit mode requirement (i had
inadvertently left the PB in 24-bit mode).
The third roadblock was discovering that neither the older driver software from the Epson CD-ROM version 1.1 nor the current website version would work at all under System 7.1 Update 3, no matter what i tried (and i tried all kinds of wacky substitutions from later systems).
The fourth roadblock was discovering that the Epson driver
software assume a 640 X 480 screen, or larger. Users with smaller
screens (such as on the PB 170) will need a screen expander such as
SteppingOut for some of the screens (such as diagnostics/ink level),
though the basic Page Setup and Print screens are OK without
expansion.
Memory
From the Read Me:
Memory requirements: The printer driver uses the free portion of your computer's system memory as its working memory. The available memory is displayed as the "Largest Unused Block" in the About This Macintosh dialog box (accessed from the Apple menu). The memory requirements for printing a letter size full-page color image are as follows:
Minimum: 5MB (Foreground Printing), 10MB (Background Printing)
Recommended: 12MB (Foreground Printing), 21MB (Background
Printing)
These recommendations seem basically correct, although there are
some exceptions. I was able to get the printer to work acceptably
well on the 8MB PB 170 with VM off when printing small mostly text
files in SimpleText and WriteNow 4.02. There were occasional freezes,
esp. when opening the Page Setup window in WriteNow. Since all the
functions i tried worked at least some of the time, i suspect memory
issues. The printer will be much happier with Epson's recommended
memory (or more), though i did have very good results on the 170
using Background Printing with less memory than listed above. Plan on
having at least 16 MB of physical RAM, if possible, for the best shot
at stability.
Color image printing in JPEGView 3.31 did work, with caveats.
JPEGView and the Epson software could not print with 8MB, so i had to
turn virtual memory on (i used 13-15MB on various tests). With
background printing off, the sample image and a much smaller filesize
similar image each took over 1 1/2 hours to print (720 dpi Photo
settings). And don't assume for a moment that you can walk away...i
had to routinely dismiss "The printer is not responding" dialog
boxes. Turning on background printing totally eliminate the dialogs
in one test and reduced them to only one in another. Printing was
noticeably faster in both these tests with background printing on,
though still not mistakable for "fast" (about 1/2 hour).
Background printing usually helped. Things were stable enough that
i was able to play Forty Thieves while a background print was
printing (just a test; this of course slowed the printing down). Pure
black and white text documents at 360 dpi printed out over several
minutes, roughly twice as long as the same document, same software on
a PPC such as a PB 3400/240 or PM 8600/300.
Results were similar with OS 7.6.1 on the PB 170. Needing to
return the printer, i was unable to repeat each test under 7.6.1.
Though i did have one memorable freeze using Epson's Layout function
while in WriteNow, i had the sense that 7.6.1 would be a better
choice than 7.5.x for use with the Epson software.
Not many tests could be done on the IIsi, due to time limitations.
The tests which were done had similar results. The configuration was
System 7.5.5, VM off, 17MB physical RAM, FPU installed (no time to
pull it out). Speeds were similar, though it was clear that the Epson
software enjoyed the extra RAM. There was a strange, nonrepeatable
failure where the printer made a loud mechanical noise (i was out of
the room at the time) and ceased printing anything, with magenta ink
dribbling onto the page being printed. After resetting the printer
and running several cleaning cycles to restore printing, i repeated
the same print job (to the best of my ability; a WriteNow 4 sample
document with a watermark over it from the Epson software) with
flawless results.
Summary
It is possible to use the Epson Stylus 740 on at least some 68030
Macs. This is not recommended for casual or novice computer users,
nor those in a hurry. It is a viable option for Mac hobbyists who
want a nice, inexpensive 1440 dpi color printer for their 030 Mac,
provide their own tech. support, and don't mind occasional glitches.
Expect to spend some time "dialing in" everything for reasonable
stability. Try to have a minimum of 16 MB of RAM and System 7.5.5 if
at all possible. There was no function of the Epson software which i
tested which consistently failed to work (except on System 7.1, which
is not recommended). Some of my freezes were likely due to 8MB of
physical RAM. Others may have been due to a drag-install of crashed
extensions rather than an installer install of clean pieces.
Hope someone out there finds all this fol-de-rol useful.
