Compact rechargeable mobile direct-marking printer for applying dates, time, batch information, numbering and short text directly onto suitable products, packaging and components.

The REINER jetStamp® 990 is a compact mobile inkjet marking device designed for direct printing on products, packaging, components and documents.

Unlike a conventional stamp with fixed information, the jetStamp 990 can apply changing information such as:

• Date
• Time
• Batch information
• Consecutive or fixed numbers
• Short text

REINER positions the jetStamp 990 as a compact entry-level model for mobile direct marking. It is particularly useful where the operator needs to move between work areas or mark individual products without installing a fixed printing system.

A key operating advantage is that the user positions the device and presses the trigger button. The printing mechanism creates the impression without requiring the operator to swipe or manually move the printer across the surface.

Current REINER specifications identify USB and Bluetooth connectivity, up to 25 stored print images, a maximum imprint area of approximately 42 × 3.2 mm, and battery capacity of more than 2,000 impressions under the manufacturer's specified conditions.

The jetStamp 990 is also the current REINER successor to the earlier jetStamp 790 / 791 / 792 MP family, making it especially relevant when evaluating a new replacement for those established models.

What Is the REINER jetStamp 990?

The jetStamp 990 sits between a traditional hand stamp and a larger industrial coding system.

It allows electronically created information to be printed directly onto a product or surface.

For example:

LOT 25146

06.09.2026

or:

ITEM 004285

The information can be prepared electronically, stored in the device and printed where required.

This makes the jetStamp 990 useful for businesses that need variable direct marking without a permanently installed production-line printer.

Direct Printing Without Moving the Device

An important feature of the jetStamp 990 is the way the impression is produced.

With some handheld inkjet printers, the operator must move the device across the object during printing.

The jetStamp 990 works differently.

The basic process is:

Create the imprint

↓

Position the jetStamp 990

↓

Press the trigger

↓

Device automatically produces the imprint

There is no need for the operator to manually swipe the printer across the surface.

This can help produce more repeatable impressions and makes the device suitable for small marking areas where controlled positioning is important.

What Can the jetStamp 990 Print?

The jetStamp 990 is designed primarily for compact variable information, including:

Dates

Useful for production, inspection, processing and other date-based identification.

Time

Useful where time information forms part of the required marking.

Batch / Lot Information

Suitable for identifying production batches or internal processing groups.

Numbers

Fixed or consecutive numbers can be printed for internal identification and tracking.

Short Text

Article references, product information, short notes and similar information can be printed within the available print area.

The jetStamp 990 is therefore most appropriate when the required information is relatively compact.

Print Area

Current REINER technical specifications identify a maximum imprint size of approximately:

42 × 3.2 mm

The system supports:

Two lines

with up to approximately:

20 characters per line

depending on the selected character configuration.

This makes the jetStamp 990 particularly suitable for small marking areas.

Customers requiring substantially larger print areas, larger text, detailed graphics or more complex coding should compare other REINER models such as the jetStamp 1025 family.

Printing on Different Materials

REINER currently presents the jetStamp 990 for direct marking across a broad range of suitable materials, including applications involving:

• Paper
• Cardboard
• Wood
• Pallets
• Cans
• Glass
• Plastic
• Film
• Lids
• Closures

The exact ink should be selected according to the surface.

This is particularly important when printing on non-absorbent materials such as plastic, metal, glass or coated packaging.

Surface Compatibility Matters

A general description such as “plastic” is not enough to guarantee a particular printing result.

Different plastics may include:

• ABS
• PET
• PE
• PP
• PVC
• Acrylic
• Other polymers

Similarly, metal may be bare, polished, painted, coated, anodized or otherwise surface-treated.

Ink adhesion and drying can therefore vary.

For an important production application, the better approach is to evaluate:

Actual jetStamp 990

Correct Ink

Actual Product Surface

Required Imprint

Real Handling Conditions

before adopting the process for volume production.

Flat and Curved Surface Printing

The jetStamp 990 is not limited to completely flat products.

REINER specifically identifies it for use on flat and curved surfaces.

This can make it useful for products such as containers, closures and other objects where the available marking position is not perfectly flat.

REINER also offers dedicated positioning accessories for applications requiring more consistent placement on small, curved or sensitive objects.

The actual curvature and available print area should still be checked before choosing the device.

PCset Configuration

REINER's PCset software is used to create and manage applicable print images.

A typical workflow is:

Create Required Imprint in PCset

↓

Transfer Information to jetStamp 990

↓

Position Device

↓

Press Trigger

↓

Print Directly on Product

The jetStamp 990 can store up to 25 print images, allowing frequently used formats to remain available in the device.

USB and Bluetooth Connectivity

Current REINER specifications identify:

USB

and

Bluetooth

for data transmission.

This gives the jetStamp 990 greater flexibility than earlier-generation jetStamp products when used in modern digital workflows.

REINER also describes integration possibilities involving PC software and, depending on the workflow and system implementation, applications such as office software, ERP environments and label software.

Specific integration requirements should be evaluated before purchase rather than assuming automatic compatibility with every business system.

Rechargeable Mobile Operation

The jetStamp 990 uses rechargeable battery power, allowing it to operate away from a fixed power connection during normal marking tasks.

Current REINER specifications state a battery capacity of more than 2,000 impressions under the manufacturer's specified operating conditions.

Actual operating capacity can vary according to:

• Battery condition
• Usage pattern
• Bluetooth activity
• Operating environment
• Device settings
• Age of the rechargeable batteries

The battery rating should therefore be treated as a manufacturer operating specification rather than a guaranteed number for every deployment.

jetStamp 990 vs Earlier 790 / 791 / 792 MP Models

The jetStamp 990 is particularly important for customers currently searching for older REINER equipment.

REINER identifies the jetStamp 990 as the successor to the earlier:

• jetStamp 790
• jetStamp 791
• jetStamp 792 MP family

Customers replacing an existing older device should still compare the complete application before changing models.

Compatibility of inks, accessories, software and established operating procedures should not be assumed merely because the 990 is the successor.

For a new mobile direct-marking application, however, the jetStamp 990 is generally the more relevant current REINER model to evaluate.

jetStamp 990 vs jetStamp 1025

These products address different marking requirements.

jetStamp 990

Better suited to compact direct marking where dates, numbers, batches and short text need to be printed within a small area.

Maximum imprint: approximately 42 × 3.2 mm

jetStamp 1025

Designed for substantially larger and more sophisticated direct-marking requirements, including larger print areas and applications requiring additional content capabilities.

Customers should therefore choose according to the required print content and physical print size, rather than assuming that a larger device is automatically better.

Accessories

REINER offers accessories that can extend the jetStamp 990 for specific workflows.

Depending on the application, these can include:

Positioning Plate

Helps achieve more repeatable positioning on suitable curved and sensitive objects.

Positioning Mat

Supports consistent positioning for appropriate small or curved products.

Foot Switch

Allows external print triggering in suitable workstation workflows.

Holding Arm

Supports more controlled and repeatable positioning.

Transport / Storage Case

Provides organized protection for the device during transport or storage.

Printing Stations

REINER also offers dedicated workstation accessories for selected packaging and document-marking applications.

Accessory compatibility and exact requirement should be confirmed before ordering.

Applications

The REINER jetStamp 990 may be considered for:

• Manufacturing
• Warehousing
• Shipping
• Production
• Packaging
• Food-sector marking applications

It can reduce dependence on:

• Pre-printed labels
• Conventional adjustable stamps
• Handwritten information
• Fixed marking equipment

when the actual application is suitable for direct inkjet marking.

Whether direct printing is preferable to labels depends on the material, required durability, print content and operating workflow.
